Taiwan and Spain - again!

Albacora Uno - habitual Spanish poacher.

Read this.

Same old same old.
After having annihilated their own Fish stocks, Taiwanese and Spanish distant water vessels are now poaching in the Pacific - and not only them and not only there!

But in the end, it's also our fault.
For some reason I shall never quite comprehend, those nations are given a seat and alas, also a vote within the local RFMOS where they successfully prevent any sensible management measures, like at the last catastrophic meeting of the IATTC. And what is even worse, they are then even accorded fishing licenses where they then proceed to reap and pillage like they have always done, and this very much at the expense of the local fishing industry (and here!).

Huge kudos to the Marshals for having caught them red-handed.
And yes, They are protecting sharks and don't even have a reality TV show!!!

July: Fijian Bull Sharks!

Click for detail and save as to download!

Great!
The SOSF has posted its July Calender and guess what, these are our Sharks, photographed from the exact same spot where we placed Lill! Needless to say that not being one of the dreaded semis but a full-time pro, Peter Verhoog was awarded full honors - and no, his bodyguard did not scream like a girl, either!

Having said that, there was plenty to body guard!
The viz was absolutely dreadful, meaning that the Sharks were frisky and in yer face - very much to the delight of Peter but very much not to that of Tubee! BTW, this is a major cleanup job in Photoshop, so kudos to the photographer for both, the pic and the post production!

Do you like it?
If so, you can download it in lowest resolution from the top, or there are much higher resolution versions available here, along with the past months. And you can check out many more pics from the SRMR right here - stellar stuff!

Peter: Hartelijk bedankt!

Shark Shepherds - Diplomacy huh!

Good question!

Sometimes I hate to be right.
The Ueber-Angel's floating babemobile is on its way to Fiji (!) and somebody has had the simply brilliant idea to try and use the Fijian media to put pressure on government to reconsider its ban.
Same old same old - zero respect, just the usual shenanigans and strong-arm tactics, and this not in order to achieve results but merely in order to star, or whatever, in a sensationalist reality show.

From the article
The ship left Honiara yesterday for its Shark Angels mission in the South Pacific where it aims to help stop the killing and finning of sharks on the high seas...

So what about the assertion that
Hunting down shark finning boats was never part of the plan, and neither was the media involvement - just idle talk and outright lies?
This is not diplomacy and outreach; this has either been some pathetically amateurish attempt at disinformation - or it is the symptom of some major clusterfuck and messaging disaster where the laudable intentions of many are being highjacked by the megalomania of a few.
And the SA brand? Who cares - right?

Here's a thought.
When it comes to Shark conservation, both the Solomons and Vanuatu have nothing.
How about stopping there and doing some real, hard work. It'll take several years but what the heck - wasn't it about going where nobody dares to go, or whatever, for the Sharks?

To be continued no doubt!

PS: stellar post by Patric here!

Lill photographing Bull Sharks!

Great pic - and now you know where and how it was taken!

This is way cool, check it out.



The location is obviously the SRMR.
This is the lower pit is in 25m that we use as an alternative to the usual location in 15m. We go there in the off season when the Bulls are extremely shy, when there's too much surge and also, when the theromcline with the clear water is deep like after a lot of rain.

Great pics and surprisingly good footage, well done!
Despite being one of the dreaded semi-professional uw photogs (would you ever consult a semi-professional lawyer or MD?), Lill is really one of us and is thus sitting in the hot spot, very much with a bodyguard at her side - so don't get any ideas here, it's simply not gonna happen!
Just saying!

Enjoy Lill's video!

Shark Overpopulation???

Too many Sharks? I wish!

Really???
Did USP Marine School head Joeli Veitiyaki really say this???

For now, I'm assuming that the journo has made an error.
Maybe Joeli said something on the lines of if we don't stop overfishing, Shark populations will remain depressed, or the like.

At least, that's the hope.
But just for the record: the campaign aims at halting the precipitous decrease of Fiji's Sharks which would have devastating effects on marine ecosystems!
Apart from the truly remarkable event of witnessing a marine academic speak out against urgently required marine conservation measures, claiming that Sharks would ever overpopulate, or whatever, would reveal a catastrophic ignorance of Shark biology and of the role they play in their habitats, and of the most basic and fundamental insights of Ecology!
Sharks out-breeding their spawning prey??? And, what about predator/prey relationships, feedback loops, trophic cascades etc???
Really???

Protecting the nurseries?
Certainly, but this on top of a blanket protection of Sharks, this in order to protect them against incidental mortality when they reside in one of the most important hot spots!

So here's to it having been a mistake.
And: to seeing a correction in the Fiji Times!

South Pacific Projects - impressive!

Source.

Remember Alisi?

I just found her again right here.
Great to see that her advocacy for Sharks was not just a fad but that it is continuing even after the spotlight has moved on.
Kudos & Vinaka Vaka Levu!

The link alerts me to the SPP and I must say, I am impressed.
This is good local conversation, done smartly, consensually and inclusively and above all, quietly - just the way I like it and also, just the way it works! I invite you to explore that website as it is an excellent template for how things need to be done in Fiji, if not the SoPac in general.
And I also do like this!

Kudos!

Certified Shark Fins - redux!

The Shark fin trade - unsustainable and unmonitored

David's post keeps on giving!

Check out the comment by KT Tan at the end of the comments thread.
I'm being told that KT is a well known troll in the Asian press, and I should really not be feeding him - but his comments echo those by Carlie Lim of the HK Shark fin traders' association, and even those by the infamous Giam of CITES. It's crafty stuff that latches on to the bullshit propagated by what Sam calls verbose, passionate, on-line activists, and it cleverly mixes fact & fiction to weave a narrative of western imperialism and disrespect of Chinese culture.
Are we just gonna let it stand?

But worry not - I'm not gonna be suckered into feeding the troll.
Yes of course he is right about the bloody unhelpful generalization and hyperbole by the sharktivist fringe - but then comes a whole list of disinformation and rhetoric that has been brilliantly addressed and thoroughly debunked by Shark Savers here and here, so I really need not rack my brain for further clever rebuttals.

Where I want to go with this post is somewhere else.
Tan states the following
Ultimately, the moral/ethical question that arises is this : Should we eat shark’s fin soup at all?
My answer is that we should not if sharks are an endangered species, just like we do not eat whales, dolphins, tigers, elephants. bears, white sturgeons, snow leopard or panda bears etc.
Yup, and apart from not eating them, we should also not bloody buy products resulting from the poaching of endangered Tigers, Rhino, Bears and Elephants - right?

And since we're at it.
What about the bile of tortured Bears, or the meat of tortured or inhumanely killed cattle; or blood diamonds and gold that finance civil wars and genocide - and this irrespective of whether they were "legally" obtained from some murderous dictator or his militia! Or cocoa (= chocolate) and garments produced by child labor or in sweat shops - and this irrespective of whether child labor and sweat shops are being tolerated in the country of provenience! Or coffee and bananas where the growers are not getting a fair price - and this irrespective of whether the middlemen have purchased them legally! Or the products of the drug cartels - and the list goes on and on and on!
See where this is leading?

So what about those fins.
Yes the 500-odd Sharks are not all endangered - but it just so happens that the majority of the species whose fins are being traded are!
And let there also be no doubt that the only legitimate organization that assesses whether a Shark is threatened is the IUCN!
Certainly not CITES that is a politically and economically driven trade organization where several predominantly Asian countries have successfully prevented the listing of Sharks, this by "convincing" a minority to block the vote of a majority, very much like many predominantly Asian countries are undermining the decision making process within the RFMOs and using development aid to then go and reap and pillage in distant countries!

The facts are crystal clear.
Most Shark fisheries are being badly managed or not managed at all, and whereas it is correct to demand that the relevant countries must enact better management measures, it is never-the less equally correct to state that as long as they don't, one should not buy those fins. The same applies to fins that have been poached, or that have been traded through criminal cartels, or purchased from greedy middle men who cheat the fishermen - those fins should even be declared to be illegal. And the same definitely applies to fins that come from Sharks that have been cruelly finned, and from Sharks that are endangered!
That's got nothing to do with cultural discrimination - those are just the perfectly ordinary and increasingly stringent ethical guidelines of any trade, see the examples above!

And yet, the Shark fin trade remains completely non-transparent and unmonitored - to the point that one can easily purchase fins of GWs, and that shops and restaurants proudly display fins of Whale Sharks that have been obviously poached and traded in contravention of CITES Appendix II!
As long as that is the case, that trade needs to be boycotted - and where necessary, especially when there are criminal elements in play, it is perfectly legitimate that the authorities intervene with legislative bans!

Any good news for the traders?
Yes: there exist well managed and perfectly legal Shark fisheries!
I see no reason whatsoever why the fins from those legal and sometimes even reputable food fisheries for Dogfish, Thresher, Mako or the Sharks that aliment the appetite for flake should not be used for that soup!
Have those fins certified, document their provenience, brand them as sustainable and you may even succeed in selling them at a premium, much like, say, pole-caught Skipjack!

So here's the deal.
Prove that you're not exploiting poor fishermen or developing nations that don't have the means to properly manage Sharks and/or enforce their own laws; prove that you're not encouraging poaching and retention of live bycatch, and that you are not buying your products from criminal cartels; prove that you're not profiting from cruel, wasteful and unsustainable fishing practices!

That's the only way you will survive as an industry.
And if so, godspeed - and to your customers, as long as they really want to eat that stuff: bon appetit and enjoy your freedom of choice, individual predilections and cultural traditions!

And if not, face the consequences: the boycotts, the bans and the criminal prosecution.
The choice is yours.

Mary? :)

Sea Shepherd in the South Pacific?


First things first: read this.
The Fiji Blog is the official blog of Fiji's Ministry of Information.

What followed was a flurry of e-mails.
My friends being who they are, there was a lot of laughing, smirking and conspiratorial winking - so for the record: Beqa Adventure Divers have nothing whatsoever to do with that.
We are a foreign owned company and have no bearing whatsoever on what Fiji's government do and say. As Sea Shepherd HK's fiery Gary Stokes reveals, we limit our activities to feeding Sharks for money and to pursuing our ego-driven campaigns - and yes, we generally just stand on the sidelines and claim to be conservationists whilst having the audacity to critique others for actually doing something!
Well said!

PS! Gary has reached out & we're cool - I think. :)

Anyway.
What we did do, was to politely turn down a request by the SSCS for a few days of filming in the SRMR. As I said here, we want nothing to do with the dolphinization of Sharks, and we also certainly don't want to be in any way associated with Sea Shepherd's radical brand of conservation.
Having met him years ago, I don't like him much - but I do respect Watson for being one of the preeminent marine conservation activists. What I however hate are the personality cult, the hyperbole, the bullshit media, and the fanaticism and glaringly uncritical adulation by his devote followers - and let's not forget the simply atrocious poetry, barf!

Remember?
And if not...


Huge H/T to David!!!

Oh yes yes, I'm critiquing - again!

We were reinforced in our decision when a SSCS representative started making the rounds here in Fiji.
There was talk of an Animal Planet shoot, of two vessels coming here to hunt for illegal Shark finners, of roping in Ratu Epeli, of buxom bimbettes frolicking with Sharks etc. - in brief, some kind of Shark Wars, or whatever, combined with the usual self promotion by the Shark Angels, both of which I particularly despise.

But now, I read this.
Looks like someone has been listening, as this is really rather good, and kudos for that!

But is this the whole story?
You be the judge of that.



Well well.
Looks like nothing has changed after all.

I say, this is not the Pacific Way.
Nobody is asking anybody to put his life on the line (or was it, putting her life online? Detail detail!), and we down here have zero need for self-appointed deputy sheriffs, the more as this could once again lead to unwelcome political implications.
What we do require is intelligent, informed, committed and passionate people who help in advocating and then, implementing locally appropriate Shark management and conservation strategies, and this in a constructive, respectful and consensual way. This means hard, quiet and persistent work on the ground, and pursuing strategies that are diametrically opposed to Watson's interventionist approach.
This also means providing for resources for capacity building, monitoring, enforcement and prosecution - meaning time, talent and money and not foreign vessels playing policeman whilst starring for sensationalist reality shows.

Long story short?
Better change the playbook - or you'll be quickly celebrating the requiem for Operation Requiem!
My honest advice - free of charge!

PS: David - brilliant!
PS2: Patric on the Watson Doctrine & con-ninnies here!

And the saga continues...

Fiji - the End Game?

Bull Sharks in the SRMR - hopefully soon protected throughout Fiji!

Looks like it's crunch time.

A submission for the Fiji Shark Sanctuary shall be ready this month.
Then, Cabinet may approve it, or it may send it back for amendments, or for even more consultations like it has done last December. Please do check out the Fiji Shark Defenders page where you may, or may not be asked to lend your support.

This time, I am really hopeful.
Everybody including the Tuna industry has had a chance to state their views and I firmly believe that the Department of Fisheries is going to duly consider them in their submission.

And then comes the difficult part.
There will be a need for awareness campaigns, capacity building, monitoring, enforcement and prosecution - and above all, for finding the resources to pay for that all. The way I see it, the latter will very much depend on the exact wording of any decree. The more exceptions and loopholes it contains, the more people will cheat and the more difficult and expensive it will be to implement.

Keep watching this space for any further developments.
Fingers crossed!

China - monumental!


Wow.

Read this.
If the Chinese government has really decided to abolish the soup at its functions, there's a real chance that they may be swayed to get further involved in Shark conservation.
And if so, such a top down approach would be enormously effective, and this on a global scale.

Wow.

PS a few more details here.

Stefanie - fantastic!

Stefanie and the BAD boyz & girlz - click for detail!

Boy was I wrong!
I've once dubbed her a Bayrischer Rottweiler - but she's really nothing like it!

We've finally met and lemme tell 'ya, I am impressed!
I must say, Stefanie Brendl is one of the most humble, warmhearted and smart Shark people out there, a real Mensch - and boy, talk about somebody who really loves and understands the animals!
And is she determined like a pit bull? Most certainly - but in a nice way! :)

Anyway.
We had some great dives and some even better conversations, and everybody here cannot wait for her come back!

Bis bald Stefanie!

Rafting Whitetips?

In the footsteps of his dad: Tumbee in action!

Interesting hypothesis!

But is it plausible?
Having seen scores of Reef Whitetips ride the thermoclines in Cocos, I would not necessarily expect to find them resting in flotsam that is being swept across the Pacific; instead, I would expect them to elegantly ride out those currents to their ultimate destination, like I've seen them do many a time.
And although it is certainly plausible that some may get swept away, I would not at all exclude that they may simply get the urge to relocate once their home reefs gets overpopulated, and therefore catch a passing current on purpose.

But that's just detail.
All-in-all, this is really cool research - kudos!

And talking about fishing the Commons...


The current solution to avoid a Tragedy of the Commons where both the eco-system and consequently the fishing industry collapses, is a total ban on all fishing of sharks and any sale of shark products regardless of whether they are accidentally fished or not.

Paradigm Shift required!

Shark finning bans - not good enough!

And I cite.

The purpose of the post is to educate those individual activists and small organizations who create “awareness” videos that do not have their facts straight. I’ve come across too many of these to count in recent weeks, and “spreading awareness” of the wrong facts doesn’t help.

Finning Bans?

Indeed!
The myth-busting continues - after deconstructing the oxygen myth, David has now finally set his sights onto those frustrating anti-finning petitions and media.
Or maybe I'm too optimistic and he hasn't and just wants to educate everybody about the correct terminology. Be it as it may, this comes on the back of this rather epic quiz by Angelo and needed to be said.
Well done.

And before you get all worked up.
No I'm not pro-finning - on the contrary!
It is an ethical abomination and needs to be banned - but what I'm saying (read it!) is that in itself, it does not save Sharks: instead, it needs to be part of a whole package of Shark conservation measures.
Believe it or not, finning bans are a concept from the 80ies, and they have proven to be largely ineffectual in reducing Shark mortality. And by only asking for finning bans, we are actually detracting from the real issue at hand , i.e. that way too many Sharks are being killed.
Depending on where we choose to position ourselves in the ideological conservation continuum between Shark huggers and Shark fisheries managers, what we got to ask for are either full Shark fishing bans or at least, that Shark fishing quotas be fully sustainable.
The latter mandates that quotas be a fraction (I hear, approx 30%) of recruitment, that finning be prohibited, that bycatch and other impacts like habitat degradation be greatly mitigated, etc etc. - and yes, going back to the comments thread in David's post, I also believe that dumping the carcasses of landed Sharks should be penalized in the same way as illegal finning because in real terms, it is the exact same thing!

Fin Bans?

And what about those fin bans?
I must say, I am quite enjoying the brawl spirited discussion in the comments section of David's post! :)
Personally I believe both sides to be equally right and wrong, and this is why.

There are fin bans and fin bans.

The first one was Stefanie and Senator Hee's historic ban in Hawaii.
The state had already banned all Shark fishing but there was a loophole whereby Hawaii was acting as a turntable for the Shark fin trade, and this measure was meant to close that gap.

So, was that a good thing?
I fully agree with David's listing of the appropriate Shark management tools, and I cite.
  • Special protections for particularly threatened species
  • Species that aren’t particularly threatened fished according to a science-based quota
  • Appropriate bycatch reduction strategies, including gear restrictions or time/area closures
  • Appropriate reporting and enforcement.
But that may not be the full story and when viewed on a global scale and in a real world, it may also be a bit naive.
Hawaii is an important tourism destination and may have decided to ban all Shark fishing in order to fully preserve its marine habitats but possibly also for cultural reasons and in order to market itself as an ocean-loving destination or the like - and whereas that decision may not be fully rational from a scientific perspective, it is certainly legitimate. Same-same for the decision not to facilitate the global fin trade that is presently totally non-transparent and unsustainable.

My only personal caveat, if at all.
I don't like generic food bans whereby some people arrogate themselves the right to tell others what to eat. Assuming that there could once be a certified Shark fin soup, and that it would not constitute a strong public health risk (which in the US would be for the FDA to ascertain), I would have advocated an according exemption for those fins - e.g. fins from these certified Spiny Dogfish where at least Chuck appears to say that the certification is legit.
But I'm clearly splitting hairs here - so yes, I do like the Hawaiian fin ban.

And I do like the fin bans in those Shark Sanctuaries.
There, several states and countries have taken the decision to ban all Shark fishing, this preeminently because of concerns for their marine habitats but once again also for ethical and cultural reasons, and often also because it is good for tourism.
The fin bans there are part of a whole array of measures and have another purpose and that is, to facilitate enforcement. The rationale is that instead of squandering scarce resources in trying to apprehend every illegal vessel and fisherman, one can concentrate efforts on the bottleneck, i.e. the comparatively few traders that process and export the fins - and a possession ban is the cheapest and most effective means of of achieving that aim.

But once again, I do have a caveat here.
These are stop-gap measures aimed at achieving an immediate result in the most effective and efficient way possible. But as I never tire to say, I am firmly in favor of sustainable fishing (and hunting), and this of any animal including Sharks.
There are now more than 7 billion people (and this!) and like it or not, they want to consume protein. Those are the facts on the ground and farming (aqua- and not) is not the only solution as it, too, carries severe ecological consequences. As an example, approx 43% of Earth's land has been converted to urban and especially, agricultural landscapes with much of the remaining landscapes reticulated with roads (Nature, June 2012), exerting incredible pressure on terrestrial biota. We cannot possibly want more of that can we.
Where I come from in this, is that reality on the ground dictates that there be a mix between farming and wildlife extraction, but that the latter must happen sustainably.
With that in mind, I would certainly not oppose a fully certified, fully sustainable food fishery for Sharks - but only once the fishermen have proven that it is sustainable, see the last point in this post!

And those fin bans in the US states?
I've frankly stopped bothering after California - but without knowing the minute details, here's why I don't like them much.
From what I've been told, I understand that the principal aim is to cripple the international Shark fin trade. That in itself is a legitimate cause, the more as the global trade is certainly totally unregulated and unsustainable.
The problem I see, is that the ban impinges on three different sets of fins:
  • those unprocessed fins that transit the US on the way to Asia where they will be processed for consumption.
    Yes there are a valid ethical reservations whereby we can choose not to facilitate an unsustainable animal trade - still, my question is, does closing down the route through the US really save Sharks? Will less Sharks be fished as a consequence, or will the fins be simply re-routed elsewhere?

  • processed fins that are being imported into the US to serve as ingredient in the Shark fin soup.
    Once again, I find banning them OK as long as those processed fins derive from completely unregulated and unsustainable fisheries - but I would have welcomed an exemption for any certified product, something that does not exist now but is at least conceivable in the future.
    And does this save Sharks? Certainly not directly as the Sharks have already been killed somewhere else - and when it comes to the argument that it reduces global demand and thus the pressure on Sharks, I remain highly skeptical.
    What percentage of total demand does the demand from the US represent, and does closing down that specific consumer market have any incidence whatsoever on global catches, especially in a supply limited fishery?

  • fins that come from Sharks that have been legally caught in the US and specifically, in the state that is banning possession. Yes there may be also illegally caught fins and if so, their possession is already banned and not the topic here.
    But how can it be good legislation to continue to allow that Sharks be killed, presumably because in the opinion of the legislator, the fishery is well managed, but to then demand that their fins be thrown away? It leads to the absurd outcome that somebody may legally consume, say, legally caught Thresher Shark steaks but not a soup made with the fins of that same Shark.
    Would an exemption for legally caught local Shark fins not have been a much better solution and avoided the tricky question of whether the bans are racially and culturally discriminatory?

  • And since we're at it: the fines are just ludicrous - at least in some states, like $ 100.00 to 1,000.00 in California! It would have been much better to have much higher base fines plus a mandatory additional fine that is equivalent to the value of the fins in Asia - but I hear that this has been recognized and that later legislation is taking it into account.
All-in-all, this is just poor legislation: poorly thought through, sloppy and rushed, and I can understand why David doesn't like it. But it's at least something which is probably better than nothing at all - though clearly worse than something real good!
And yes I do also understand that this is a political process which consists in pursuing realistic goals and accepting what is possible!

Long story short?
  • On a global scale, Shark continue to be killed at unsustainable rates.
    This is essentially due to poor management, often meaning a lack of management plans but above all, a lack of resources (and often also, determination) for monitoring, enforcement and prosecution. That's just how it is and when it comes to those developing and underdeveloped coastal countries, and the high seas, chances for improvement in the short term are close to nil.
    As long as that is the case, I strongly advocate the creation of large MPAs, Shark Sanctuaries and blanket Shark fishing bans - but this only as stop gap measures, so that Biodiversity and specifically, Shark populations can ark until conditions on the ground hopefully improve. That may take a very long time indeed and until then, those measure must stand.

  • But if so, let's abandon asking for finning bans and let's advocate Shark fishing bans and Shark trading bans instead!
    Let's not forget that the vast majority of countries already have finning bans, and that their practical effect in reducing Shark mortality has been close to zero, this also because of lousy enforcement!

  • When it comes to fin possession bans, they are sometimes an efficient and effective enforcement tool when flanked by fishing and trading bans. I also believe that as long as the Shark fin trade continues to be unregulated and unsustainable, there are valid ethical reasons to try and curtail it via fin bans - tho I remain skeptical about their ultimate effectiveness in reducing the number of Sharks that are being killed.

  • Some Shark populations are however well managed and there I do concur with David that bans are inappropriate.
    When there is good management in place, I am of the firm conviction that sustainable Shark fishing ought to be allowed, and this including the right to consume sustainably caught fins, local as well as imported.
    But for now, that's really the tiny, tiny minority of places - if at all! Most of the world is nowhere near as advanced as the US and possibly Europe, and wanting to apply the same parameters there is just simply hopelessly naive.

  • But maybe I'm wrong.
    Maybe we got to listen to Jimmy and especially, to Katrien who posted a great rant, I really enjoyed it! :)
    Maybe the overall situation is so bad that we got to forget the intellectual debate of what is appropriate and instead, just close our eyes and throw the kitchen sink at the problem, and hope that something will stick. With the other side embroiling us in never ending debates whilst continuing to slaughter the Sharks and running circles around those inept authorities, maybe we gotta start fighting dirty, too.
    Not 100% convinced that this is the right way forward - but I'm sure as frustrated as everybody else!
    But then again, progress has been impressive, too!
    It sure is complicated!
A Change of Paradigms

But whatever the situation, here comes the important part: we need a paradigm shift!

Contrary to the farmers that farm their own land, the fishermen have been exploiting the commons, meaning that they have been catching and making money off Fish that belong to all of us, often even thanks to subsidies the we all (!) have been paying for.
So far, the standard modus operandi has been that the fishermen have been catching whatever they could, and the track record shows that whenever they have not been curtailed, they have been overfishing recklessly, to the point that some of them have even managed to fish themselves into extinction. The result is that most Fish stocks have been severely depleted and may have even accumulated extinction debt.
Long story short: forget self regulation.

At the same time, the authorities have invested an inordinate amount of resources (for which we all have paid!) trying to manage that activity, by first paying researchers to go and collect all the relevant data and then, often when it was way too late, trying to fix the problem by managing (= reducing) the quotas and then investing more resources into monitoring, enforcement and prosecution etc.
My question is, are those investments adequately balanced by benefits (including revenues!) for all of us and is that the only and the best way to proceed going forward?

As Jimmy's comment in David thread illustrates, many conservationists including me harbor grave reservations against those fisheries researchers and managers.
There is a lingering suspicion that those people are incapable of acknowledging the fact that they are presiding over the abject failure of their own past strategies, and that they will continue to cling on to archaic paradigms and continue wasting time and money on inefficient procrastination in the main intent of preserving their own jobs. Probably not quite accurate but having met many of them, certainly not completely inaccurate, either!
And whilst those folks continue to twiddle their thumbs, Fish stocks continue to be poorly managed and continue to decline!

But we simply cannot afford to waste any more time!I say, the conventional strategies have largely failed and we must find new ways to be more effective!
Let us invoke the precautionary principle and let us reverse the burden of proof. Let those who are making the money invest all those resources that are necessary for establishing adequate management plans, and let THEM prove to US that what they do is sustainable!
And this on all levels: let anybody involved in the fishing industry, from fisherman to trader to in- and exporter prove!!! that what they do is both legal and sustainable - and until they do, let's slash the quotas or ban the activity altogether whenever there is any reasonable doubt!

Yes it is radical - but does it make sense?
I believe it does and if so, let's start talking about it now!
Change will be difficult to come by, and it will take time, especially in the midst of this persistent recession - but if we want it we will eventually be able to achieve it!
The good news being that this will free scarce resources for the authorities to concentrate on monitoring, enforcement and prosecution, and to address the other threats to marine biodiversity, ie Global Warming, Ocean Acidification, Pollution and Habitat Degradation.

Anyway, please do read David's post and the comments thread - great stuff!
Plenty to think about - especially the part about changing paradigms where I passionately believe that it is the right way forward!

Enjoy!

Killing Sharks in Fiji!

Dead or dying Tiger Shark, note the everted stomach due to gut hooking - probably Malolo, April 25, 2012

Big Sharks are being killed in Fiji.

It's irrelevant who does it.
Right now, it's perfectly legal and singling out one person will not be helpful. Later on, the Mamanuca Environmental Society may want to go talk to him.

But the Fiji Shark Sanctuary cannot come soon enough.
Fingers crossed!

Greenland Shark - slow but effective!


Sorry for the protracted silence.

I'm mulling over a rather tricky post and we're currently hosting Shark conservation royalty - so please bear with me, all shall be revealed in due course! :)
But in the meantime, check this out.



That's one helluva slow Shark!
In fact, according to this article, the Greenland Shark may be one of the slowest Sharks around. Researchers have documented its speed at a paltry 0.7 mph, with tail beats lasting a full seven seconds.
No wonder Doug was not unduly alarmed!

And the notorious diet?
I don't believe for a minute that they actively hunt Polar Bears and Reindeer but rather, that they may have ingested those animals as carrion; but it now appears that they may prey upon arctic Seals that apparently sleep in water to avoid predation by Polar Bears - maybe not such a good idea after all!

But!
Do they then strip the skin in a in a corkscrew pattern ?
As far as I know, the wine has never been claimed.
Patric?

And what about this abomination?

Mimic Shark?

How bloody cool is this!

First record of potential Batesian mimicry in an elasmobranch: do juvenile zebra sharks mimic banded sea snakes?
Christine L. Dudgeon and William T. White

Abstract

Various forms of mimicry have been recorded in a large number of marine fishes; however, there have been no records of mimicry for any elasmobranch species.

We propose that the distinctly banded neonates of the zebra shark (Stegostoma fasciatum) are Batesian mimics of banded sea snakes (Elapidae).
Observations of banded juveniles of S. fasciatum swimming close to the surface strongly resemble banded sea snakes in colour and body form as well as the undulatory swimming movements. Sea snakes are venomous and are known to defend themselves against predators. Although several shark species prey on them, most species appear to avoid sea snakes as prey items. Juvenile S. fasciatum possess a very long, single-lobed caudal fin that remarkably resembles the broad, paddle-like tail of sea snakes. This may be an adaptation enabling this species to mimic sea snakes, at least in the earliest life stages.
There is a need for empirical testing of the hypothesis that juvenile S. fasciatum is a true example of Batesian mimicry, but here we provide evidence that suggests this may be the first example of mimicry in an elasmobranch species.

Yes so far this is only a hypothesis!
But is it plausible?

The paper offers a variety of good reasons, and here's the picture from the paper that I find totally compelling.

Fig. 1. Colour pattern changes in Stegostoma fasciatum: (a) 40.5 cm total length (TL) newborn from Bahrain (photo: J. Randall); (b) 58 cm TL from Bahrain (photo: J. Randall); (c) ,220 cm TL adult from northern Australia (photo: CSIRO). (d) Newborn Stegostoma fasciatum swimming at the surface in shallow inshore, turbid waters off the Kimberley coastline of north-western Australia (photo: M. Pember); (e) a sea snake on the swimming on the surface in Shark Bay, north-western Australia (photo: W. White).

Wouldn't testing that hypothesis be the coolest Masters thesis, ever?
Here's a possible recipe, right from the paper.

Initially, it is necessary to isolate which of the banded sea snakes is/are the model species as well as which of the potential predators the deception is aimed towards.
It will then be possible to design experiments that test the behavioural and physiological responses of the predators to the model and mimic species as well as to target ecological and evolutionary data collection.
Whether juvenile zebra sharks are truly Batesian mimics of sea snakes and present the first example of mimicry in an elasmobranch remains to be proven; however, we believe that there is good evidence, as presented here, to support such a conclusion.

Any takers?
Fiji: we got the Shark and at least one Banded Sea Krait right here - and by the way, check out its tail: does it mimic the head?

Questions questions! :)

Pew: Australian Marine Reserves!

Deciphering Philopatry - good or bad Science?

Great HH with one of Neil's new tags.

Want to go and catch yourself some Salmon Sharks?
Nothing could be easier: go fishing in the Northern Gulf of Alaska in November - and bingo! And if you believe that the fishermen have not long discovered the TOPP tracks - think again!

As Juerg writes in his correspondence to Nature.

Two faces of marine ecology research

The ecology of animal movement is one field that would benefit from sound evaluation of the risks, benefits and ethics of its important research findings (Nature 484, 415 and Nature 484, 432–434; 2012 read it!).

Scientists can now track the complex horizontal and vertical movements of a wide range of marine species, including tuna, sharks and turtles. These results reveal biodiversity hotspots and inform conservation policies by providing insight into animal behaviour and ecology. However, they also guide fishing operations towards resource-rich locations — putting further strain on both target and by-catch species.

Too many species face severe stock depletion because of intense fishing, pollution and other anthropogenic pressures. The detrimental implications of marine ecological research results must be acknowledged.

But there is of course also this.

It is possible, by marrying electronic tag data with oceanography, to gain a sufficient understanding of ecosystem function to enable more effective management of ocean resources.
Specifically, this study shows that when bluefin tuna enter the Gulf of Mexico, they are going to specific locations, where cool, productive water in “cyclonic eddies” makes its way along the continental slope. So during April and May, when they are spawning, bluefin tuna are relatively concentrated – whereas yellowfin tuna remain disbursed broadly throughout the Gulf.

This suggests that it would be possible to protect the bluefin, which are accidentally caught on longlines intended for yellowfin, by restricting fishing in those specific areas where the bluefin are spawning; but that such restrictions need not reduce yellowfin catch rates since they are more uniformly distributed.

Or this.

Great white sharks are found in waters all around New Zealand. National Institute of Water and Atmospheric Research (NIWA), and Department of Conservation (DOC) scientists are investigating the long distance movements of great white sharks inside and outside New Zealand’s territorial waters to improve our understanding of their species’s migratory patterns.
It will assist with designing management measures to reduce shark bycatch in fisheries.

Niwa principal scientist Malcolm Francis said despite the process sounding rough, the safety of the sharks was at the heart of the project.
As part of a wider study which began in 2005, it is hoped the research would return population figures and migratory behaviour of the protected species to assess how many sharks were being killed in fishing nets and lines.

Yes it looks like we got ourselves an ethical debate!
But maybe not so much - and whilst you're pondering, here's a rather epic video about that GW tagging in New Zealand.
Enjoy!



So what about those tracks.
As Bob Hueter already stated in 1998,

I consider the issue of philopatry and natal homing in sharks to be the most important issue in shark biology today, and I challenge all shark researchers to test this hypothesis rigorously in their respective research areas.

Nearly every type of shark research can play a role in this, for the ramifications of philopatry, if true for most shark species, would be profound. It certainly would affect our views of shark evolution and genetics, and it would shape new perspectives on the physiology and ecology of shark species. It would fundamentally affect studies of shark population dynamics, and perhaps most importantly, it would drastically change conventional views of shark fisheries science for the management and conservation of shark populations.

Hundreds of thousands of dollars and thousands of tags later, we now know this.
Sharks and Fishes are not randomly distributed throughout the oceans. Instead, they frequent well determined seasonal, behavior-, gender- and age-related hotspots and travel between these focal points on well determined marine highways.
Or as Hueter and Heupel write in 2004 (read it, this is seminal stuff!)

Many shark species are highly migratory, some covering thousands of miles of ocean in a single year.
However, with the emerging evidence of philopatry in various shark species, it would be wise from a conservation and management perspective to not view this group of marine fishes as oceanic nomads, but rather as more sophisticated, long-distance travelers with a number of discrete homes in the sea. How precise those homes are will need to be established with further research and analysis.

For us Shark conservationists, those data about philopatry are absolutely vital.
As I've tried to show here, many Sharks continue to fall victim to incidental catches despite of being protected, something that can be countered by establishing seasonal localized fishing bans; and like in the case of Playa or, say Vietnam, those localized and seasonal measures may be easier to achieve than trying to enact blanket protection of a species year-round and country wide.

This I believe is also the next step after having established those Shark sanctuaries.
With the big announcement hopefully looming, we're consequently already mulling the next big project that is hopefully going to lead to the full protection of the Shark nurseries, and thus of the valuable big pregnant females during the birthing period.
Keep watching this space!

But what about those published tracks?
Are those publications, maps, interactive websites and apps not simply showing the way for anybody wanting to go and kill the animals? And there is of course also the Anthropogenic Allele Effect, specifically the possible impact of poorly regulated tourism on the animals once newly discovered hotspots are being publicized - like e.g. here!
Like Juerg appears to assert, I fear that this is very much the risk!

Solutions?
Like I said, maybe it's not that difficult.
  • Research and data per se are neither bad nor good; and if the track record is any indication, nobody is going to ever be able to stop scientific progress whatever the associated risks. That's just how things roll in science.

  • But the risks are real - re-read the examples in Nature.

  • Hence the inevitable conclusion, that whoever conducts the research cannot just disassociate himself from the possible consequences. Instead, it behooves the researchers to be fully accountable for their actions, and to be instrumental in mitigating the potentially negative implications of their queries. Obviously, this is easier said then done - but shying away from one's ultimate responsibility won't do, either!
But to come back to the topic of this post.
The data derived from telemetry studies (nice synopsis here!) are vital - but posting those tracks can only happen, if at all, with the utmost of circumspection.
It's exactly like in the case of Fish spawning aggregations where the ichthyologists have learned the hard way that it is better not to publish the exact locations: I say, unless there is unequivocal, robust and above all, fully enforced local management and/or protection, those data should be withheld and only shared with the relevant authorities and like-minded researchers, and this only in the aim of enacting adequate conservation and management measures.
And even once those measures have been enacted, it should be amply sufficient to publish large scale maps and keep the fine scale and exact GPS coordinates a secret.

Or am I missing something here?

A Ray of Light: brilliant Video by David!

David's new production company, Scarlet View Media.

I'm in love with Brad.

No not in that way! :)
But David's masterful portrait is so full of tenderness and empathy that one is instantly mesmerized by the guy's humanity and compassion, and by his selfless commitment to try and better protect the Sting Rays of Mallorca.

This is David Diley's coming out as a filmmaker.
Like Brad, he is achieving the seemingly impossible with zero back-up and minimal resources, simply driven by his passion for marine conservation and the need to make a difference by telling a story. I say, if this is a taste of things to come, the man is in for a stellar career!
Love the storyline, the filming, the editing, the style, the music!

A short film about Brad Robertson, a passionate conservationist tirelessly working to maintain and grow a grassroots, community based project to help protect the Stingrays of Mallorca.

This is the reality behind "spit and sawdust" conservation, there are no glossy marketing campaigns, no sexy photo-shoots and most critically of all, no financial support, just Brad and his wife Bea, struggling against bureaucracy, apathy, crippling financial pressure and a lack of support from the people who could actually help.

The economic crisis has had a devastating effect on Spain, a country which has cut funding to support the policing of its Marine Reserves by up to 80% and as a result, we see that without vigilant protection, a "Marine Reserve" is no more a haven for marine wildlife than any other stretch of unprotected coastline.

So why does he bother? Because he's a diver, a diver who wants future generations to experience the kind of things he has in his twenty years underwater, the kind of incredible experience we see at the climax of the film an experience which illustrates just how important Brad's work in Mallorca is.

Enjoy David's video.
