Shark Attack Horror?

 
Really - have you seen this shit?
 
Andrew is obviously totally correct, the comments are total rubbish.
He was cornered by an eager "reporter" and like we always do lest there be any misunderstandings, asked that any questions be sent to him by email.
Alas, that obviously never happened.

So there, let me try to put things into context.
  • First and foremost, Mark is apparently going to recover OK.
    He's a real nice kid and we wish him the best of luck and a speedy recovery.

  • He was however not merely free diving, he was spearfishing.
    As shown in literally countless examples, this can frequently lead to shark bites. Like I said many times eg here and here, it is well known that the Sharks in popular spearfishing locations like Frigate Passage can get highly conditioned = aggregate at the mere noise of a speargun being fired, get highly excited by the vibrations of a speared fish, try to nab any catch and retaliate when poked and pushed away. This is most likely what has happened here.
    In brief, do not fight with a Shark over a fish!
    To cite myself (talk about being prescient!)
    And if you spear fish and are not careful, you may well end up having one of those close encounters described by Jonathan - not because of us but because that is what happens everywhere around the world, see here and here among many, many such examples!
  • The Shark was most likely a Grey Reefie.
    But it could also have been a Silky (no that's not a Bronzie - nor is this one!) or a Galapagos - case in point here! Bronze Whalers however are essentially antitropical and not officially recorded from Fiji.
  • The Shark feeding dives have nothing to do with this, zero.
    Once again, we have actually collected the scientific evidence that clearly illustrates that with the exception of our small harmless Whitetip Reefies, our Sharks
    a) were never resident but have instead always spent most of their time roaming throughout Fiji, and most importantly,
    b) have never depended on our handouts but have instead remained wild animals that have always continued to normally hunt their prey away from the Reserve.

    In brief, the fact that we feed less (yes we do still feed) has no incidence whatsoever on the well being and/or the behavior of our Sharks = they are not going hungry nor being more aggressive nor roaming further afield or anything like that - and again, this is not my opinion but evidence = fact!
    Read the links!

    And one more thing.
    Some quarters have suggested that our fed Sharks may have lost their natural fear of humans and may therefore have become so-called beggar Sharks and thus, more dangerous. We do not observe any of that when we dive without bait in the Reserve, and it thus makes no sense whatsoever to assume that it may be happening further afield.

    Again, the people who have conditioned the Sharks to approach spear fishermen are not the Shark diving operators but... the spear fishermen themselves!
  • And no, this is not about testing let alone predation!
    Those smaller Sharks simply don't prey on humans. Instead, the bites are most certainly agonistic = due to competition and/or aggression and/or self defense/retaliation - read this about agonism and this about Shark attacks.
There you have it.
In brief, Fiji's responsible Shark feeding operations have zero effect on the safety of the population at large - re-read this.
 
Long story short?
Sadly, this is nothing more than shoddy journalism that instead of bothering to engage in even the slightest modicum of objective research and fact finding, is merely repeating some random unqualified and unsubstantiated speculation and hearsay. And by being unnecessarily sensationalistic and misleading, it contributes nothing to the safety of the public and is also bad for the Sharks.
Not impressed, sorry!

Better next time Fiji Sun!
 
PS: really interesting comments section here = note how there's none of the usual gratuitous drama. And Setareki's reminder of the ubiquitous poaching and illegal selling is obviously spot on. Like I said back then, we know the perpetrators and also the enablers, and there will be a reckoning.

PPS - Bingo: watch this - fundraiser here.
Having actually gone and asked Mark
  • He was indeed spearfishing

  • It was indeed a Grey Reefie

  • The Shark was exhibiting the typical agonistic display of this species and then attacked twice, as they do. This also tells me that it was probably not a tourism Shark as those are used to people approaching them and have never, ever displayed agonistically during any of our feeds.

  • And finally, beware of the charlatans and self professed experts on social media - really, what a sorry bunch of total losers!

Ralph Collier - quousque tandem?


Oh FFS.
Read this shit.

Yes he's still at it.
There has been a Shark attack on a surfer Shark encounter (right... I mean, seriously!) between a GWS and a surf board, and here they once again trot out California's token Shark bloviator.

Interesting.... possibly Coriolis?
Michael is of course totally correct: GWS taking up residency and establishing a territory that gets defended against conspecifics is just simply ludicrous. This was most likely a predatory attack or maybe, an unusually assertive display of agonism - tho we will obviously never know!

Where I differ with Michael is the bit about the respect.
I ask, respect for WHAT? The serial pear reviewed pseudoscientific garbage? The denialism? The quackery and credulous pseudo- and anti-medecine? The shameless and callous conspiracy theories? The demented NRA garbage? The xenophobic fearmongering?
And check out these links

Respect?
Nah, not from me!

Pioneering DNA Shark Research Methodology?

Source.

Have you seen the above - impressed?

Me, not so much.
I don't know what planet those dudes are living on - but both we and all Shark researchers I've ever talked to take DNA samples with a simple biopsy probe that can be deployed underwater via Hawaiian sling or spear gun (or even a ROV!), or from the boat via a lance, etc. As tested multiple times, e.g. here, the methodology is highly innocuous and leads to zero post-impact mortality.
Those probes have been around for decades, and contrary to what is being suggested, nobody has been hauling any Sharks out of the water and exposed them to potential injury that could result in serious health consequences and even death of the animal merely in order to obtain a tissue sample.
This is simple, proven research that needs no fixing let alone revolutionizing.

But maybe I'm missing something here.
If so, may I suggest to remove the highly misleading wording and replace it with some pertinent information.

Or not.
And if so... :)

Big GWS off San Diego - or is it?


And I quote.
When you see a picture like this one... you have to be weary, at first, of a hoax - but an EXPERT says, this one is far from it...
And though you and I may not be able to tell how big this Shark is from the picture, (the token owner of a demented dog and lover of large omnivorous plantigrades) can...
"The shape of this fin is very very suggestive of an animal that's in the fifteen foot range".
Wow!
But watch for yourselves - the man is truly a monster of erudition!

Or maybe, not so much.
Turns out it was an April's fool hoax, and that somebody had crudely doctored a pic of a dolphin, fooling not only Collier but apparently, a number of his colleagues - which of course begs the question, who else disposes of zero academic credentials but continues to publicly proffer EXPERT pronouncements about Sharks?
Lemme guess - the pompous bloviating fireman? The unequaled SVS?

Anyway.
Remains the issue of whether one can truly estimate the size of a GWS from the shape of its fin, a revolutionary technique that would spare the scientific community plenty of headaches and thousands of dollars in complicated and unwieldy laser equipment. When put to the question by Martin who incidentally happens to be the very person that uncovered the hoax, Collier indignantly lectures,

Wow - again!
Let's see... from apex to apex, would that be 55% or thereabouts - and if so, does that make me an EXPERT as well? 

But I'm digressing as always. 
So now, it's the shape, plus the distance between the fins - what, in millimeters? 
Cuz for the life of me, and much like those other laser toting ignoramuses, I could never tell the actual distance from looking at the pic at the top! But I sure can notice the glaring absence of a terminal lobe on the presumed exposed tail (compare to here, here, here and here!) - and thus, I will bravely go out on a limb and publicly call BS on Collier's assertion that he was right because actually, this is the superimposition of the image of a real GWS!

But then again, considering the historical precedent, who am I to say!
Opinions please: a) unfairly maligned EXPERT or b) pompous Sesselfurzer instead?

Baited Shark Dives and Shark Attacks?

Outright Shark feeding - even worse than chumming?

Oh well.
So much for being too busy to blog.

There has been a Shark strike in Western Australia.
From what I can discern, it very much appears to have been a predatory attack (Christopher???) and it comes right on the heels of Mr. Moore's decision to preemptively ban cage diving there. The apparent reason for that politically motivated stupidity was that South Australia had restricted cage diving there because Barry Bruce et al had discerned that berleying (= chumming) had caused a minimal change in GW distribution.
Nothing whatsoever to do with Shark attacks - but who gives a shit provided that one can engage in populist grandstanding, right? And this? Indeed: Neanderthal reactions!

Which brings me straight to the following.
I rather despise those couch farting Shark lists - but people do keep me in the loop about the rare noteworthy discussions; and so I got sent this remarkable, and provided that you got a sense of humor, incredibly witty post by the Grand Mufti of Shark behavior, non other than the forever unequaled Doc.
I hope he doesn't mind me re-posting it verbatim in all of its glory.

A key criticism of the ruling in Western Australia is that researchers were not able to show a causal link between shark attack and chumming at shark dives. Lets see how they might prove such a link using the scientific method. How about setting up two dive sites within say 5 km of each other. At one you use chum and feed the sharks from a feeding tube or box. At the other you attract sharks by low frequency sound attraction and again feed shark from some device that precludes odorant from getting to the test-beach 5 km distant.

Now if there are sharks around I wager they will very quickly be attracted to the baiting station due to currents which rapidly brings the olfactants to their nostrils---so you might get them trained up in just a few days. For the acoustic attractions the sharks have to be within about 500 m of the hydrophone and be fairly motivated at the time. This might take several months but eventually the sharks at both sites will be feeding regularly, and reliably but probably seasonally.

To be further certain about your experimental study population you would have to tag the sharks and possibly take genetic samples to be sure you are working with different animals at the two sites...ok it could be done. Thus you have established two relatively equal feeding sites with a control and a treatment trial....good!

So after about two years of preparations you can now set up an hypothesis: H0, the null hypothesis is that there is no statistical difference between the control and treatment groups with respect to shark attacks; H1 is the proof of the pudding---There is a statistical difference between the two.

Ahhh, but here's the rub: You would of course have to continue your trials until you collect and adequate sample size for your appropriate statistical tests that you would used to either accept or reject H1 or H0. Based only on the annual rate of shark attacks world wide, this will take on the order of 1,000 years depending on the seasonality of the sharks. Considering the paucity of attacks and the time required for a human generation, you should put in your will that for the next 50 generations your offspring must continue the experiment on a daily basis until each season ends, then start again next year when the season begins. Get my drift? So it goes for all such shark-attack research.

OK...I put it up there now you shoot it down. I personally would love to understand the motivation of why sharks bite naked apes. (see Gruber, S.H. 1988. Why do sharks attack humans? Naval Research Review 40(1):2-19.)

Bingo! :)
As I've said all along, those musings about Shark attacks amount to nothing more than conjecture, i.e. sometimes plausible but ultimately untestable hypotheses.

But is the whole story?
Is there really no evidence whatsoever to point us one way or the other?

I believe that in fact, there is.
Yes George the great doyen of Sesselfurzing should indeed finally creep out from behind his desk and have a reality check by doing a couple of Shark dives; but in this specific specific case, he may even be useful by staying right where he is, smack in the middle of his Sammelsurium of Shark attack data - and ditto for Collier!

What I'm suggesting is this.
Get a Masters student to mine those data and to analyze whether globally, there is any statistically relevant correlation between the location of Shark strikes and that of baited Shark dives!
Of course correlation, even if it were found, is not causation. And, this would not be testing the hypothesis that baiting leads to more Shark attacks. For that, one would have to proceed like Doc suggests and wait for several centuries. But it would at least give us an indication about whether the hypothesis is at least plausible and thus, worth testing!

Betcha the result it is a big fat zero!
And if so, wouldn't that be all the more surprising as common wisdom would suggest the exact contrary! Here's the long version of why this should be the case - but if you can't be bothered, here's the synopsis.

For there to be a Shark strike, a person and a Shark need to be in the same place at the same time (dooh...) and consequently, anything increasing the rate of such encounters increases the probability for such a strike.
When it comes to baited Shark dives, it thus follows that, equally trivially
  • the more Sharks are present, the higher the risk of a Shark bite
  • the more divers are present, the higher the risk of a Shark bite
  • the more dives are being conducted, the higher the risk of a Shark bite
  • the closer the divers and the Sharks interact, and the more frequently those interactions occur, the higher the risk of a Shark bite - meaning that protocols are incredibly important!
And then there's also the element of location, i.e. where those baited Shark dives are being conducted.
They are obviously being conducted where there are Sharks (dooh...) - but often, they are even located where Sharks aggregate naturally to mate and feed, e.g. around Dyer and Seal Islands in South Africa, the Neptunes in Southern Australia, Guadalupe, etc., meaning that those places are more dangerous to start with, something one may want to consider when analyzing the data.

But then again, maybe the above is a fallacy.
Maybe Shark dives habituate the Sharks to the presence of people, meaning that they become more relaxed or "tame" and thus refrain from biting. Let's not forget that agonistic (= essentially, defensive) behavior may well be one of the principal causes of Shark bites on divers! And if we put too many divers in the water, the Sharks may well decide to simply go away.
Yes as always it's complicated!

So how about it.
Will those guys finally let somebody analyze those data, and will those stupid assertions be finally outed for what they really are, nothing but rubbish and completely unsupported and probably even falsified by the very data collected by the people proffering them!

PS Patric here (thanks!) and Jillian here!
PS great comment on the attacks here!

South Africa: one Submission, two Petitions - and plenty of Hypochrisy & frothy Activism!

SA Great White by Dirk Schmidt

Well well.
Fisher's South African caper is attracting plenty of interesting chatter and activism.

First, we got ourselves not one but two petitions! Yay!
Both have been created, or whatever, by one Chris Hartzell, another one of the token Californian Sesselfurzer that found it fit to publicly fart some rubbish during the Junior controversy. His expertise: occasional cage diving in Lupe to heroically document animals slamming into cages - and I will certainly leave it at that, the more as like his expert pronouncements, those petitions are nothing more than hot perfumed air and will achieve zero as usual!

But there is also a submission.
Yes I've posted the link because I find it rather good, albeit in places unnecessarily argumentative - and no I won't go into detail as overall, it's a valiant effort that needs to be commended, the more as it appears to have elicited some interest by Dr. Alan Boyd.
From what I understand, Boyd is the person who ultimately controls all permits including those of the researchers and commercial operators and thus the big honcho man nobody in his right mind wants to start messing with.
Frothy petitioning or no frothy petitioning, the final decision in this matter will be taken by him - so it's good that he is at least considering.

My prediction: the circus will go ahead.
Fisher is certainly crafty and appears to have it pretty much tied down by having obtained the active support of the SA Government's Department of Marine and Coastal Management for which Dr. Boyd works, and by having successfully roped in a whole gaggle of local researchers for whom the double temptation of perceived global fame and money has obviously proven to be irresistible.
It's a big, well coordinated effort, it has already been set into motion, plenty of Sharks have been tagged and plenty of tracks are already being published, and I just cannot imagine that Boyd will pull the plug now that things are so well under way - but who knows.

On a side note.
Among the researchers, I hear, Ryan Johnson, Enrico Gennari, Alison Towner etc.

Ring a bell?
Yes those three are among the authors of this paper about the damage caused by SPOT tags. To be fair, the paper examines sub-adult GWs where rapid growth may compound the problem, meaning that the effects on the adult Sharks which are apparently being targeted now may be less drastic. But I also read this
the effects of removing large (>450 cm) white sharks from the water in order to deploy SPOT tags are still unknown and should also be considered.
Hmmm..

My personal call, so be it.
After what has happened in Lupe and California, I must say that I've come to equally despise Fisher's bombastic clamoring but also, the anal frothiness of the various SPOT tagging opponents.

Where I'm personally coming from is that I continue to hate the current technology.
For very personal and highly irrational reasons (= I love our Sharks) and very much despite of the following, I shall not enable any such research until the gizmos have been finally fixed.

But I must confess that I equally love the tracks and the insights that have been garnered from the tagging - and if they were perfectly honest, so do many of the detractors!
Having tried my best to educate myself and having had literally countless conversations (and heated debates!) with Shark researchers, I have been convinced that every one of them is acutely aware of the current misgivings and is honestly trying to develop better technical solutions.
But at the same time, the dire situation of global Shark stocks mandates that we find out as much as we can about their life history as fast as we can, and satellite telemetry is one of the most effective tools for obtaining many of those vital data. Depending on situation and species, this may well mandate the deployment of SPOT tags - and trying to decipher the multi-year migration patterns of GWs may just be such a case.

Fisher and his wandering freak show will move on.
But if Government and the researchers are smart (which is not a given!) and have read the fine print before signing away their life to crafty Chris, they will at least own the data that will hopefully result in new insights - and yes, hopefully in better protection as well!
Conservation of highly migratory species is obviously difficult - but as e.g. the GW research from the Eastern Pacific is revealing, there exist well defined migration highways and well defined activity hotspots and time frames, meaning that at least in theory, we can now concentrate on specific locations and enact seasonal fishing bans which is certainly much easier to achieve than blanket protection (Playa: hint hint...!).
The practical implementation will always remain the practical implementation with all of its many hurdles: but at least we are beginning to find out what will be most effective.

And in the specific case of SA?
I have no doubt that patterns will turn out to be similar - and who knows, now that Dr.Boyd is so much involved, may he even be developing a new appreciation of the resource he is tasked to manage? May he even become more accessible to the arguments of those who are fighting for the removal of the KZN Shark nets that are equally subject to the regulating power of the MCM?
Yeah I know I know... I'm now clearly faffing myself!

Anyway.
Kudos to Dirk Schmidt and against all odds, best of luck!

As always, we shall see shall we not!

PS exhaustive statement by Johnson/Fisher/Boyd here - and I must grudgingly admit, rather compelling as well!

Sharks and Bears, no less!

Salmon-poaching and Bear-killing Sea Lion!
Oh for crying out loud! 
 
From the article
 “After Jaws, shark hunts increased and disrupted the balance of the ecosystem in a number of regions. In California, for example, seals and sea lions were able to thrive without a natural predator, leading to a depletion fish populations that eventually effected bears. It’s a domino effect.” 
And with those Shark hunts endangering Smokey the Bear, it follows that those wild fires would increase - and lo, they have
 
Beware of the dreaded domino effect! 
Q.e.d.! 
 
What can I say. 
Collier of SRI and SRC has already earned himself the uncontested distinction of having uttered this year's stupidest propositions - but this one must be truly the absolute, albeit I fear only temporary pinnacle! 
So there
  • There is indeed a correlation between declining Bear populations and declining Salmon runs (and here, etc)

  • The causes for the decline in Salmon on the West Coast are overfishing, habitat changes, hatcheries and hydropower, along with Global Warming. See here, here, here, here, here, etc. - no I'm not a Salmon specialist, I've just googled sockeye decrease causes.
    There is also evidence that pinniped predation does in fact effect already depressed populations of Salmon - but in fact, they are not the cause for that depression, they affect the recovery!

  • And the principal cause for changes in the population of Pinnipeds?
    Read this! = Sharks and Orcas do not have any noticeable regulatory influence on population size. In fact, since the protection of Great Whites nearly 20 years ago, the Californian population of Sea Lions has continued to grow! This because the people (not the GWs!) have stopped hunting them!

  • Long story short: there is ZERO correlation between Jaws and starving Bears!
But who cares about facts - right? 
Facts are booooring!  
 
 
PS - and how about those Chinook-eating Orcas
Are they killing the Bears, too - or are the Sea Lions killing the Orcas, or what??? 
Damn domino effect! 
 
 HUGE hat tip to that, and I cite, deplorable, self-centered, self-absorbed, egotistical, hate mongering, ignorant, insecure, piece of crap with very limited brain power and little to no social skills!

Juliet - excellent Job, again!


I must say, I'm increasingly impressed by the rather formidable Juliet Eilperin.

I first noticed her promo video and now comes this article in Foreign Policy.
Like Richard remarks, it is refreshingly factual and devoid of the usual pathos and hype, and this in spite of the difficult topic, the recent rise in reported Shark attacks. This is excellent, well documented and highly erudite journalism for which she needs to be commended.
Required reading - and BTW, what a monumental difference to the usual pathetic explanations by the Sesselfurzer!

Incidentally, I've also just finished reading Demon Fish.
More about it later but for now, only this: the praise is well deserved!

Kudos!

Shark Feeding Rubbish from Down Under!


Here we go again - and yes, I am livid!
I was having a real nice, mellow day - and now this.
This is what you get when moronic reporters, or whatever, interview moronic Shark experts!

No, I'm not gonna bother to post a full exposé.
I've blogged ad nauseam about feeding Sharks and I would be totally wasting my time trying to formulate yet another novel response to the old tired moronic allegations.

So this time, let's do something different.
Please re-read this.
Then, re-read this.

Then, have a look at this shit.



See?
The token Sesselfurzer (no, not a PhD!) has released a few more farts.
And then we got ourselves a veritable diving underwater medecine expert, Dr Carl Edmunds (Navy School of Underwater Medicine and South Pacific Underwater Medical Society) - who has been personally diving in the SOPAC no less! Wow, talk about impeccable credentials - after all, a PhD is a PhD, and who gives a shit about the totally irrelevant detail of the discipline it was obtained in! Tell 'ya what: how about an even more impressive veritable diving PhD (!) in quantum physics (!) next time!
And how about Mr. Hoy himself asserting that keeping (and feeding!) Sharks in an aquarium is a hell of a lot better for the Sharks! Compared to? Obviously, free Sharks being offered the occasional snack!
Just Great!

I say, show me the F@$%ing Evidence!!!
Are there more Shark attacks on Flinder's Reef?
Have there been less Shark attacks after the Florida ban?
Right!

Notabene: the above obviously with the exception of Pensacola where the life guards will henceforth be able to avail themselves of the unparalleled (!) spectacular eco-behavioral insights of the world's ultimate Shark expert, ladykiller (for German groupies only - alas!) and I read (!), owner of Sharkwater, Erich Ritter!
Talk about a prudent and at the same time, highly effective and outright visionary investment of taxpayer money - especially now in the recession!
How cool is that!

But!
Did I hear
There were reports of increased activity around the beaches, including reports of Great Whites circling fishing boats waiting for food?
Indeed! How many fishing boats are dragging in struggling Fish that send around irresistible vibrations all across the ocean? How many fishermen standing on the shoreline which last time I looked, includes the beaches drag in struggling Fish that send around irresistible vibrations all across the ocean? How many spear fishermen operate close to shore and shoot Fish whose death throes send around irresistible vibrations all across the ocean? And, how many of those folks clean their catches, throw the scraps into the ocean and create irresistible chum trails in the process - and this always in the same place, like the entrances and inside of the harbors and marinas? Remember Walker's Cay? Hell, in Hawaii they even conduct Tiger Shark viewing dives in one of those places!
Compared to how many Shark diving operators?

So who, exactly, is conditioning Sharks?
Let's ban all fishing and spear fishing!
I wish!

Have a nice day!

PS: thank you Patric! Rottweiler huh... :)
PS2: Wolfgang on the Sesselfurzer in 2007!

Undercurrent on Shark Feeding!

Yes we feed Sharks - Terry-fic pic by Terry Goss!

Gotta hand it to the folks at Undercurrent.
Starting with the idiotic title, they have managed to post the by far most preposterous piece of utterly stupid anti Shark feeding shit published by a dive magazine, ever.

WTF has happened?
What has possessed Ms Richardson to provide a platform for the ramblings of the anti industry zealots instead of trying to remain impartial like in the past? Tell you what happened: she clearly doesn't have the slightest clue about Shark behavior (poor innocent Cristina's Caribbean Reefs are not solitary but gregarious) or the Shark diving industry and its protocols, and is obviously increasingly believing and parroting what the clowns she is interviewing are feeding her.

Case in point, Ralph Collier.
No Vanessa, Ralph is neither a researcher, nor a scientist.
He is the prototype of what the Swiss call a Sesselfurzer, as in "someone who farts from a couch", very much reminding me of the Shark-hating voyeuristic parasite. His claim to fame is to head his Shark Research Committee (are there any other members?) whose only research consists in recording GW attacks on the Pacific coast of the US and publishing the statistics in a series of forgettable amateur publications. Like Ritter with whom he shares an affiliation, or whatever, to the SRI and the GSAF, he is the ultimate Shark pornographer who professes to be furthering Shark conservation but then ultimately reduces Sharks and their life history to one single aspect, that of Shark/human interactions, meaning Shark attacks.
Having been elevated to rank of "Shark expert" by the misguided invitation of the Egyptian authorities, he is now obviously basking in the limelight and being invited to run his mouth on topics about which he obviously doesn't have the slightest shred of knowledge, let alone expert competence.

What Collier spouts is not new.
It's basically a textual rehash of his interview on the atrocious Red Sea Jaws where he asserts that feeding Sharks will lead to attacks on innocent bystanders. The "proof": one single video showing divers hand feeding one single OWT with Fish stored in a fanny pack - which according to Collier has led that Shark to subsequently attack the hands and buttocks of two victims, leading the great researching scientist to derive a general rule pertaining to all Sharks in the Red Sea!
Howz that for taking intellectual and methodical shortcuts!

So we're looking at a shark habituated to human beings for getting food, and humans had taught the shark where the food was. And this occurred frequently in the Red Sea. With overfishing in the area, sharks have to come up to the reef area to feed, and now associate food with the human form. It's very much like training your family dog. When it sees your hand, it sits up to get a bite of that treat.

Right!
That's EXACTLY what trained family dogs do: they sit up whenever they see a hand (notabene, a hand that does not hold any food!), meaning all the time, and when hungry, they run out of the house and randomly bite the hands (and very possibly even the ass!) of passers by!
Which obviously begs the question, does Collier own a completely crazy dog - or may he be simply pompously bloviating without the slightest knowledge about the behavior of either dogs or Sharks.
You be the judge of that.

The rule is simple.
To know about the specific behavior of an animal, you need to observe that animal when it is engaging in that specific behavior, and this over an extended period of time. If you unable to do so (and I betcha that Collier's personal experience with Sharks is limited to maybe a few cage dives with GWs at best), you need to talk to the people who do, or read what they publish on the subject.
The people who feed Sharks and who observe Sharks that are being fed are some divers, several Shark diving operators and a handful of Shark researchers - and thousands upon thousands of fishermen and spear fishermen!

Surprised about the latter?
Fishermen do not only feed Sharks by presenting them baited hooks; many of them attract and often end up feeding Sharks when they drag in struggling fish and when they subsequently clean their catch and throw the scraps into the ocean. Spear fishermen are notorious for attracting, and even conditioning Sharks when they shoot fish and often find themselves embroiled in a competitive struggle over their prey. These people number in the hundreds of thousands and if anybody should be examined for possibly causing an increase of Shark attacks on the public, it should be them - not the few dozen operators conducting baited Shark dives!

But I'm not here to deflect and obfuscate.
I'm certainly not about to give you the spiel about how we, the Shark diving operators educate the public and contribute to Shark conservation, as it got nothing to do with the issue at hand. The issue at hand is whether divers feeding Sharks leads to an increase of attacks on people who do not partake in those events, like Collier asserts.
That is a testable hypothesis.

The first of the possible tests is simple.
A. Are there more Shark attacks on the public at or around Shark feeding sites compared to similar control sites.

Let me start with a pathetically trivial statement.
In order for there to be a Shark attack, a person and a Shark will have to be in the same place at the same time. Thus the incidence of attacks will inevitably depend on the following variables: the number of Sharks and the number of people present in a determined location; and also, the activity and behavior those people and the Sharks are engaging in.

With that in mind and considering that feeding Sharks will aggregate some species, one would indeed expect an increase in Shark attacks in the vicinity of Shark feeding sites - but when one analyzes the details, it is not quite that unequivocal.
In 12 years of feeding Sharks here in Fiji, we have witnessed
  • a staggering increase in the number of Bull Sharks that roam wide ranges but regularly visit Shark Reef once they have discovered that it's a good place;
  • a negligible increase in the number of the much more resident Greys, Whitetips and Blacktips, a species that does not roam and is thus not likely to be attracted from locations afar;
  • but then, a decrease in the number of intermediate Sharks like the Silvertips, Lemons and Nurses, and possibly even Tigers;
  • and with the exception of one single fly-by by a spooked Great Hammerhead, zero sightings of any other species, this despite of the fact that we regularly introduce 2-300 kilos of yummy bloody bait and despite being situated on the fringes of 300m deep Beqa Channel and of Beqa Lagoon that are all being prowled by a plethora of other Sharks like Zebras and Hammerheads but also pelagics like OWTs, Silkies and Duskies.
And what about Shark attacks?
There are only two Shark feeding operations in the country, Beqa Adventure Divers and the guys down the road, and we both conduct our Shark dives on the southern coast of Viti Levu facing Beqa Lagoon. Documented Shark attacks in the vicinity: a big fat zero, ever.
The few documented Shark attacks have happened in Taveuni where Tigers Sharks prowl the coast of the current-swept Somosomo Straights; in the mouth of the Sigatoka River where surfers insist on frolicking on a break despite of murky water and the occurrence of large Bulls and Tigers; and in various locations where spear fishermen have defended their catch, often at night.

Anybody wanting to venture a guess about the results from elsewhere?
More importantly, would any of the bloviating Shark attack experts please care to comb his collection of data in order to prove or disprove a causal connection? Maybe for once act like what they purport to be, forgo their idiotic ad hoc speculation and engage in the onerous task of following the scientific method instead?

B. What about the risk of Sharks biting people during Shark dives?

Let's go back to the above trivial statement and variables.
When it comes to baited Shark diving, the obvious, and equally pathetically trivial rule is this.
  • the more Sharks are present, the higher the risk of a Shark bite
  • the more divers are present, the higher the risk of a Shark bite
  • the more dives are being conducted, the higher the risk of a Shark bite
  • the closer the divers and the Sharks interact, and the more frequently those interactions occur, the higher the risk of a Shark bite
So, yes, unequivocally, Shark diving increases the risk of a Shark biting a person!
And the question of baiting versus non baiting? Yes, of course baiting increases the risk, as it draws in more Sharks and leads to closer interactions!
Duh!

The consequences? Please re-read this.
Some divers are happy to experience Sharks when and where they occur naturally. Others wish to predictably experience other species that are highly skittish and/or do not aggregate naturally and thus need to be attracted with bait. Assuming that baiting does not harm the animals, and so far, nothing indicates it does, it's not a matter of prohibiting baited Shark dives, it's a matter of ensuring a maximum of safety by adopting the best possible safety protocols!
Is there a residual risk - yes of course there is, especially for us in the front line!

But what about the motivation for those bites?
Please re-read this. It is, to the best of my knowledge, what we know about why Sharks bite people - and please correct me if you think I'm wrong.

With that in mind, I assert that nearly all of those bites are not predatory in nature.
Contrary to the plethora of bloviating Sesselfurzer, I look back on nearly 40 years of diving and on thousands of Shark dives, most of which in baited conditions. In all those dives with dozens of different species in different situations world wide, I have never been in a situation where I had the impression that a Shark was sizing me up as potential food, not one single time - and incidentally, everybody in the industry I have talked with shares the exact same observations.

I have however been subjected to multiple threat displays, this by Grey Reefs exhibiting agonistic hunch displays, by Silvertips becoming stiff and jerky and more recently, by large dominant Bull Sharks gulping and ramming me with their snout.

I have also witnessed several Shark strikes.
All but two were by Sharks biting the people directly handling the bait. All of them were characterized by one or more of these factors: competitive, frenzy-like situation; bad visibility; lack of concentration/distraction of the feeder; feeder being bitten in his left hand which was holding more bait; non-dominant, sub-adult animal barging in.
The two remaining strikes were retaliatory bites by Silvertips on people denying them access to bait, very much like the famous incident where a Silvertip bit Dinah Halstead in PNG.

Consequently, our procedures include the following
  • all divers wear dark full body wetsuits and especially, dark gloves as pasty white hands sticking out of dark wetsuits may be mistaken for bait, especially in low visibility
  • we maintain a clear separation between the customers and the Sharks
  • the feeders wear chain mail gloves to minimize the effects of accidental bites
  • we hand feed in order to always control the bait and to be able to withhold food once we deem that the animals are starting to behave competitively. In situations that become too tense, we temporarily interrupt our routine, retreat and wait for the animals to calm down again - which incidentally, they always do
  • the feeder is flanked by bodyguards monitoring any dead angles and gets rotated out after ten minutes in order to prevent lapses in concentration
  • there is only one feeder acting as the focal point for the animals, and he only ever holds a single piece of bait
  • we do not feed in bad visibility of less than 10 meters and are particularly alert when the visibility drops, as we have observed that this is when the Sharks (who do not see through murky water any better than we do) tend to be particularly edgy as they have to rely on their other, less precise senses when approaching the feeder
  • nobody but us approaches the bait bin, ever
Which brings me straight back to Richardson's stupidity.
It mentions two Shark attacks, that on Groh and that on Jimmy.

Jimmy was apparently bitten by a Caribbean Reef, a competitive, edgy and strictly piscivorous species, whilst handling bait in murky conditions. These to me are perfect preconditions for a mistake by the animal.

Groh was apparently positioned right next to the bait cage, meaning that the Bull Shark that bit him may have been engaging in behavior aimed at deterring a perceived competitor.
Furthermore, once the Shark destroyed the bait container and a lot of sand was kicked up in the process, it was trying to navigate in very reduced visibility and water saturated with fish juices, thus losing its sense of orientation and possibly mistakenly biting the first solid object it came across, i.e. Groh's leg. Was it really exactly so - dunno but it is certainly plausible.

And the Ritter attack?
The interpretation of what triggered it (= a stupid guy doing stupid things with macro predatory Sharks) keeps changing but to me, it's rather irrelevant anyway: this is clearly a predatory attack where the animal first tested and then devoured Ritter's calf.
Accident my ass!

C. Last query: are Sharks that are being fed by divers (and what about those that are being fed by fishermen and spearos?) more prone to bite people than unfed Sharks.

This is what Collier is asserting and Richardson is parroting - and of course what is being really asserted, is that fed Sharks will not engage in just any attack, but that they will be conditioned to perpetrate predatory attacks on humans.
This is of course a tricky one to document - notabene one way or the other!

There is of course no such thing as a generic "Shark" engaging in generic "Shark behavior".
Instead, Sharks are very different behaviorally both when it comes to species but to complicate matters, even when it comes to sex and age within the same species, all the way to pronounced individual character traits that can be shaped by individual experiences.
Also, the behavior of a species can be very different in different locations or at different times of the day, etc.

But having said that, I can share the following.
Our flagship species, i.e. the Bull Sharks that frequent Shark Reef have been fed for the past 12 years and are undoubtedly one of the most conditioned population of predatory Sharks on the planet.

Bull Sharks are very timid and hardly ever approach divers.
But we want our customers to experience them, and this is the reason why we resort to luring them in with bait, and to reward them whenever they approach one of our feeders in the way we like, i.e. from the left and slowly.
This is called training by positive reinforcement and I can assure you that contrary to all the pledges to the contrary that are meant to appease the tree huggers, all Shark diving operators feed the Sharks when trying to attract species that are shy and in locations where those species do not aggregate naturally. Teasing only just does not work long-term as the animals are not being rewarded and will simply stop coming.

It is thus fair to state that by feeding our Bull Sharks, we are conditioning them to approach people and thus engage in behavior they would not normally display.
But here's the catch: we observe that unlike Collier's demented family dog, our Bull Sharks will not simply approach just anybody: instead, they will only approach determined people, and this mainly only when those people are proffering food!

Example?
Look no further than when we are training a new feeder. For weeks on end, he will be standing next to the bin brandishing his treats - and the Sharks will look him up but never take a single bite! Talk about an exercise in total and utter frustration!
Eventually, a single animal who is very likely not one of the old-timers but instead a newbie who doesn't yet know anybody else will take a first offering and be forever linked to this one particular feeder. Only over time, some of the other Sharks will deign to come in for a snack, however really only when they have no other choice because their favorite human happens to have a day off.
Incredible - and yet, it's totally true!

Or here's another example.
I've been diving the Fiji Shark Dive since 2003, first twice and now, up to five times weekly.
I never feed the Sharks. What I do, is to observe and film them as part of our ongoing long-term monitoring. Over a very long period of time and by proceeding in very small increments, I have been able to attain a status whereby the Sharks appear to tolerate and at times largely ignore my presence, allowing me to roam freely among them without any discernible effects on their behavior.
But when people other than me or Rusi venture in front, the Sharks will inevitably retreat - unless we accompany them, and even then, their behavior will be decidedly more diffident!

And lastly, we observe this.
We frequently dive Shark Reef for other reasons, be it in order to service our moorings or because we are monitoring its health and changes in the composition of its population of Fishes.
The Bulls live deeper in the channel and when we don't carry any bait, chances of seeing them are extremely slim and limited to occasional fly-bys by single individuals. We have even mimicked the exact dive profiles of our Shark dives, as a control, and thus without any bait - again with the exact same result that the Bulls were simply not interested.

So much for the assertion that fed Sharks will approach and attack people - and this after 12 years of conditioning them to the presence of divers!

Granted, this only applies to the specific Bull Sharks that frequent the SRMR.
But until somebody comes and proves that a specific individual Shark that has been fed has increasingly attacked people in un-baited conditions, nothing will ever convince me that what I'm experiencing in Fiji does not apply to all Sharks that are being fed by divers anywhere!

There you have it, that's my take - thanks for your patience in trying to follow my rant.
Still think that Collier is an expert on Shark attacks in the Red Sea?

And what about Undercurrent?
Looking forward to reading Part number two - and very much hoping that Ms Richardson will start talking about the real problem that is besieging Sharks, i.e the global fishery targeting their fins! Not that I believe she will after this total fiasco.
But then, as they say, hope springs eternal!
