Tiger Beach - cool Research!


Hallelujah!

More pro-Shark features in the Florida press!
This time, it's a great article about Guy Harvey's research on Tiger Sharks in the Bahamas.

Yes, that would be "That" Guy, he of the T-shirts!
His bio mentions that Guy Harvey is a unique blend of artist, scientist, diver, angler, conservationist and explorer, fiercely devoted to his family and his love of the sea! And a real nice chap on top of that!

But much more than that, he is also the founder of the Guy Harvey Research Institute that is fiercely committed to the preservation of Fish and particularly, the big game Fish and Sharks. In fact, GHRI conduct some of today's most innovative Shark research and our Juerg often collaborates with them when doing his thing on Shark Reef.

And on top of that, he has done this!



Is this Guy cool - or what?

This time, Guy and his folks have gone to Tiger Beach to tag some Tigers.
It's a cool undertaking which aims at understanding the movements of those animals in the area - much like what we do in Fiji with our small-scale movement research. Whereas we feed the acoustic transmitters and sometimes attach them externally by using a spear gun, they rope in the Sharks and attach the tags internally. Not sure if I like that in terms of the stress they inflict on the animals - but it's fast, really quite harmless and they must have their reasons for believing that it's the best way to go.

And, it's for the best of causes.
Because as I read with great joy, it involves the Bahamian Government and has the aim to eventually have the area declared a Shark sanctuary!

Where did I hear that one before?
Great that things have been set in motion!

PS hat tip to Felix!

Guy Harvey Shirts - must buy!


It really is very very bad!
I spare you the links - but by now, the Gulf Oil Spill must surely have evolved into the worst anthropogenic marine extinction event, ever.

Action?
Have the US-based Marine Conservation orgs all re-defined their priorities and are they throwing their resources at this?
Hmmmmmm...

One that does is the Guy Harvey Ocean Foundation.
Guy being who he is has designed two new shirts and one poster that are now for sale everywhere. As he explains in his blog, fifty percent of the proceeds will go to institutions researching the effects of the spill. The data are vital as they will certainly determine the thrust of any future remediation once the spill has been contained.

Please go and purchase those shirts - this is really money well spent.
Thank you.

Shark Free Marinas PSAs!


Excellent stuff!
We've obviously been big fans of the SFMI since day one, and Fiji continues to be one of the initiative's principal supporters.

Ever since Guy Harvey and the Humane Society have decided to support the concept, Luke has been assisted by a growing number of Board members, Celebrities and yes, certainly not leastly, by the influx of much needed funds that are being spent on promotional and support materials but also, on excellent PSAs.

Here are two of the most recent ones.
The first contains the endorsements by actor Kelly Perine, singer/songwriter Aria Johnson , celebrity photographer Nigel Barker, actress Lisa Edelstein, guitar legend Slash, the Dr Guy Harvey, American football legend Steve Bartkowski and the SFMI's Director Luke Tipple.
The second features the unequaled Guy and specifically targets the marinas in Florida - and I sure hope that there will be more targeting the other coastal states where pro-Shark activities have so far been dismal!
And, let's not forget this one! :)

Enjoy!

55 dead Baby Hammerheads?

Shocking picture! But...

Please re-read Rick's post.
Did you notice the part about the moronic comments?
Case in point, yesterday's scoop by the GSCI - copy/paste.

The Global Shark Conservation Initiative 55 baby hammerheads, a full new generation, was lost because 1 man wanted to have the "fun to reel in" a big shark...

www.heraldtribune.com
The world-record hammerhead caught by a local fishing guide last month was big for a reason.

    • Jason A Creech The knee-jerk, human reaction to this kind of slaughter by those of us sympathetic to ocean-life, and all life for that matter, is usually anger and blame. This anger and blame is ineffectual and misdirected. Through activism and policy change the responsibility lies with us. There are always going to be shortsighted, pitiless idiots. We can wish them dead but wish in one hand and poop in the other and see which one fills up first. Act, vote, sign petitions. Anger is a gift.

Really?
Did anybody bother to read the article in the link?
Did anybody notice that the article is from 2006? It says it right there - twice!
How utterly embarrassing - and how revealing!

But Jason is of course correct.
It is not about who screeches the stupidest and loudest, it is about effecting change.

Here is what has happened since.
Bucky killed another record pregnant Hammerhead in 2009 and the ensuing debate motivated a few good people among which the Shark Brothers, Bob Heuter and Guy Harvey to embark on reforming game fishing for Sharks. The result: the Guy Harvey Ultimate Shark Challenge Tournament Series - where the very same Bucky Dennis is now practicing catch-and-release fishing for Sharks! I still don't like it - but it sure is a big step in the right direction and as always in real conservation, it is a pragmatic compromise and the result of much hard work.
Now, how motivating is it gonna be for Bucky to have his name dragged through the dirt five years after the fact and after he has voluntarily reformed the way he fishes?

And this is not all.
From what I understand, there is now a movement within the IGFA to abolish all-tackle weight records that will always result in pregnant females being targeted and killed. I am optimistic: if the gun toting trophy hunters have managed to outlaw killing pregnant females, so can the game fishermen who are increasingly advocating sustainable practices.

Plus, more good people have embarked on the arduous path of having Hammerheads protected in Florida - once again sans moronic screeching but with a lot of hard and persistent work on the ground. Here's the latest progress report with pointers about how to get involved - politely!

And the screeching activists?
I'd be lying if I said that I'm in any way surprised, or that I expect any improvements going forward. It is what it is and whilst those folks will continue to propagate their stupidities, others will thankfully continue working hard and hopefully (fingers crossed!) avoid being lumped in with the whacks, FINtastic and not.

And so it goes...

Thank You Sean Paxton!


Underwater Thrills alerts me to this op ed by Sean Paxton.
Please, do read it.

I must say, once again, I am impressed.
Like Guy Harvey, Sean and (Shark) brother Brooks are prominent and well regarded representatives of the recreational fishing guild and having people like them speak out in favor of Shark conservation is highly gratifying indeed. All these gentlemen have a proven track record of advocating and above all, implementing pragmatic and consensus based solutions like the Shark Free Marina Initiative and the Guy Harvey Ultimate Shark Challenge and having them on our side is simply priceless.

I was particularly intrigued by the reference to IGFA.
Whereas they have been brilliant in advocating tag & release for Billfishes, they remain equally appalling when it comes to Sharks. Certifying all-tackle weigh records for Sharks means that the trophy hunters will continue to specifically target the heaviest, biggest individuals which in the case of Sharks will always be pregnant females. Can you imagine a hunter willfully shooting a pregnant animal? Unthinkable! It's high time the IGFA took a stand against this wasteful, antiquated and ethically reproachful practice by introducing length records and advocating catch&release - and yes I'm repeating myself!
Many species will give birth in specific coastal locations, meaning that informed trophy hunters know exactly where and when to target them. The Florida legislation will be a great step forward in preventing just that.

Anyway, Kudos and Thank You to Sean!

Shark Tournaments - increasing Traction for Catch&Release Format!


Those game fishermen continue to kill Sharks.

But the tide is clearly turning.
Congratulatory reports like this one are thankfully disappearing.
Instead, the media are increasingly adopting a much more critical view by focusing on the ethical implications of those feats, or whatever and the plight of the animals that are being targeted.
This is specially apparent in the case of those horrible Shark kill tournaments.

Case in point, this article from Bermuda.
It bemoans the wanton killing of eleven Tiger Sharks (for Lobster bait?) and contains references to the Shark Free Marinas Initiative, the work of the Guy Harvey Ocean Foundation and the Ultimate Shark Challenge. All-in-all and despite of the appalling circumstances, this is excellent pro-Shark advocacy and kudos to James Whittaker for having listened to the right people!

And then, there is this post by the Consortium for Ocean Leadership.
Very unfortunately, it provides a platform for once again highly problematic statements by a Shark researcher, this time by one Lisa Natanson who appears to be a habitual groupie of the East Coast's kill tournaments.

Yes, taking samples from Sharks that have already been landed by fishermen is vastly preferable to lethal sampling.
But to then go as far as to become a vocal public apologist for the kill tournament format is totally unacceptable. Will those people ever learn to just keep a low profile, do their job and keep their mouth shut?
Thankfully, other more enlightened colleagues raise their voice in dissent

While acknowledging the scientific benefits that can accrue from tournaments, Dr. Robert Hueter of the Mote Marine Laboratory in Florida nevertheless believes that the pressures on sharks are too great for tournaments to continue.
“I’m not saying that we aren’t gaining useful data from this sort of sampling,” he says. “But scientists have been taking these sorts of samples at tournaments for nearly 50 years.
It’s questionable that the research benefits gained at this point justify the cost to shark conservation.”


Exactly!
How many more vertebrae does Ms. Natanson need to collect before waking up to the reality that Sharks are endangered and require protection and advocacy - especially by the people who research them? Will people like her ever overcome that apparent pervasive fatal disconnect between their research and the required ethical sensibility?
Yes, what may have been OK in the past is not OK anymore - how about some adaptive evolution!

Once again, kudos to Bob Heuter for having spoken up.
Having very much been part and parcel of the Guy Harvey Ultimate Shark Challenge, he knows what he's talking about and represents the future of Shark research, as do Neil and of course Juerg!
Well said!

Surprise!

Very dapper indeed! :)

Cool!

Photographer and Shark Expert Jim Abernethy thought he was getting some photographs and video of a blue marlin, but he wasn't alone.

Photographed in the Bahamas in May along with Guy Harvey and the Guy Harvey Ocean Foundation. For more on sharks and the problems they face, check out the new film, This is Your Ocean: Sharks.

Enjoy! :)

Excellent!


Please read this press release by Mote.
It really looks like the Guy Harvey Ultimate Shark Challenge has been a total success.
Kudos!

From an e-mail by a friend.

On a positive note, I went to Sarasota this weekend to the Guy Harvey USC...

I was able to watch Bob Hueter SPOT tag a young female great hammerhead. She was about seven and a half feet, so not exactly a baby, but maybe not quite sexually mature yet (they mature at @ 92 inches). Anyway, the shark looked to be in good shape when she swam off. Overall I'm really, really happy that I went...

Anyway I guess you can see that I was impressed.
Hopefully I'm not being naive or overly optimistic, but I really do feel good about this. I'm glad I got to see the hammerhead release, because that is one of the biggest concerns. This was a relatively small one. I know they'd like to tag a big pregnant one, so they can find out where they go to pup, etc.
I am still nervous about that, but definitely less nervous than before.


What a remarkable change!
Like me, this particular gentleman was initially skeptical and to see him so totally converted is truly remarkable! Good on him for having conducted his personal due diligence, and for having kept an open mind about the issue!

Me, too, I'm really impressed - so far!
Due to my personal distaste of game fishing for Sharks, I shall never quite warm to the concept.
But having said this, my hope is that this will establish a trend and that the existing kill tournaments will gradually switch to the catch and release formula - hopefully, without any new Shark tournaments being established.
If on top of that, the IGFA could be convinced to stop certifying those disgraceful all-tackle records for Sharks, then this would really be huge progress over the current status quo!

Fingers crossed!

Track your Tiger Shark!


This is way cool!
Gary alerts me to Mahmood's real time Tiger Shark tracks and I am deeply impressed!

From the website.
To understand tiger shark movement behavior in more detail and aid in conservation efforts, the Guy Harvey Research Institute/Guy Harvey Ocean Foundation and their project partners are investigating tiger shark movements in the western and central North Atlantic Ocean in long-term studies based out of Bermuda, the Bahamas, the Cayman Islands and the US Virgin Islands.

The sharks’ movements are being studied by employing three types of electronic tagging technology that provide complementary information – acoustic tags whose signals are detected by strategically positioned, underwater listening devices (receivers), and two types of satellite tags that relay information on where the tiger shark is and/or its depth in the ocean.

This is a continuation of these studies.
Once again, Tigers are being shown to be highly versatile not only in their diet but also with regards to the habitats they frequent, from coastal to very much pelagic. Also, they are by no means resident but can engage in very wide ranging migrations, this possibly associated with opportunities for predation. Interestingly, this does not appear to be a uniform pattern but rather, it appears that different individuals engage in completely different behavior. As an example, check out the Grand Bahama page and you will see that whereas Nikole and Christina prefer to stay close to the coast, Jamin appears to be way more adventurous - this very much like the Bermuda Tigers that are true pelagic wanderers that visit seasonal hot spots.

Please explore the site and the tracks.
I particularly liked the animated tracks as they feature a running time log which does a great job in depicting time spent in an area or distances traveled.

Enjoy!

Caymans' Nassau Groupers - great News!

Great artwork by Guy!

Remember this post?

Now, the Cayman Islands have extended the seasonal protection of the endangered Nassau Grouper spawning aggregation sites for another 8 years. Full story here, Guy's reaction here.

And here's a really nice PSA on Guy Harvey's website.
But: why is embedding not enabled - isn't this about spreading the message?
Anyway: Kudos to everybody involved!

I obviously haven't seen it.
But from what I can discern, it features the iconic Doc aka the Grand Mufti of Shark research, Guy Harvey and Mahmood - and for that reason alone I fully expect it to be nothing short of stellar!
Story here.

And here's the trailer - narrated by none other than Guy himself!

Bravo Mahmood!


Mahmood is Prof. Dr. Mahmood Shivji of the Guy Harvey Research Institute and the Save our Seas Shark Center, both at Nova.

He's the guy who gets all of our DNA samples and you may have heard of him in relation to his recent discovery of a forensic tool (the actual paper is here) to pinpoint the geographical origin of the fins of endangered Scalloped Hammerheads from the Hong Kong Shark fin market.
This is how Reuters covered it.



Now Mahmood has posted this brilliant video about what happens in the lab once they have taken a small sample of the fins. Shame that there's no embedding feature.

Anyway, a big Kudos for the discovery and congrats for having produced a compelling piece about GSI and the need for Shark Conservation.
Bravo!

Fischer Reality Check - Comments by Dr. Michael Domeier!

In-water SPOT-tagging of an enormous GWS - source.

Sorry for the protracted silence.

We've been extremely busy.
Plus, I've found myself embroiled in a rather unexpected and increasingly pointless debate with Chris Fischer of Ocearch.

Chris should have followed the advice of Domeier's publicist, see below.
Now the exchange has piqued the interest of the man himself who has sent me a vigorous rebuttal of Fischer's assertions, initially however with the request not to publicize it as he wanted to keep to the high road and instead let Karma take its course.

Well, I don't believe much in Karma.
It is unpredictable and takes much, much too long to eventuate.
So upon much cajoling by yours truly, here are Michael Domeier's comments - and from what I recall and have been able to observe from the sidelines, I for one have no doubt that they are a truthful representation of the facts - tho still way too karmically polite!
Unabridged - although the formatting is mine.

Enjoy!

Any PR expert will tell you to never get dragged into a public, negative pissing match… excellent advice that I try to follow. 
But once every few years I’m forced to slide down the slippery slope to correct serious misinformation that affects me, or my organization… misinformation that only I am capable of correcting. 

Some people are so comfortable stretching the truth that they actually begin to believe the lie themselves. 
Remind you of anyone/anything?? A popup tag removed from a shark at Guadalupe Island? A tag presumably recovered from another shark off El Choyudo? Pictures of Junior circulated with wounds falsely attributed to my tagging of the same shark a year earlier? For each of these things I finally made a concise statement that set the record(s) straight. Here we go again, but perhaps not as concise due to the complex situation. 

Chris Fischer, at every opportunity, proclaims 1) that he spent $5 million to fund my research; 2) that he enabled me to become a great researcher; 3) that I greedily hoard the data and don’t share with the public; and 4) that he developed the equipment and methods to capture and tag large adult white sharks. 

1) There is no way Chris Fischer ever spent $5 million of his (or anyone else’s) money on my research. 
We joined forces to conduct 2 expeditions before he got a TV deal. My last Guadalupe Island expedition (Fall 2012) cost about $40K… and that was with the boat making a profit. So do the math. Also, there was never going to be a second expedition (2008). Chris had a big sponsorship from Red Lobster and was departing for a ‘round the world expedition. I even flew to Ft. Lauderdale to attend his big send-off party at the IGFA Hall of Fame. I flew on my own dime, wished him well and said goodbye. When Red Lobster dropped him, ending the voyage before it even began, we got together to do another expedition in 2008. He did not put his life on hold, bet his savings, etc., to provide me two boat rides to Guadalupe Island. I was the one who spent months and months in preparation for each trip… he just showed up at the dock. 

Yes, he paid for 2 trips to Guadalupe, but then struck a TV deal that allowed him to recoup those costs as he was getting $400K/episode. 
We were able to make multiple episodes from a single trip. Furthermore, I tapped two other private foundations to help pay for the tags and research; financial support that he never acknowledges. Fischer was fairly paid for all of the work we did together… this was not a huge philanthropic venture. On the contrary, he made it clear: “no cameras no trips.” The huge $$ figure he throws around must be for the entire operating cost of his ship and production company for each year he was making these television shows. But that’s not a fair way to account for the actual cost of the research (a fraction of the yearly operating budgets were due to the handful of research trips)… and he never discusses the INCOME. Any real accountant would tally just the costs of the specific trips… or think like this: what would it cost to charter a vessel for each research trip, and then subtract the income! Perhaps he took a loss, I don’t know; my organization took a financial loss… but no way did either of us wrack up losses in the millions. 

2) None of my recent white shark papers would have been possible without the 10 years I put in the field before I met Fischer. 
Fischer just happened to be in the picture as I began to really put all the pieces together. I knew SPOT tags were the only way to push the science forward. I also knew the sharks would be easy to catch, but I wanted to lift them from the water to safely remove the hook and do extra sampling (sperm, blood etc). I was developing a stand-alone pneumatic lift to accomplish the task. When Fischer showed me a picture of his new boat at a Billfish Foundation Board Meeting, I instantly recognized that the lift designed to pick up a yacht could shortcut my lift building plan. I asked if I could use the boat. The answer was “yes,” but only if I allowed cameras. I had never cooperated with a film maker in all my years at Guadalupe (well… Guy Harvey is an exception… but he’s an exceptional guy), and I had requests on a monthly basis, but this seemed like a good trade. 

When it comes to enabling, I think one needs to look at who really benefited from this collaboration. 
I brought Fischer into my world… he took my idea and crafted an entirely new career/image for himself. He even used the experience to gain his coveted Explorer Club status. Brett’s a good guy, but even he will tell you he (Brett) had no interest in catching sharks… even as we were heading to Guadalupe for the first time. If it wasn’t for my bringing Fischer into the marine science world, and consequently primetime television… he would be sitting in his home in Park City without a big boat waiting at the dock. Yes, he was about to lose the boat. If I had stayed true to my original course I would have accomplished the same work, it just would have taken me longer 

3) I do not hoard data. 
Like any professional researcher, I gather data until there is enough to analyze, allowing me to write an excellent publication. Then I publish and share with the world, just like every other working researcher that I know. In fact, I was careful to publish our latest findings in an open access journal, so the entire world could read the paper for free. 

I also disseminate results on our Facebook page. And yes, I have an app that costs a whopping $3.99… that helps me fund the research (actually… it brought in enough to do a nice upgrade (soon)… but not much more). I don’t have huge tv deals and corporate sponsors. So what’s the problem? Fischer slammed my app (and me personally) when it debuted and encouraged people not to purchase it. No, I don’t give the data to Fischer… why should I… it’s my data? He got all the TV shows and celebrity status he wanted… I got data. Furthermore, releasing research results prior to publishing can be problematic when the time comes to publish. Ask any researcher about that. I’ve been sharing more data lately simply to try to keep my organization afloat. But the last person I want running around the world, interpreting my unpublished data, is Chris Fischer. But that hasn’t stopped him from doing so. His brand building (photo shoots and interviews with big hooks draped around his neck, the hyped fishing template for the show) really hurt my reputation as a legitimate researcher. 

4) For our initial expedition I told Fischer he didn’t need to bring anything, just bait…I would do the rest.
I did the rest… and he forgot the bait (thus the infamous bait arguments on TV program). I conceived of the idea to use his yacht-lift to tag sharks, I designed the cradle, I designed the hook, the buoys, the line… everything. When the cradle didn’t work the way I had hoped, I was the one that tore it all down and fenced in the entire platform… Chris wanted to use the crane to pull the sharks onto the platform (yikes). Yes, my home-made hooks were prone to bending and breaking, but there was no place to buy such big circle hooks and we caught a few sharks that first year. And yes, the crew helped refine my concept for safely catching and handling the sharks. 

The SPOT tags used by all now, were built specifically to my design specs. 
I tried the off-the-shelf version and it failed. My version worked, and continues for me and for those who have followed. Lately I’ve made significant changes to the attachment of those tags… but that’s another story. 

Every single place we went with the ship was under my specific direction. 
I was in the wheelhouse each time we dropped anchor, putting the ship on my numbers… and we caught and tagged sharks every place we went. Our success was not due to the exceptional fishing prowess of Fischer; it was due to years and years of observation, study and note taking.

I  hate this sort of thing, and hopefully it will be years before I have to put myself out there like this again. 
But sometimes it’s a necessary evil. There are moments of clarity when you have to act, today was one such moment. Let me share a similar moment from years ago: while doing a big promotional push before the debut of our first TV episode, Fischer and I were both doing nonstop interviews in NYC. During a short break, my wife and I watched one of Fischer’s interviews, on FOX News, from the lobby of the hotel. We sat in stunned silence as he proclaimed that the entire research program was his idea and that he had pulled together the boat, crew and research. Just weeks prior he had proclaimed that I was nothing more than “a passenger with permits.” Suddenly it was clear this was not a good situation for me. The science message was being lost by the growing ego. In the end, I could not bear to watch the series that was based upon my own hard work. I tried to watch an episode during the season when Peter Klimley took my place… I was sickened at how Peter was made to look so foolish… turned it off again. 

There have been a huge number of people on-and-off the Fischer bandwagon, many of whom can confirm my statements if you care to track them down. Brett was a good friend… he knows the truth… unfortunately our friendship could not endure the awkwardness to keep in touch. 

I will be the first to say that I’ve noted a different tack from the Fischer camp lately… less fishing hype and more attention to the fish being studied. 
Perhaps lessons have been learned. But in my heart I know Fischer’s ride is about recognition… not about sharks. He didn’t know a clasper from a cloaca before I met him. I hope he does great things for the world… I hope he becomes more self-aware and learns to let his actions speak rather than his words. This whole thing started because he could not stand the fact he was not getting all the credit for a paper Nicole and I invested nearly 15 years to produce. 

Dr. Michael Domeier

PS: simply brilliant post by Patric here - kudos!
“I once thought (call it an evolution) that science and tv could be married together to deliver the best and brightest to waiting audiences. Then the major cable players started cutting doco budgets, slashing and burning them in an almost Visigothic manner until a 60 minute show was left with a budget of $150,000 and that included post production.

What do you get for $150,000 or less? You get Gurney Productions and sharks. There will always be someone who is willing to drop their pants and chain wrap a Tiger shark, and film it, (yes ABC that's you buddy) for a few film credits and the chance to film the next piece of shit that comes down the chute.”
PS2: Megalobomb unleashes!
The most challenging experience one will face during a career in white shark research is being suckered into working with someone that is a dick. Like a one-night stand, they/their projects may look attractive and say all the right things, but then you wake up and realize that you’re some wrinkly married man’s mid-life crisis.

A Fiji Bull Shark?

Carcharhinus dakuwaqa? Quite possibly!
Click for detail - and I mean it!


I knew it!
Not only are our bulls huge and the most incredible collection of charismatic, intelligent sharks on the planet, they may well be a totally unique population - if not more than that!
This was revealed last week at the AES meeting.

From the poster.

Global Population Genetic Structure and Parentage Analysis of the
Bull Shark (Car
charhinus leucas)

Project Synopsis

The bull shark (Carcharhinus leucas) is a globally distributed, large coastal shark that occurs in marine, estuarine and freshwater habitats.

It has been assessed as near threatened by the IUCN, is caught in recreational and commercial fisheries throughout its range, and shows evidence of recent declines in the Gulf of Mexico. Regional population studies have reported mitochondrial but not nuclear differentiation between the western North and South Atlantic (Karl et al., 2011) and among juvenile C. leucas sampled in river systems across northern Australia (Tillett et al., 2012).

We expanded on these studies by evaluating the global population genetic structure of C. leucas using 12, bi-parentally inherited, nuclear microsatellite loci and a globally distributed set of 470 samples. Our microsatellite data revealed strong genetic differentiation between samples from the western North Atlantic (WNA) and Indo-Pacific (I-P). No population structuring was detected within WNA and Indian Ocean sampling sites.

Fig. 1. Species global distribution indicated in gold shading. Sampling locations with fewer than 10 samples were not included in the population-based differentiation statistical analyses (Fig. 2) but were included in the individual-based analyses (Figs. 3 & 4).

Notably, however, samples from Fiji demonstrated statistically significant genetic structuring from the remaining locations sampled.

Fig. 2. Charcharhinus leucas genetic differentiation based on population-level statistical analyses. Colored shapes (ovals and square) represent genetically distinct populations. FST values (p = 0.0000) between each population pair are indicated by arrows. Sampling locations (indicated by circles) within each population are not genetically differentiated.

Assignment testing (GeneClass2) showed evidence of a low-level of first generation migrants from the WNA and western Pacific among the southwest Indian Ocean samples, a surprising finding considering the strongly coastal nature of C. leucas. Finally, parentage analysis of 2 litters suggests that the species may be genetically polyandrous, although this hypothesis will need further testing with more litters.

Conclusions:

Individual and population level analyses are concordant in showing at least 3 genetically distinct populations:
  • Western North Atlantic
  • Indo-Australia
  • Fiji
Fig. 3. pie charts indicate the average proportional membership coefficient of individuals in the 3 distinct lineages inferred from nuclear microsatellite genotypes by the program STRUCTURE. Pie chart sizes are roughly proportional to sample sizes.

Three 1st generation migrants were identified, indicating contemporary movement from both the Atlantic and Pacific oceans into the Indian Ocean. Complex patterns of migration and population structure require coordinated regional management efforts.
Parentage analyses of 2 litters revealed multiple paternity in both litters.

So there you have it!
This is the result of many years of DNA sampling on Shark Reef whereby so far, we've been able to send more than 70 samples to Mahmood - and counting as there are other, more local aspects we would like to explore.

So, do we have a Fiji endemic?
Probably not at all, because nearby locations like e.g. Tonga and Samoa are very likely to harbor the same Sharks. But from everything we know, Fiji with its robust population of Bull Sharks may well be considered to be the epicenter of this genetic strain, meaning that it would be perfectly acceptable to call this the Fiji Bull Shark - and depending on whether this is a subspecies/race or even an own species: how does Carcharhinus leucas dakuwaqa or Carcharhinus dakuwaqa sound to you!

Anyway, is this mega cool, or what!

Shark Fin Soup – nothing but a Myth?


From the website of Wild Aid.
Demand for shark fin soup, an expensive delicacy in Chinese culture, has skyrocketed in the last twenty years due to growing Chinese economy.

Not so fast! says this article in the Guy Harvey Magazine.
Apparently, Shark Fin soup hasn’t got anything to do with centennial Chinese culture, nor is it some status symbol originally reserved for the Ming emperors, nor is it particularly expensive nor is the increasing consumption in any way linked to the advent of a wealthy middle class in China.
Instead, the article says, the load of bull surrounding the international regulation, historical legacy, and modern demand for shark fin soup got too big and smelly for me to ignore. It turns out that what you believe about shark fin soup is largely a matter of what lie you’re willing to swallow.

So, why do they eat the tasteless slimy stuff?
Because they can: because it’s there, because it’s actually cheap and because they couldn’t care less about its provenience:

…as Fuchsia Dunlop noted in Shark’s Fin and Sichuan Pepper, “The Chinese don’t generally divide the animal world into the separate realms of pets and edible creatures.” “When I was living in China, animal cruelty was just not an issue,” Dunlop told me. “There was no kind of emotional identification with animals at all.
“For most Chinese, there’s no difference between eating a wild animal or a domesticated one. A shark might as well be a cow, or a hamster. As travel writer Maarten Troost notes: “The Chinese have an expression: ‘We eat everything with four legs except the table, and everything with two legs except the person.’ They mean it, too.”
So, the Chinese are hungry, numerous, unsentimental, subject to the same insidious, aspirational marketing forces as everyone else.


And all those campaigns targeting the Asian consumers?
Frankly, dunno – meaning that I remain unconvinced: the article itself contains statements by the Mary and conflicting statements by a representative of the Pew. And when I interview our numerous Asian customers, most of which are of Chinese origin, the picture remains equally ambiguous and equally bleak: from what I’m being told, whereas consumption may be dropping among the younger urban generation in places like Hong Kong, Singapore and KL, it remains high elsewhere, especially in mainland China – and that would mean that tens, if not hundreds of millions would still need to be reformed before a single Shark would be spared!
And yes, I’m rather stubbornly repeating myself, check out the above link!

Plus, there’s this.
Assuming that the usual volunteer bleeding hearts are going to step up and stop the shark carnage simply isn’t realistic.
There are lots of volunteer bleeding hearts doing that already and their efforts have difficulty competing against commercial concerns that can spend tens of millions of dollars lobbying in order to protect hundreds of millions of dollars in profits.
Probably true!

Solutions?
  • If the trade is supply limited, one must target the supply side: you protect African Elephants and Rhinos in Africa, not by trying to curb the demand for ivory and Rhino horn in Asia – by the same token, you gotta protect Sharks (and e.g. Tuna) where they are being harvested! Conversely, as there really is no real demand for Whale meat in Japan and whaling is thus demand limited: you protect Whales by eliminating the remaining tiny demand in Japan, not by targeting the whalers in Antarctica: let go of the ideology so they can let go of their nationalistic phobia, give them a quota - and then let them try to justify whaling from a purely commercial POW!
  • We got to focus on sustainability, not on prohibition, meaning that we must be willing to compromise! Who are we anyway to tell anybody what to eat as long as that is being done sustainably! Granted, for most species of large Sharks, sustainable harvesting appears unrealistic – but at least in theory, some of the smaller species are adequately plentiful and fecund to warrant a quota.
  • Finning is wasteful and cruel and needs to be stopped.
  • Any strategy will only be successful if on top of legislation, it includes enforcement, mitigation and education. The latter require adequate resources that are generally lacking in third word countries, meaning that we must contribute with more than mere rhetoric. I have no doubt that every single fisheries official is acutely aware of the problems and of the need to fish sustainably, and that given the adequate support (including the eradication of corruption where necessary), he will be eager to implement forward looking policies. So, let’s not only lecture and petition, let’s be part of the solution and the implementation as well!
  • In order to be credible, we gotta be rational, goal oriented and smart – and fact based, see above!
It always boils down to the same rules, doesn’t it.
Let’s go do it!

PS bravo Patric for having written this. As to whether the Asian mafia controls the Shark fin trade: as the trade has greatly expanded and gone mainstream, they probably do not control it anymore - but they sure use it for money laundering!

So Far so Good!

Guys, this ain't a circle hook - well spotted by Lawrence!

Some you win, some you loose!

Case in point: this recent post.
It contains a very oblique reference to the Guy Harvey Ultimate Shark Challenge - and now both sides are equally pissed off! The proponents believe that I'm criticizing it unfairly, the opponents criticize me for not having spoken out against it!
Guess it serves me right for not having been my usual abrasive self!

Thing is, I'm very much on the fence on this one.
In theory, I support it for being the better alternative to kill tournaments, at least in the short term; from the heart, I do not like it as I'm against trophy fishing for Sharks; and in this specific case, I still need to be convinced that this is genuine and not just some kind of business spin.
As always, time will tell!

But as the title implies, I'm rather impressed - so far!
You may first want to read the general outline here and then, the recap of the qualifying round here.

From what I can discern, this has been off to a great start!
This looks like a meticulously planned and flawlessly executed event and I must say: kudos to all those who came up with the initiative and invested what must have been a gargantuan amount of sweat equity into making this happen!
Technically speaking all I can say is job very well done!

And there's more good news.
Firstly, the apparent sidelining of real man Jack Donlon - and if so I say, good riddance!
Secondly, the re-appearance of Bucky Dennis among the catch-and-release anglers! If this indicates a genuine change of heart, it would be a truly spectacular confirmation of the effectiveness of the tournament's new format!

And ethically, as a conservationist?
Still not convinced!
This has now morphed into an event where fishermen catch and tag specimen for the research of Mote, something the Shark researchers do anyway.
That in itself is a good thing as it furthers our insights into the animals' life history and since the need to release them in good health has mandated the deployment of circle hooks and tail snares, along with very heavy tackle in order to get them to the boats in a minimum of time - not very game as in game fishing but probably the least invasive way to go.

Still, this is the principal mating and birthing season and this means that this is once again directly targeting pregnant females, some of which will certainly perish despite of all the precautions - especially some of the highly endangered Great Hammerheads who are particularly prone to dying of exhaustion as they are known to fight til the end.
Could next year's dates be moved to a less sensitive time frame?

Long story short - I'm still undecided but at the same time, looking forward to more news about the tournament proper!

The immediate question now being: who did I piss off this time!

PS: this is very cool - thanks Underwater Thrills for posting it!

Hit and run in the Atlantic!


Very interesting!

Once again, some stellar stuff by Guy Harvey & Co.!
I literally stumbled across this plethora of information about Atlantic Ocean Tiger Sharks when googling for the pic of Doc in the previous post. It very much confirms the results from Hawaii insofar that Tigers roam immense ranges spanning thousands of miles. Are they proper territories? Probably not as that would imply that they are defended against conspecifics which does not seem to be the case as most tracks overlap.

The picture that is emerging is that Tigers are basically hit & run predators.
When they are not exploiting regular periodic food aggregations like the Laysan Albatross fledglings in Midway or the Turtle mating sites all across the South Pacific and probably elsewhere, they are always on the move, make a point of turning up at irregular intervals, linger for a while and then carry on. Like this research in Australia's Shark Bay shows (watch the video: cool!), they thus influence the behavior of their prey that never quite knows when they will appear and have to engage in costly avoidance behavior. Check out the research papers (bottom of page) or consult the very good synopsis in Predators as Prey by Oceana, one of the bibles of every Shark lover.
Fascinating stuff!

But what was Correia doing in July, smack in the middle of the Atlantic Ocean (click to view)???
It really is true that the more we learn, the less we know!

Which obviously brings me back to Fiji!
2010 has been an exceptional year for Tigers as so far, they have been around throughout the wet season from January to May and continue to be regular visitors at present.
This is obviously speculative, but we correlate this with this year's El Niño that led to a very dry Summer, meaning that there were no floods when the Tigers are believed to linger closer to the rivers. We're now in a La Niña, meaning that the weather will remain dry but cold until September and then likely become very wet indeed, with heightened risk of flash floods.

In brief: Tigers now, but they may well disappear towards the end of the year!
And again: this is pure speculation as we just do not dispose of enough yearly data sets to correlate our Shark sightings with ENSO!
Meaning that all I've said so far may be totally wrong!

Scarface by the way, being the usual hussy (being aplacental viviparous, she doesn't even have to wait like the other Carcharhinids), has once again gotten herself into trouble and is again very much pregnant and consequently huge - and I mean HUGE!
The way she looks, she'll be leaving us soon to engage in her usual months-long trek to her unknown pupping grounds, something we may well once try to decipher going forward.
Same-same for the big Bull ladies, some of which are are definitely rubicund and accordingly famished!

All-in-all, August diving is just great!
Stellar viz, nice cool weather, plenty of Sharks!
So, what are you waiting for...
