2012: the Good, the Bad and the Ugly - Part Deux!

Yup that would be a stupid bimbo sinking on a dead Shark - but check out the caption and the comments! Sigh.

The Bad and the Ugly!


Sorry for keeping you waiting!
So this is what y'all been waiting for - with bated breath no doubt!
This is when, to paraphrase Vee and the nieder-Jupp, my vicious soul and inferiority complex compel me to insult and belittle others - this all in order to get attention, elevate myself at the expense of others, become famous and get the chance to finally travel with a retinue of shapely bimbettes, just like my secret hero ABC4!

But more seriously
This is when somebody will inevitably start shouting, how dare you attack fellow conservationists, and invoke global peace and harmony and-so-on and-so-forth.

So lemme state this loud and clear: I don’t hate anybody here.
Hell, I don't even really care about those people!

What I however DO hate is bullshit!
And in the spirit of qui tacet consentire videtur, I will always reserve the right to criticize situations I don’t agree with - and if they happen to be in the public domain, I will also feel perfectly entitled to do so publicly, like it or not!
I also believe that like in science, progress in conservation is achieved via dialogue but also, via robust debate where opinions may get heated but where everybody who is legit accepts that those are just the rules of the game – and where those who do not are simply not scientists and conservationists but posers and bullshitters!

In brief, where I’m coming from is that whereas it is great that Shark conservation has become sizzling hot and is uniting many passionate voices around a great common cause, bullshit continues to be bullshit and shenanigans, shenanigans - and the great common cause is in no way an excuse for any of that.
And like in real life, people are sometimes simply incompatible and thus mutually exclusive.

If you don’t agree, stop reading now - HNY and have a great life!
Seriously, spare yourself the aggro because the following aint gonna be pretty – but if you cannot resist and end up being outraged, spare me the lessons in ethics and instead, debate the assertions!
Seriously!

If the meteoric rise and the astounding successes of Pew teach us one lesson, then it is that the correct way to save Sharks is to pursue their protection by pragmatic and science-based advocacy and by hard work and smart negotiations aimed at legislative changes.
The rest is just stupid fluff and hot air, and counter productive to boot. We are not the ones who enact Shark protection - and rest assured that the people who do have zero time, zero patience and zero respect for the vocal clamoring of the Shark whacks!

Again, Shark conservation is inextricably liked to political and economic considerations, and he who does not understand that is just a fool.
Shark fishermen don’t hate Sharks, they want to make a buck – and the authorities don’t subscribe to conservation because they have changed their perspective and suddenly love Sharks, they do so because they have been convinced of the (eminently economic) need for sustainability and in the case of Sharks, because they have learned about the importance of several (not all!) species in regulating the marine environment and thus, of their economical value all the way to generating millions in income from tourism.

Shark finning?
The finning bans are archaic and ineffective and thus not anymore worth pursuing in isolation. Yes finning is an ethical abomination and needs to be abolished – but what is killing the Sharks is Shark fishing and if you care to open your eyes, you will quickly discern that many of the major Shark fishing hubs are processing the whole animals as the meat is increasingly sought after by ever increasing populations starving for protein, and other products like leather, squalene and even the eggs are introduced into the wider economy.

The facts and numbers?
Science is in continuous flux and the data do indeed change – but until they do, the latest peer reviewed science (but also read this and this!) remains the best approximation of the truth.
Thankfully, there are now plenty of resources where anybody can consult the latest insights and data, meaning that those who continue to operate with inflated statistics and outlandish assertions lack any excuses and credibility whatsoever. The facts are plenty horrible as it is – so let’s please stick to those and refrain from the usual stupid inflated hyperbole!

The industry?
If there has been one trend at this year’s DEMA, then it has been Shark conservation - and everybody in the dive industry is now claiming that he has always been deeply and passionately involved.
Great – if only they all did walk the talk!

Instead, the usual shenanigans have continued unabated.
Don’t get me wrong, I know that nothing is just black or white. Competition is continuously leading many Shark diving operators to ever up the ante, this also very much in order to satisfy the continuous requests for ever more adrenaline by their clients. There is also an insatiable demand for images featuring stunt work with Sharks.
I understand that these are businesses and that those folks are merely trying to make a buck – but I certainly do not subscribe to the notion that these developments are inevitable, the more since we at BAD are doing very well indeed by promoting a totally different kind of experience, do not enable Shark porn and have in fact continuously tightened our protocols as a result of the stupendous increase in large Sharks visiting Shark Reef.

But you can’t have it both ways.
Stunt work with Sharks and promoting gratuitous adrenaline thrills got nothing to do with Shark conservation, period!

And the much-invoked Demystifying and Changing Perceptions about these Misunderstood animals?
Indeed - respectable Shark diving operations do that daily, and this without having to resort to those stupidities, and so do respectable Shark media!

Think about how the same was achieved with the terrestrial top predators: certainly not by showcasing scantily clad death-defying bimbettes (Bikini Shark Warrior? C'mon girl - you're better than that!) perambulating in the savannahs and the Sundarbans and also not by turning alpha predators into pets by allowing tourists to physically interact with them, let alone ride them!

E.g., what is this shit - and no it was not with Epic Diving!


Changing perceptions by attempting to “prove” that we’re not on the menu of Sharks actually perpetuates the myth by reducing the animals’ fascinating and complex life history to one element only, that of shark-human interactions where some of the large species actually do devour people – which makes them neither Bad not Good but merely illustrates that they are the opportunistic predators they just happen to be!

Nobody in his right mind asserts that Lions and Tigers are harmless – but most of us have learned to respect and love them for what they are, beautiful, charismatic and awe inspiring essential elements of their natural habitats, and very much endangered.
Think BBC documentary: that’s how you do it – and yes, the rest is just moronic BS!
And: Love not Loss - remember?

Ring a bell?
It better - because I've basically copy/pasted what I've written last year!
Yes, alas, nothing has changed much - and I'm frankly too lazy and also lack the profound motivation to try and re-formulate the exact same message in the hopes that choosing other words may change the outcome!

WARNING!
In keeping with what constitutes REAL messaging in Shark conservation, the following will contain a liberal dosing of CAPS LOCK!

The Dolphinization of the Shark Conservation Movement

So, what's going on?
Why is it that after years of attempts at educating the public and of trying to weed out the most irritating myths, those people still continue to spout these inanities - and mind you, I'm talking about the people on OUR side, not the Shark haters?

Look no further than here!



Need I elaborate?
The question of course is, how do we proceed if we want to stop preaching to the choir and instead broaden our base and activate the masses that by definition are dumb (and I'm not even talking about the retards!) - the more as the most popular communication vehicles are demanding ever shorter messages, see Facebook, Twitter et al!

I've been discussing this with one of the science communication senseis, the great Randy Olson, and his answer is, you got to tell a compelling story - one that appeals to the gut and the emotions rather than the brain!
But hear it from da man himself!!



Easier said than done - right?
The challenge of course is to be interesting, entertaining, informative and on top of that all, synthetic - this however without succumbing to the temptation to shorten and dumb down the message to the point where its veracity is being compromised!
And here is obviously where most Shark conservation messaging fails!

I really did like this comment on David's post about the same issues.

Kirsten E
Popularizing science is a very difficult thing to achieve. It is worth considering that misinformation becomes widespread because it appeals to the general public’s sense of Right and Wrong, where soundbites with some tenuous connection to a factual foundation fit firmly into a black and white worldview. It is not surprising that sympathetic individuals fall prey to exaggerated claims, because they lack the background, ability, or dedication to look deeper.
I am guilty of being a bit of a loudmouth when discussing shark conservation, but as it is my intended career path I am always looking to further my knowledge. The difficulty is that most people’s introduction to these issues is not from researchers, but from organizations like Sea Shepherd or documentaries like Sharkwater, who seek a reactionary, emotional impact to make a point. Once that impression is made, it is very hard to scale it back to a more realistic discussion, perhaps because it lacks the same shock factor that appeals to people’s indignation in the first place.
It’s ironic that conservationists can be their own worst enemy.

AMEN!

Which brings me to the second issue here.
Once the scientists and conservation orgs broaden their outreach, the messaging is then picked up and multiplied by others - the bleeding hearts and idealists that consitute the movement I call Sharktivism.

And the result of those efforts?
Look no further than the Infinite Monkey Theorem!



Examples?
Here's just two from a never-ending succession of wrong or distorted "information" bombarding the public - and because these people are certainly well-intentioned, I refrain from adding the links.
You know who you are!

We need to get these extremely vulnerable and critically endagered Porbeagles listed in CITES appendix I or we can put the few pictures which exist of these magnificent animals in a museum!

But Porbeagles are only critically endangered REGIONALLY!
And consequently, they ARE being protected nationally and regionally and the advocates are proposing to have them protected by the relevant RFMOs (so far successfully in one but in vain in another) and to list them on CITES II and not I!

To make shark's fin soup, fishermen catch sharks and cut off their fins.
They throw the rest of the shark back into the ocean because the meat of the shark is considered less valuable and not worth keeping. The sharks are often still alive and left to slowly drown because without their fins they can no longer swim!

But the soup's recipe does not require finning - right?
Finning is perpetrated by OTHERS (very much including us supercilious westerners!), and this for  reasons of convenience and greed! But granted, yes, it happens all-too-often - so is this compression of a long story legit?
Probably YES - but then, once the Chinese (!) whispers pick up and propagate the meme, it inevitably leads to racist rants and to crap like

the practice of shark finning results in an estimated 73 million sharks a year being killed for their fins alone and that over one-third of all shark species are threatened with extinction as a result of shark finning;

Oh yes that would be once again be the United Conservationists - see Part Three!
AND: finning is not the real issue - the real issue is OVERFISHING! Are we advocating  CONSERVATION or are we ANIMAL WELFARE activists?

So lemme repeat this - again!

If we want to be credible Shark advocates, we got to do our homework and first of all, be informed about the animals we love!
Science is always in flux and today’s insights may quickly become tomorrow’s fallacies, meaning that we must keep abreast of the latest research results and not base our knowledge on old publications and approximate hearsay.

Most importantly, we the amateur naturalists should never make up things on the fly, nor should we idly re-interpret what is considered to be the accepted consensus.
This does not mean that we should not challenge the current status quo, as that is precisely the process by which knowledge is being advanced! BUT: the only accepted technique for doing so is the Scientific Method and as always, let me warn against the siren calls and intellectual shortcuts of the self promoters, quacks and charlatans!

Every single researcher I’ve ever met has always been eager to engage in informed discussions and to entertain different hypotheses, if adequately supported by according observations.
Those researchers are neither omniscient nor omnipresent and often, observations by common mortals like us have greatly contributed to the advancement of scientific insights - so even if you have no academic background, don’t be shy and speak up!
But do your home work first!

Can we maybe just be a little more humble and less righteous, the more since Conservation is so complicated  - and maybe progress towards more facts and less truthiness?
Can we maybe just open our eyes and wonder at the magnificence of what IS instead of trying to make things up?

It is that very deluge of platitudes, pseudoscience and exaggerated doomsday scenarios in all those pedestrian wannabee Sharkwater clones, those zillions of activist Facebook pages and those idiotic petitions that is undermining the legitimaticy of Shark conservation by making us all look like total wingnuts!

We are the amateurs.
Can we please listen to what the professionals are telling us – the principal message being that extreme positions (on both sides!) are inhibiting conservation and appropriate management measures?

AND, here's another one I need to get off my chest!

The Shark Con

No not the ramblings of HE Sawyer!
That's just whackadoodle gibberish!

I'm talking about misleading conservation messaging that is coupled with an AGENDA.
Mostly, it is obviously about the money. Sometimes, it is about the money plus other motivations, e.g.  narcissistic self promotion like in the case of Ms. Andersen, see Part Four.
In my book, it becomes a CON when the bullshitting is INTENTIONAL.

Examples?
That's a difficult one as in practice, it is often difficult to differentiate from the equally idiotic and misleading statements of people who are actually well-meaning but who think that resorting to hyperbole constitutes legitimate "marketing", or of people who simply parrot the stupid statements of others - or of people who are simply stupid!

Case in point, once again from David's post.

David McGuire (@Seastewards)
........
Given the scanty data for the MSC “sustainable spiny dogfish fishery” it remains to be seen whether there really can be such a thing. Included in the definition should be negligible to no bycatch. It that category the Southern California drift gill net fishery fails. Thousands of blue sharks, other species of sharks including Great White Sharks, marine mammals and sea turtles are all killed as bycatch in the thresher shark fishery (and now Mako where the population is data deficient).
David McGuire, Shark Stewards

To which a reader responded.

@Seastewards
I get worried when I see such comments from a shark conservation organization leader like yourself that collects peoples donations. Folks like you worry me because you are irresponsible and you mislead the public.
“Included in the definition should be negligible to no bycatch. It that category the Southern California drift gill net fishery fails. Thousands of blue sharks, other species of sharks including Great White Sharks, marine mammals and sea turtles are all killed as bycatch in the thresher shark fishery (and now Mako where the population is data deficient).”
Currently, over 90% of the total bycatch by numbers in the DGN fishery comes from a single species, the common mola (sunfish). Although there has not been a definitive study on the survivorship of common mola released from DGN gear, observations by NMFS observers and researchers suggest that a high percent (>90%) of them are released alive.
Here is a link to info regarding shark bycatch in California’s drift gillnet fishery, you might learn something here:
As far as great white shark bycatch, the numbers are a non-issue as you can see here:
Pingers have lowered bycatch of cetaceans by 50% (Barlow and Cameron 2003) and the 6 fathom extenders (buoy lines) have drastically reduced bycatch of California sea lions and CTS which are typically near the surface at night when the nets are being dragged.
California’s drift gillnet fishery hasn’t killed a sea turtle in 13 years. Here is a link to prove it:
Do your homework Mr. David McGuire. You owe it to the folks that donate to your organization and the sharks you claim to protect.

Bingo!
So is McGuire just an IDIOT who spouts unverified factoids, or is he a CHARLATAN who is amping up the rhetoric in order to be more successful when soliciting funding, or BOTH? 
You be the judge of that - but he is certainly IRRITATING, and has been so for a very long time indeed! Not quite enough for a nomination - but he's certainly on the waiting list!

Solutions?

On the positive side, LET US TELL A GOOD STORY!
Don't know how to do that? Read this - and if you're an org in the USA, book a seminar with Randy!
Oh yes - and read his blog - see the blog roll on the side!
(howz that for a shamelesss plug, buddy! :)

Example!



On the negative side, LET'S CALL OUT THE PERPETRATORS!
And NO I do NOT agree with Randy on this one: - no gravitas and decorum here mister, ever! I shall NOT watch my language, and I specifically reserve the right to continue saying FUCK, and this in CAPITAL LETTERS, whenever I please!

And what about the comments section?
Moderation is enabled and the WAILING OF HYENAS (love it!) will only be tolerated for entertainment and/or educational purposes!

To be continued!

Weekend Rant!


Time for a rant!

From a message by a friend

Agree that there is much breathy hyperbole and blatant nonsense written about sharks and conservation, but I suppose that this is inevitable when concern is high but facts are few, with the most solid data residing in relatively inaccessible scientific papers.

Generally I take a sanguine or even charitable view toward the popular Jeremiads you have castigated since the goals of the authors are generally in concordance with mine, and these often painfully well-intentioned folks are far more able to communicate values effectively and educate a large audience than someone who uses words like sanguine or Jeremiad, no?
And education does seem to work in the long run.

Totally agree – BUT!
I’m getting terminally irritated that people who purport to be Shark conservationists and are perceived to represent the whole movement continue to make public statements containing ludicrous assertions and statistics.
This is not only not helpful - it directly undermines our efforts by allowing the other side to assert that we’re nothing but a bunch of lunatics who operate with false claims.
Is that what we want?

Yes it’s an old grievance of mine – but enough is enough.
So there.

But first, check out this piece of equine manure!
Very timely indeed – thank you!



Wow!
Pure sharkitarian snake oil!

There are no Shark attacks?
Right!
Please re-read this!

Sharks?
When talking conservation, talking about “Sharks” is utterly useless!
The fact is that “Sharks” are neither threatened with extinction, nor are "they" apex predators – only a small minority of species are apex predators, let alone keystone species, and the species that are particularly at risk of extinction are several large predatory Sharks, many of which are pelagic; possibly some deep water Sharks; and maybe Whale Sharks – full stop!
Other species are doing no better and no worse that any other Fish that is not subjected to exceptional fishing pressure – meaning not particularly great but not particularly catastrophically, either.
List here (search for "Sharks"), criteria here.

The numbers?
The numbers are just that, numbers.
If one does not put them into context by comparing them to what we know about individual species in specific locations, they say nothing about sustainability which is the only thing that counts.
Yes we all know without having to resort to peer reviewed science that many local, and possibly even some global populations of some Sharks have been severely depleted, and that their disappearance is of concern – but for the time being, that’s basically all we can assert.

So far, there has been one single paper trying to shed a light on the actual numbers being caught, and this only based on data from the Shark fin trade. Read it!
The paper is based on a series of (probably plausible) assumptions that are heaped upon more assumptions, and consequently, the results are merely expressed in orders of magnitude. Specifically, the authors come to the conclusion that the fins traded annually came from between 26 and 73 million Sharks, with a median number of 38 million.
Does that really allow us to honestly state that up to 73 million Sharks are being killed each year, as everybody and his dog has started to assert?
Kudos to Seafood Watch for doing it right: It's estimated that tens of millions of sharks are killed around the world each year for their fins is much better - but then again, have they been killed for their fins?

As I said, the above numbers are only about the global Shark fin trade alone.
They do not cover many other Shark fatalities due to bycatch or targeted food fisheries where the fins are not being introduced into the fin trade. Also, that was then and the trade has very likely increased since. It is thus entirely plausible to assume that the “real” number is higher, and it is perfectly OK to say so.
It is however totally unacceptable to make up numbers on the fly, be it as many as 100 million, let alone over 200,000 million (!!!) which is just plain ludicrous and quite frankly, a total disgrace! Yes, I'm being frank! :)
The good news is that I know that somebody is working on a peer reviewed paper about the global number of Shark being killed – but once again, unless put into context, those numbers will mean absolutely nothing!

And what about the Rate of Depletion?
Is it really true that 90% (or 99, or 70 – whatever!) of global Shark stocks have already been wiped out? Compared to which original baseline count, done when, where and by whom?
Where are the data?

And is it really true that Some marine biologist have suggested as soon as 2020 these magnificent creatures may be extinct – and if so, who is claiming such utter baloney?
Those endangered species of Sharks will become commercially extinct long, long before they will become biologically extinct! But there's a caveat: it is however probable that some local populations may have shrunk to the extent that they may have accumulated extinction debt and that they may be too small to be able to withstand the pressure of a large environmental shock, like the current anthropogenic Climate Change – re-read this post!

Shark Finning?
Shark finning does not equal catching Sharks. It is a specific, particularly wasteful and particularly cruel harvesting technique and for these reasons alone, it certainly needs to be stopped.
But is everybody aware that stopping the finning does not necessarily stop the fishing? The most widespread remedy against Shark finning is to legislate that the Sharks must be landed with their fins attached. This reduces the number of Sharks that are being killed as the carcasses take up a lot of space in the hold of the vessels – but as many examples show, Sharks are still being landed with their fins attached in what clearly appear to be unsustainable numbers.
Also, in many third world countries, local fishermen (and poachers!) have already wiped out many of the traditional food fisheries and as a consequence, many people have added Sharks to their menu, meaning that there is a substantial and increasing Shark food- , as opposed to Shark fin fisheries.
Thus, if we want to save Sharks stocks from overfishing, Stop Shark Finning! petitions alone are simply not adequate – we must also campaign for their protection!

Also, not every fin that is being sold has been finned!
Statements like over one hundred million sharks are caught and finned alive are thus doubly misleading!

Cascading Effects?
Yes there is a seminal paper by Myers et al. that essentially shows how the removal of large predatory coastal Sharks in the Northwest Atlantic led to the explosion of the population of Cownose Rays who in turn wiped out the Scallops, and the industry depending on them, in Chesapeake Bay. More details here.
Great paper – but it has one weakness: nobody was harvesting those Cownose Rays!

But in the real world, coastal Sharks are not being selectively removed alone.
Instead, fishermen target both the apex- and the mesopredators (and the prey), meaning that asserting that removing the big Sharks will inevitably lead to a population explosion of mesopredators (many of which are incidentally Sharks!) who in turn will wipe out the grazers which in turn will lead to an explosion of algae who in turn will smother the reefs can be totally wrong.
In a way, it is now us who have unwittingly assumed the role of apex predators and are keeping the lower trophic levels in check – see many terrestrial habitats where most apex predators have all but disappeared but where there has not at all been a total collapse of the system!
I’m not saying it is not so: I’m just saying that the empirical evidence is scarce and that once again, those effects will vary according to habitat and species composition.
See Ferretti et al. for more details!

As to the role of Sharks in their habitat and the widespread explanation that they weed out the sick and dying and thus keep the gene pool of their prey healthy, etc?
Certainly intuitively plausible: but to my knowledge, whereas there is plenty of research about the role of terrestrial predators, such effects have not been conclusively documented for Sharks – yet!

Which brings me straight over to Climate Change and Oxygen Production!
Check this out.



Did you hear that?
Who has come up with the glorious idea of linking Shark conservation to the Oceans’ production of oxygen?
Yes the Oceans provide for about half of the planet’s oxygen production through the photosynthesis by phytoplanktonic Algae and Cyanobacteria (but then again, probably not!). This (incidentally, to a very small extent), and the sea water’s capacity to dissolve CO2 make it that the Oceans are also Earth’s largest active carbon sink.
It is also certainly true that the Oceans have a great influence on the weather, and that millions of people depend on them for food.

But this got nothing to do with Sharks!
The principal threats to oceanic ecosystems are probably Climate Change, Acidification, Overfishing, Pollution and Habitat Degradation – not the fisheries for Sharks!
It is just not plausible and there is certainly no scientific evidence indicating that if one selectively removed all Sharks
- the oxygen production would cease due to the disappearance of phytoplankton
- the oceans would cease to be a carbon sink
- the weather would change
- fisheries would collapse and humankind would starve
or any other similar stupidities that happen to be en vogue among some Shark activists!

Shark Intelligence?
This very much smells like the newest up-and-coming Shark conservation fad.
Does the fact that some Sharks migrate and that they are capable of memorizing locations automatically mean that they are particularly intelligent? Why are some quarters asserting that it is so, when this is in no way being claimed by the authors of those migration papers?
Sorry Richard – I still think you rock! ;)

Are Monarchs particularly intelligent? Wildebeest?
What about Bees who are not only capable of finding and memorizing the location of a food source, but then also fly back to the hive and convey that information to the other bees – so effectively. that those other bees can find the food without being guided there by the finder?
Hell, that’s even smarter than what we know about the so much hyped Dolphins!

Frankly, I dunno.
My gut tells me that migration and spatial orientation are not good indicators for intelligence. Yes it is amazing behavior – but animals doing amazing things are more often than not simply well adapted to their ecological niche, and behavior that comes across as being remarkably clever is often hard wired and the result of evolutionary selection as opposed to volition.
Example? The amazing Anglerfish!
Perfectly camouflaged and provided with an ingenious lure, they are highly successful at ambushing their unsuspecting prey. Totally clever – and yet one of my ichthyological gurus assures me that they dispose of the lowest brain-to-body mass ratio of all Fishes!

Sharks BTW have a relatively high brain-to-body mass ratio, somewhere between Teleost Fishes and Mammals..
But although we all intuitively know what intelligence means conceptually, it is nevertheless difficult to define, especially in animals - and even more difficult to compare, see the Bees and the Dolphins!

When it comes to Sharks, the one person who knows most about the topic is probably Doc who has demonstrated remarkable learning and problem solving capacity in Lemons, very much in line with what we experience daily with our Bulls.
My gut feeling is that as always, different species will display different abilities, and that those predatory species with the widest trophic niches requiring the widest range of predatory strategies and thus the highest adaptive capabilities will be perceived as the most intelligent - but then again, a friend may be on to something when he remarks
Incidentally, since humans filled a generalist predator niche at one time before we graduated to planetary predator class, would we not inevitably tend to think that other generalist predators like sharks are particularly intelligent?
Yes, it's complicated!

Still, I fully agree with Wolfgang that Tiger Sharks come across as being way smarter than, say, Whale Sharks that I incidentally perceive as being particularly dumb - and who incidentally migrate like crazy!

But those are clearly personal perceptions, not objective data.
Whereas I’m convinced that all of our Bull Sharks have distinct personalities and that they develop affinities to specific persons, I also know that we humans have a fatal propensity for anthropomorphism, i.e. for attributing human faculties to animals.
So, yes, let’s love them like crazy – but let us not assert that our feelings are being equally reciprocated, or the like!
Yes Emma very much appears to love Jim (and there’s absolutely no doubt whatsoever that Jim loves Emma!) – but she is very likely being bribed with massive amounts of juicy handouts and is just being the opportunistic feeder Tiger Sharks are!

Having said that, there appears to be clear evidence that the behavior of some Sharks goes well beyond that of mere automatons that are solely driven by genetic programming.
In fact and going back to, say, Tigers and Bulls, aren’t high flexibility and adaptive capability precisely what we would expect evolution to select for in a generalist predator – meaning that some of what we perceive as being intelligent behavior may be genetically encoded, but that there must also be scope for individual decision making, individual learning, individual preferences, individual personality, etc. which may indeed be good indicators for intelligence.
Again, I don’t know - but precisely because of that, I would never proffer any strong statements one way or the other!

Long story short?
If we want to be credible Shark advocates, we got to do our homework and first of all, be informed about the animals we love!
Science is always in flux and today’s insights may quickly become tomorrow’s fallacies, meaning that we must keep abreast of the latest research results and not base our knowledge on old publications and approximate hearsay.
Most importantly, we the amateur naturalists should never make up things on the fly, nor should we idly re-interpret what is considered to be the accepted consensus.

This does not mean that we should not challenge the current status quo, as that is precisely the process by which knowledge is being advanced!
BUT: the only accepted technique for doing so is the Scientific Method and as always, let me warn against the siren calls and intellectual shortcuts of the self promoters, quacks and charlatans - see on top!

All researchers I’ve ever met have always been eager to engage in informed discussions and to entertain different hypotheses, if adequately supported by according observations.
Those researchers are neither omniscient nor omnipresent and often, observations by common mortals like us have greatly contributed to the advancement of scientific insights - so even if you have no academic background, don’t be shy and speak up!
But do your home work first!

Or, as I said before .

Can we maybe just be a little more humble and less righteous, the more since Conservation is so complicated?
Maybe progress towards more facts and less truthiness (read this!)?
Can we maybe just open our eyes and wonder at the magnificence of what IS instead of trying to make things up?

We are the amateurs.
Can we please listen to what the professionals are telling us – the principal message being that extreme positions (on both sides!) are inhibiting Conservation and appropriate Management measures?
Recent example? Right here – like it or not, the man has a point!

If we want to educate others – let’s educate ourselves first!

And here endeth the weekend rant!

PS Patric's take: WOW!!!

The Numbers: The Chickens have come home to roost - again!

Dead Sharks in Kesennuma. No, this NOT about Shark Finning, and no, they have NOT been killed for their fins alone or the like!

Oops indeed!
From my Weekend Rant.
The numbers?
The numbers are just that, numbers.

Is it really true that 90% (or 99, or 70 – whatever!) of global Shark stocks have already been wiped out? Compared to which original baseline count, done when, where and by whom?
Where are the data?

And is it really true that Some marine biologist have suggested as soon as 2020 these magnificent creatures may be extinct – and if so, who is claiming such utter baloney?
Those endangered species of Sharks will become commercially extinct long, long before they will become biologically extinct! But there's a caveat: it is however probable that some local populations may have shrunk to the extent that they may have accumulated extinction debt and that they may be too small to be able to withstand the pressure of a large environmental shock, like the current anthropogenic Climate Change – re-read this post!
...
Also, not every fin that is being sold has been finned!
Statements like over one hundred million sharks are caught and finned alive are thus doubly misleading!
...
If we want to be credible Shark advocates, we got to do our homework and first of all, be informed about the animals we love!
Science is always in flux and today’s insights may quickly become tomorrow’s fallacies, meaning that we must keep abreast of the latest research results and not base our knowledge on old publications and approximate hearsay.
Most importantly, we the amateur naturalists should never make up things on the fly, nor should we idly re-interpret what is considered to be the accepted consensus.

This does not mean that we should not challenge the current status quo, as that is precisely the process by which knowledge is being advanced!
BUT: the only accepted technique for doing so is the Scientific Method and as always, let me warn against the siren calls and intellectual shortcuts of the self promoters, quacks and charlatans - see on top!

All researchers I’ve ever met have always been eager to engage in informed discussions and to entertain different hypotheses, if adequately supported by according observations.
Those researchers are neither omniscient nor omnipresent and often, observations by common mortals like us have greatly contributed to the advancement of scientific insights - so even if you have no academic background, don’t be shy and speak up!
But do your home work first!

Or, as I said before .

Can we maybe just be a little more humble and less righteous, the more since Conservation is so complicated?
Maybe progress towards more facts and less truthiness (read this!)?
Can we maybe just open our eyes and wonder at the magnificence of what IS instead of trying to make things up?

We are the amateurs.
Can we please listen to what the professionals are telling us – the principal message being that extreme positions (on both sides!) are inhibiting Conservation and appropriate Management measures?
Recent example? Right here – like it or not, the man has a point!

If we want to educate others – let’s educate ourselves first!

That was in March.
Now, the lead author of the numbers paper (yes it is open source and available online - read it!) Shelly Clarke, has reached out with a wail of despair about the way Shark advocates are abusing the numbers she has estimated. It's the Shark Con all over again - and talk about a pathetically flat learning curve!

And I cite.

Exaggeration and hyperbole run the risk of undermining conservation campaigns.
Presenting a high but scientifically unsubstantiated number like 100 million can discredit otherwise valuable advocacy for better resource management and monitoring.

Pretty bloody embarrassing huh.
Pretty bloody dangerous too, as now the other side can rightfully claim that the lead author of the only paper dealing with the issue is asserting that Shark conservationists operate with fake data. So as a reminder, here's the actual citation from the paper, hidden somewhere in the general scientific gibberish at the bottom of page 119.
Estimates of the total number of sharks traded annually worldwide, based on all fin positions combined, ranged from 26 to 73 million year-1 (95% PI), with an overall median of 38 million year -1.

Not very helpful is it.
Couldn't she have said it like in her post, i.e. as of 2000, the fins of 38 million sharks per year were being traded through the fin markets, but the number could range as low as 26 million or as high as 73 million? Could she not have put that estimate into the Abstract at the top?
But, it is what it is - and anyway, those numbers mean nothing unless put into context!

Long story short?
We gotta stop exaggerating and making things up - is that so difficult to understand?

Which brings me straight over to the Oxygen.
Claiming (one of dozens, talk about a bloody memetic viral infestation!) that if the Sharks get wiped out we will all suffocate is just total unadulterated rubbish! Period!
And if that were not stupid enough, I already get a whiff of the attempt of linking Sharks and Global Warming! WTF?

How long til that, too, will bite us in the ass?
It is, as always, up to us!

Shark-proof Wetsuits - Questions by Mark Gray!

Source.

And it gets even better!

Mark is this dude.
A renown Shark photographer, he is above all a fellow Shark diving industry professional - and having discovered those Shark repellent wetsuits, he has taken on SAMS and is publicly, and doggedly asking precise questions about their, and I cite, scientifically designed and developed shark repellent wetsuit technology.

I c/p it lest as so often, it gets "accidentally" deleted - much like the mentioned "other posting" that has disappeared from SAMS' FB page.
  • Mark Gray So you baited up two tiger sharks and they didnt bite the bucket you had your wetsuit wrapped in...........is that the science your using?
  • Shark Attack Mitigation Systems - SAMS Mark, our response to your other post on the site today refers. To clarify, the one minute video sets out one very short extract of a complex testing process, which has been conducted independently by University of Western Australia since January. We welcome you to investigate the science in more detail. The link to which you have responded sets out the science page at the SAMS website, and the FAQ page at http://www.sharkmitigation.com/faq.html may provide more information if you would like to check it out.
  • Mark Gray So the research hasnt involved Great White Sharks? Bit irresponsible in Marketing your products and stating that they "Protect" and "hide" without testing on the major species of sharks which has cause the fatalities in Australia in recent years..........?
  • Shark Attack Mitigation Systems - SAMS Mark, we are trying to come up with a positive solution, based in science. Independent testing will be an ongoing process, potentially taking many years as we discover how the full range of predatory species respond and progressively refine the visual technology. All ocean users are at risk and discretion and caution is always necessary. We think people know that. We are offering information on what we have found so far scientifically, and an alternative to a black neoprene wetsuit so that ocean users can consider that option and make a choice. We are very clear that we are not offering guarantees. Who could? We invite you to also contribute positively to this page. We have responded to two of your posts already on the same theme. If you have suggestions as to how we could better inform, such as making the position clearer on our website or including more detail in our FAQ's then please let us know. We would welcome your constructive contributions.

  • Mark Gray Well according to your previous posting the testing program has only started in January this year with that testing program only conducted on Tiger sharks with baited drums???. Wouldnt it be wise and responsible to do further testing on different species, namely Great Whites and Bull sharks and using test subjects which honestly represent how your wetsuits present themselves to potential predator shark (ie moving dummy surfer or diver)? With all your press releases and your youtube clip you refer to your products as "Protecting" or "Hiding" from a potential shark attack and base all your supporting evidence on a test which produced very limiting results. You have entered into a full scale marketing event without doing your homework on the so call technology and the testing involved. Now if you can not answer my questions from my own experience with sharks on a regualr basis and with little common knowledge well maybe you have a take a reall good look at your product and how your market it and yourself to the community and consumers. I have asked in a previous posts questions which I and I bet alot of others out there would be asking and the last response I recieved from you was to quote "Mark, we note and respect your perspectives and views" but failed to answer the questions at hand.
  • Mark Gray I accept your invitation to contribute positively to this page. What I would like to see is some more transparency to the technology, research, and what you conveyin your marketing of your products to the general public. I would like to see these 10 questions answered: 
     1. When did the in field testing start?
    2. When did your marketing campaign start?
    3. Has there been any testing of your wetsuits on Great White and Bull sharks?
    4. Has there been any other testing procedure which has not included baiting of sharks for attracting? If so what have they been?
    5. Has there been any testing which involved moving a simulated subject wearing you wetsuit through the water (both Diving and Surfing)?
    6. What in field testing program has been used to determine how Cryptic your wetsuits are? And how are the results differ with different visibility, water colour, overhead light ?
    7. Are the Cryptic dive wetsuits loose their ability to “Hide” when a scuba tank, BCD and fins are added?
    8. How does the Cryptic dive wetsuit hide the noise and sight of the bubbles of a scuba diver?
    9. Has the results of the research conducted by the WA University been published and if so which publication?
    10. Do you personally wear your SAMS wetsuit when your diving or surfing?
  • Shark Attack Mitigation Systems - SAMS Mark,

    Responding as follows:

    1. When did the in field testing start? January 2013 – refer previous post.

    2. When did your marketing campaign start? We have not started marketing, we did a media release to let people know what we are doing on Wednesday last week, and opened up the website for review, together with this Facebook page to encourage discussion.
    3. Has there been any testing of your wetsuits on Great White and Bull sharks? Not as yet, we have covered this in your earlier posts and elsewhere in the forum. The next set of tests are proposed to be with Great Whites.
    4. Has there been any other testing procedure which has not included baiting of sharks for attracting? If so what have they been? Not at this stage, the University of Western Australia is precluded from using humans or humanoid forms of any kind and have determined that the existing testing process is satisfactory. Baiting is a necessary practicality to get any engagement with sharks in experimental conditions.
    5. Has there been any testing which involved moving a simulated subject wearing you wetsuit through the water (both Diving and Surfing)? Not as yet.
    6. What in field testing program has been used to determine how Cryptic your wetsuits are? And how are the results differ with different visibility, water colour, overhead light ? We have responded to this question elsewhere on the site yesterday and will include in our FAQ’s at our website.
    7. Are the Cryptic dive wetsuits loose their ability to “Hide” when a scuba tank, BCD and fins are added? We have responded to this in your previous post.
    8. How does the Cryptic dive wetsuit hide the noise and sight of the bubbles of a scuba diver? Obviously it doesn’t.
    9. Has the results of the research conducted by the WA University been published and if so which publication? We have responded to this in the posts above.
    10. Do you personally wear your SAMS wetsuit when your diving or surfing? Yes.

    Mark, you have now posted somewhere between 20 and 30 questions to this page in the course of a couple of days, most of them repetitious. Some include personal statements that verge on troll-like behavior. We have respectfully attempted to answer them.

    We accept that you are not a fan of what we trying to achieve. Equally there are many people who see logic in the concept and wish to explore it further. Over the last few days, this has included previous shark attack victims making contact with us to see how they can help us in our trials.

    We will not be responding to any further posts from you, we hope you understand. If you continue to post in this manner we will, with regret, be obliged to exclude you from the forum.

  • Mark Gray its a shame that after you have invited me for constructive contributions in a previous post your now no longer going to response to my valid questions regarding your product. I am all for trying to achieve a much safer aquatic environment for all to enjoy but I am not a fan on the ways and means in which your company has mislead the general public by telling them that you are scientifically backed, have the technology which has proven itself, hides you from the shark when diving and putting the fear of god into the genral public especially in your youtube clip stating "now the deadliest coast in the world". You have based your whole product line on unfinalised research (Results from 6 months of a 24 months research project) and on a single species of shark which is not the major cause of fatal attacks here in Australia, under different conditions which would not apply for which your products are inteded to be used for. Your Youtube clip and media releases do not included any of the cautionary comments which you have included in you website and your response to my questions above show that your more concerned about getting your product out into the public eye well before any of the scientific results and conclusions have been finalised which to me makes me believe that your company is more concerned with making a quick buck and not addressing the public saferty of water users. Lie to the genral public and you will be bitten on the arse but my concern is more for the safety of potential users of your products who have bought your product based on your mistruths and false advertising.
 Mark has summed up his conclusions as follows.

 Mark Gray From the SAMS face book page they finally answered done of my point blank questions.

1. The field testing is a 24 month on going process which started January 2014. Final results are still 18 months away.
2. The field testing is based on one species
of shark (tiger) which was attracted by baits
3. The field testing has not involved Great White sharks or Bull Sharks to date
4. The field testing does not include testing similar sized subject which would represent the shape and movement of a surfer or diver. According to SAMS bait is required to attract sharks to the test subjects.
5. The cryptic dive suits are tested in clear water on a bright day not results given regarding low light, cloudy, or reduced visibility water quality.
6. Cryptic dive suits also require cryptic patterns to be also applied to scuba tanks, BCD, fins to make the wetsuit cryptic.
7. Cryptic dive wetsuits will not hide the user from the sight of their bubbles or the noise of their breathing.
8. SAMS acknowledged that GWS do attack using a breach method on silhouette prey on the surface.
9. SAMS also acknowledged that sharks also use other senses other than vision to hunt prey.

On the basis that field testing was performed by using baited drums on the test subjects of two tiger sharks in clear water in bright days with this testing only in its 6 month out of 24 set aside for a finalized conclusion makes me believe that SAMS is more interested at cashing in on the fears if the general public that spending time for proper ethical research to base their products on.

And to the Oceans Institute, this:

Sounds like your cashing in with the developers and using half truths to sell wetsuits that "Protect" and "Hide" you from all species of sharks. 
This is making your research look like as joke and is tied up with a bunch of snake oiler promising the world but delivering nothing

Bingo.
As I first mocked, and then stated: it's just total BS and shameless profiteering!

Meanwhile, in la-la land...
David has unearthed yet another priceless life saving  video by Eternal Youth Empire aka Israel-Light  - how to retard ageing by a whopping 30%!!!
And this time, it's all, gasp, for free!

Behold!



But beware!
You got to clean up the pineal gland, or it's all for naught!

Yes this is (caps lock) SCIENCE!
Exactly like her striped wetsuit - and incidentally, EXACTLY like the wetsuits by SAMS!

To be continued no doubt!
