The Impact of GWS Cage Diving - Paper!


Bingo, and I cite,
"Best practice" among cage diving operations apparently consists in just teasing, but never actually handing any bait to the Sharks.
Were I a Shark hugger, I would immediately object that letting the Sharks waste precious energy on fruitless "hunts" is to be rejected as it is likely harmful to the animals.
Yup that would be yours truly a whopping ten years ago!
And now Charlie has concluded his investigation and comes to the following conclusion (emphasis is mine)
Although sharks are enticed to the cage-diving vessels with baits, industry regulations do not allow operators to feed white sharks and strict limits on the amount of bait and berley are now in place in South Australia and at other white shark cage-diving locations (Bruce, 2015).
Energy burden from the increased activity is, therefore, not rewarded by regular bait provisioning.

Some baits can, however, be consumed when sharks approach the baits using high speed or stealth (Huveneers et al., 2015).
The baits used in SA are composed of gills and stomach lining of southern bluefin tuna and are not as energy-rich as white shark’s natural prey while at these sites (e.g. pinnipeds). Whether the infrequent consumption of these baits provide sufficient energy to compensate for the increased energy expenditure associated with sharks interacting with the operators would depend on the calorific value of these baits and the frequency of white sharks successfully feeding on the baits, both of which are currently unknown (Brunnschweiler et al., 2017).
Spending time interacting with cage-diving operators might also distract sharks from normal behaviours such as foraging on natural, energy-rich prey like pinnipeds.
Combined, these suggest that the increased energy expenditure associated with cage-diving interactions might not be compensated for by either bait or natural prey consumption.

One could, therefore, argue that white sharks should be able to feed on some bait to compensate for the energetic losses resulting from interacting with cage-diving operators.
Bioenergetic models (e.g. Barnett et al., 2016) would, however, be necessary to accurately assess the likely effect of cage-diving on white shark energy balance and whether such compensation is necessary or beneficial. Beyond the potential for short-term energy intake, other aspects of food provisioning (e.g. quality of food, potential for changes in foraging behaviour) would also need to be considered.
Good one - and obviously, totally not surprised!
This is now the second paper (re-read this!) stating that NOT feeding is probably not a good idea - and whereas I concur that further investigation into the precise energy balance, etc may be beneficial, we should really not caught up in minutiae and finally do the right thing.

So what's it gonna be?  
Now that the evidence is in, will the regulators in Australia and elsewhere do the right thing and allow for proper feeding of those Sharks - or are they going to continue cow-towing to those in the populace who will contend that it would lead to more Shark attacks, and the like?
Remember that when it comes to feeding and conditioning Sharks, 99.999% is being perpetrated by the fishermen and not us - so assuming that it really is a big problem (spoiler = it aint: these are the real problems, with overfishing being the principal threat to Shark populations) let's maybe first look there! !
Anybody taking bets?

Anyway, enjoy Charlie's paper!
To be continued no doubt!

Guadalupe - more Shenanigans?

Indeed, a picture is worth a thousand words - click for detail! Source.

Watch.



Sigh.
Forget all that idiotic clap trap -  and no, no amount of soul searching and overcoming of personal phobias, or whatever, can detract from the simple fact that this is reckless and 100% illegal pure and simple.

And this shit?
That would be this dude, clearly a repeat offender along with his illustrious shark team, all of which are already planning their next trip for this fall, undoubtedly for the Sharks.
And the research permit for this? Questions questions!

And how about this last glorious feat.



Yes, that cretin is really brandishing a piece of Shark bait!
I mean - seriously!

Just great aint it.
And yet and despite of all the unequivocal evidence, CONANP appears once again either incapable and/or unwilling and/or too cowardly and/or, gasp, too corrupt to enforce its own rules and keep those people, and their serial enabler off the island!

SOFA - quod erat demonstrandum!

The SOFA: a humongous area in the NE Pacific where GWS disperse to forage.

Behold - and yes it is long!



Synopsis here - and yes this is impressive as hell.
And here's a nice, and short video about the technology - again, very impressive in terms of scope but also cost!



And now, re-read this.
See what I mean?
  • The GWS are by no means "aggregating" but instead, they are actually dispersing in a huge area after having aggregated at the coast! I mean, seriously: watch the first video at 42.12: does that look like congregating to you?

  • In the SOFA (which is the much better name than Café) they very much appear to be foraging and not mating: case in point, just listen to what Barb's got to say at 1:21ff of the first video where she explains how the data illustrate that those Sharks engaging in ROD are most likely targeting prey like Bigeye Tuna.

  • Which obviously means that the GWS are mating in the known coastal aggregation spots like Domeier had postulated all along!

  • And those infamous, and totally cockamamie hypotheses by Jorgensen and Chapple, respectively, that they may be lekking or, gasp, sniffing for female pheromones?
    Right...

  • And oh yes that would very much be a q.e.d - just saying!
    And no this time I'm gonna be magnanimous and refrain from mentioning sniffing glue and the like! :)
But I'm digressing as usual.
Keep watching this website and also, keep watching this space.

To be continued no doubt!

Thanks for all the Fish!



I must say, this is really nice.
Firstly, because it doesn't do the usual touchy-feely treehugging thing but is instead very personal albeit a tad overly dramatic - the more as Juliette has been diving with us before and was by no means frozen in fear but did instead thoroughly enjoy the experience; and secondly, because this is the very first article about us that mentions the all-important toilet etiquette - and yes please do not pee in our rental wetsuits!

So, a big vinaka vakalevu from all of us.

Bull Shark Smiles!


This is just awesome - click for detail!

What can I say but, Vinaka Christian!
 

No more Shark Sanctuary in the Marshall Islands?


I was wrong.
The Marshalls are not among the "best" - read the above (= click for detail).

Yes this is not good.
In brief, the Shark protection in the Marshall Islands is quietly being rolled back, and nobody appears to give a rat's ass.
Once again, it's all about the money: the huge earnings, the jobs and the according political clout of the fishing industry versus the money needed for enforcement but also the establishment of  alternative livelihoods.
In fact I remember distinctly how back then, Pew strongly suggested that following the designation as a sanctuary, the Marshalls would become a world-renown mecca for shark tourism like Palau - which has very much unsurprisingly not happened as the logistics for running a dive operation there are just simply totally prohibitive.
And like I said back then, legislation can be reversed - and now it has.

And Pew - anybody anybody?
Yeah, right.

Not a Shark Cage?


Right - click for detail!

Read this.
Those are Western Australia's Rules for Shark interactions by Aquatic Eco Tours. “Aquatic eco-tourism” is defined as tourism relating to fish in their natural environment and includes the viewing or feeding of fish but does include the taking of fish.
And these are the rules pertaining to fishing. 

And now watch, and read about this fucking fiasco
Yup that would be yet another production for Shark Week barging in and rubbishing yet another location. And surprise surprise: like he has e.g. already done in Fiji, the Bahamas, Guadalupe and New Zealand, the hypocritical  king of Shark porn is once again smack in the middle of it all.

Just great isn't it.
And let's be crystal clear about it: this is not fucking CinemaScience (I mean, seriously!!!) or environmental filmmaking let alone conservation = this is illegal, unethical and exploitative rubbish perpetrated by human garbage - and let there be no doubt that Discovery Channel is certainly an accomplice, too!
Anyway, not surprised - but it sure is a crying shame seeing Charlie's name associated with that shit!

And like an old broken record let me repeat
Here are my own questions to fellow Shark diving operators, researchers and conservationists.
  • Are we going to continue pretending this aint happening?
  • Are we going to continue watching that shit?
  • Are we the operators going to continue enabling it?
  • Are we going to continue giving our business to operators who do?
  • Are we going to continue associating with those people?
Questions questions - you know who you are!

Now we're at it.
We're finally analyzing our impact on the Whitetip Reefies - and with the original authors having graciously flown in to supervise but also document our experiments, I'm highly confident that we will shortly dispose of solid evidence, the more as the gizmos we are deploying are truly amazing - and totally non-invasive, too!
And like I said back then, I'm equally highly confident that our Sharks are not being harmed.

But we will see won't we.
And should the results indicate that we need to implement changes, we certainly will - and that's a promise.

Philippe!


It's a wrap.

We've just hosted a small shoot.
It's for an educational travel series called Awesome Planet that focuses on earth science topics, is geared towards the 13-19 year old audience, and is hosted by Philippe Cousteau. The show is in production for the 5th season  and averages around 700,000 viewers a week nationwide (with an additional 20,000 / month on Amazon Prime).

And now that I've met him, I must say that I really like the dude.
Highly knowledgeable and undoubtedly passionate, world renown and yet refreshingly humble and funny, he is the real deal, and it has been a true delight and also an honor working with him.

This is exactly what we like to facilitate.
Like the episodes of Einstein, this is something respectful and educational that doesn't want to exploit the Sharks and focuses on what we actually do as opposed to some contrived story line featuring the usual assortment of self-enamored media whores.

Which brings me straight to that shit with Ronda Rousey.
No it was certainly not us - along with many other reputable people ranging from potential hosts to researchers to shooters we decided to turn it down as we ultimately want nothing to do with all that gratuitous hype and mental midgetry that are this show in particular and Shark Week in general. 
But of course there will always be some desperate operator enabling that horrible exploitative crap; and of course one can always count on the usual pathetic assortment of self-promoting hypocrites like the king of Shark porn and the Tweedledum and Tweedledee of pseudo-conservation who will always be all-too-happy to come clowning around in front of the camera and molest some poor unsuspecting Shark. 
Case in point - yes that would be conservation messaging, or whatever, and I can certainly leave it at that!

But I'm digressing as usual.
What I really wanted to say is, merci beaucoup, ça a été un vrai plaisir - and a big shout out to Jason of Silver Shark Media for having organized and managed the shoot impeccably!

À la prochaine!

Florida Land-Based Shark Fishing - Progress!

From a presentation to the FWC - those Hammers are obviously moribund, or they could not be handled that way. Click for detail.

Behold!

Finally at their last meeting, the FWC has taken note.
So far, the staff have continued to derelict their duties and failed to adequately protect their vulnerable prohibited Sharks by cozying up to the shore-based fishermen, by never enforcing their very own rules and by never following up on the numerous complaints (and evidence!) of illegal activities, and have instead continued to belittle the concerns of the public; but in view of the overwhelming evidence presented, the commissioners have now decided that it was high time to draw up unequivocal regulations to stop the shenanigans. 
Yes they will take some time to draft and implement - but here's to the staff taking note that the status quo has become unacceptable and starting to finally fucking do their bloody job; and to the shore-based anglers to fucking clean up their act in order to avoid a total ban of their activity!

Kudos to everybody involved.
But whereas some of the usual shameless self-promoters are already taking public victory laps (shame on you Angela - you know who you are!), the real heroes prefer to keep anonymous - especially one incredibly impressive gal who has been busting her ass setting up a citizen initiative and coordinating much of the concerted effort.
She writes,
You know why this campaign has been different and successful?
Because I FIGURED IT OUT.

I didn’t just start screaming at FWC.
We respectfully communicated and I learned lots along the way.
I figured out how they were trying to handle the issue “education rather that regulation” and then spent 9 months on a daily basis illustrating to them why their approach wouldn’t work. I do know many people have submitted crap to the FWC over the years, that doesn’t do anything. We recognized this issue and immediately spent time and money to address the Commissioners at their meeting of July of 2017 =
within one month of starting our group, and at that time we asked the FWC Commissioners to put land based shark fishing on a future agenda.

Here is where the hard work starts though.
We still have so much work to do.
Yes indeed you do.
There are several topics requiring detailed attention i.e. a) blood baiting and public beach safety, b) gear restrictions, c) handling of prohibited species, d) prohibition of shark fishing from man made structures and finally, e) potential licensing and permitting, and there are already efforts underway to properly address each of them.

Want to help make a difference?
Should you live in Florida, have the required knowledge and skills and want to lend a helping hand, you will have plenty of opportunities - and with most good people wanting to remain anonymous: if you don't know whom to contact, best address yourself to the ASC who will undoubtedly point you in the right direction.

Wishing you the best of luck.
And remember: less talking more doing!

Oh and more good news: there will be no harvest of Goliath Groupers!

Florida Land-Based Shark Fishing - FWC Meeting!


Remember those last posts?

But now there is an, albeit tiny, chance for improvement as the FWC is slated to discuss the matter at its next meeting in Ft. Lauderdale on April 25 and 26.

So you Shark loving folks, here's your chance.
First, inform yourselves because just attending to make the usual breathy noise will most certainly not cut it; and then go there and have your voices heard!
FWC summary memo here, presentation here.

And since we're at it.
There will be a discussion about opening the protected and generally Critically Endangered Goliath Groupers to limited harvest.
This is obviously highly controversial and you should inform yourselves and participate in the discussion. FYI, personally and despite being an avid angler I would vote against it as from a recreational fishing perspective, catch & release is legal and perfectly sufficient - but that's just me. And if there really are too many in Florida, how about catching some and releasing them where there are not enough which is everywhere else!
FWC summary memo here, presentation here.

There you have it.
Long story short, stop talking and start doing - and no, the usual tired raising awareness counts for less than nothing!

Wishing you the best of success!

Shark feeding in Bora Bora - Paper!


Oh well.

Eric keeps cranking therm out, and I am irritated.
This time it's about those Lemon Shark feeds in Bora Bora, and several Shark bites that ensued, which is incidentally much like what happened with those Lemons in Moorea. 
The description of the events is probably correct and like I said back here, much if not all is a direct consequence of those being multi-user sites with poor and/or not commonly observed feeding protocols, and with competitive pressure and bravado leading to unsustainable practices.
Once again it's same old same old and as such, really quite boring - the more as barring a miracle, those French Polynesian dives are very likely a thing of the past anyway!

But I remain irritated.
This is because Table 1 appears to want to expand those species-, location- and context-specific observations to Shark diving in general, and appears to suggest that especially hand feeding will inevitably lead to bites as per the annoying depiction at the top - click for detail.

No don't worry I'm not going to unleash.
In their generalization, those assertions are simply not correct - and I will gladly leave it at that as we Shark divers know better, and as the naysayers cannot been swayed anyway.

Just this.
Despite of all the breathy punditry, ranging from frankly idiotic to simply frustrating, Shark diving remains orders of magnitude safer than SCUBA - and from a human safety perspective, that is really all one has to know. Choose a responsible operator with good safety protocols both in the water and especially also when it comes to managing potential accidents (= first aid gear and training? Evacuation procedure? Ask!!!), and you should be just fine.
And when it comes to the other real and perceived potential effects of Shark diving, you may want to re-read e.g. this or any other post I've written on the topic.

And anyway.
Let's go Shark diving!

One of the Greatest Experiences You Could have!


Great stuff.

Looks like those dives have left an indelible memory, and we are proud, and also thankful for this small endorsement. And before you get all riled up etc etc: the movie is a fictional story about an extinct Shark and has as much bearing on conservation as, say, Jurassic Park - and no we certainly don't want to discuss it!

Thank you Jason!
 

Keni - incoming!



Wish us luck.

Tiger Sharks in Hawaii - Paper!

Click for detail!

And I cite.
Although tiger sharks clearly utilize open-ocean habitats in both Atlantic and Pacific oceans, the majority (78.7%) of satellite location estimates for tiger sharks captured around Maui and Oahu during the present study were in coastal waters over insular shelf habitat.

Tiger shark affinity for coastal waters and shelf habitats has been documented in previous studies in Hawaii, Australia, the Galapagos, the Bahamas and Florida, although movements are generally much wider-ranging over the extensive continental shelf areas off Australia and Florida, than over the smaller insular shelf habitats surrounding the oceanic islands of Hawaii or the Galapagos.

Conversely, most tiger sharks tagged at Challenger Bank (Bermuda, Atlantic Ocean) predominantly used open-ocean habitat.

These apparently conflicting patterns of open-ocean versus coastal habitat use by tiger sharks may partly stem from the demographic characteristics of sharks tagged in these different studies.
For example, eighteen (95%) of 19 highly-migratory tiger sharks tagged at Challenger Bank were mature males, whereas tiger sharks tagged during the current and previous Hawaii studies were mainly (59–80%) mature females which predominantly utilized coastal habitats, and tiger sharks exhibiting high coastal residency in the Galapagos were predominantly (85%) sub-adult females and males.


These differences in habitat use are consistent with habitat segregation among different life history stages, with sub-adults of both sexes and mature females occupying coastal areas, and mature males occupying offshore habitats, but likely also reflect the species ability to adapt the scale and pattern of movements to local resource distribution.
Very interesting!
Once again, Hawaii's Shark Research Team has produced a stellar paper focusing on the residency pattern of Tiger Sharks between Kauai and Maui.

Dunno about you - but I just love love love this stuff.
Step by step, all that initially rather baffling local, regional and global  sneaking around is being deciphered, and I'm just totally fascinated by the insights.

Enjoy the new paper - required reading!

Social Interactions of Sicklefin Lemon Sharks - Paper!

Click for detail!

Very nice!

Check this out.
It describes the behavior of Sicklefin Lemons at two provisioning sites in French Polynesia.
And assuming I understand the paper correctly, the observations coincide to a large degree with what we observe here with our Bulls, i.e. that these largely solitary animals develop a rudimentary etiquette when they aggregate at a provisioning site (and possibly equally at some communal feeding event like a Whale carcass) whereby a) dominance is not necessarily determined only by size and sex but rather, also by individual boldness; b) when there are many Sharks, some particularly dominant individuals react to the  increased competition by monopolizing the food source i.e. the bait cage and in our case, the suspended bin; c) as time goes by, "regular" Sharks appear to become more tolerant vis-a-vis other "regular" individuals of the same species whom they appear to recognize and d) the Sharks appear to tolerate conspecifics with equal ranking but tend to avoid more dominant individuals.
French synopsis here!

I really like it,  and the way they did collect the evidence.
We actually had a masters student do something similar a few years back with the Reefies - but it would be really cool if we were able to replicate this with our Bull Sharks that are our real focal species! The problem is the suspended vertical video camera as per the image at the top, as the rig would be unsightly for the tourists and above all, it would likely be eaten in no time - but I'm sure that we'll figure something out!

With that in mind, keep watching this space!

Recovery of Sharks within a well enforced MPA - Paper!


Very nice - watch!



Paper here, synopsis here.
I must say that contrary to other papers looking at different aspects of those reefs off Western Australia where I am weary of some of the conclusions, I am quite impressed by this one as the evidence for the rapid recovery of those Sharks appears to be rock solid as e.g. evidenced by the video below.



This is good news indeed.
Provided that there is strict enforcement, MPAs appear to be an effective tool in the protection of at least those comparatively less migratory coastal Sharks - and if so, there is certainly reason for hope.

Of course for us this is nothing new.
But good to see our data (and here!) confirmed by research from other parts of the word.

Enjoy the paper!

Gallivanting Tiger Sharks - new Paper!


Remember this post?
Sure you do! :)

Now, check this out.
Once again, this is evidence for the massive influence of environmental factors whereby both the coastal abundance and swimming performance of those migrating Tiger Sharks are being shown to be highest at ~22°C. Consequently, they track their optimal temperature and are thus more likely to be found in coastal areas in winter in the tropics; but towards temperate latitudes, they are more likely to be found in coastal areas in summer, see the figure at the top - and as climate change continues to heat up the oceans, those tracks are likely to shift poleward with according potential consequences for coastal communities, see the example of Sydney.

Very interesting!
Incidentally, this is very similar to what we are currently experiencing with our Bulls who have been shown to favor a temperature of ~26°C.
As the water temperature at Shark Reef has recently hovered around 29°C for a protracted period of time,  the number of especially the larger Bull Sharks has been appreciably lower - and whereas we don't dispose of any strong evidence, it is only fair to speculate that they may have retreated to greater depths or even absconded to places like Kadavu where the water temperature has been significantly lowered by Gita.

But I'm digressing as usual.
Great paper featuring numerous people I like and respect.
Enjoy!
 

Bull Shark Tagging in Fiji!

Very nice!

Check this out.
Pascal was here to assist Kerstin in catching and tagging neonate Bulls. And whilst she has been concentrating on the Rewa River where she has managed to bag more than 100 pups, he and Gauthier of Projects Abroad did fish in the Sigatoka - not as productive as the Rewa but in exchange the results have been  very interesting indeed!
And whereas I'm not at liberty to elaborate quite yet, I can reveal that they will most certainly become an integral part of an upcoming paper, so keep watching this space!

Anyway, lovely post!
And I had to chuckle at the typically Swiss polite reference to cultural challenges = the usual shenanigans where the locals will always try and test any newbie!

Escape to Shark Reef!


Very nice!

Check this out.
Juerg has been the scientific supervisor of our research and conservation for 15 years, and we simply could not be happier with the friendship, the level of cooperation and the many stellar papers our symbiotic relationship has spawned.
Contrary to what some self-appointed literal saviors of Fijian Sharks may want you believe, this is by far the most comprehensive and important collection of Shark research papers in Fiji. As such, it already has and continues to inform Government about sustainable Shark management, Shark conservation and sustainable Shark ecotourism.

And of course this is not the end by far!
As I consult my notes, there are several papers in the pipeline, some of which in preliminary stages all the way to some that are in final review and will be published very shortly indeed.

Keep watching this space!

GHH in Beqa Lagoon!

This is a biggie from Ovalau - source!

Behold!



Yes they are definitely here!
This one is from Project Abroad's BRUV research - and for the moment, the specific location will need to remain a secret lest some eager Shark killer be tempted to go catch himself a set of valuable fins. But it is excellent GHH habitat and we will certainly start looking a bit more closely as this is not the first time a GHH has been sighted there.

To be continued - keep watching this space!

Bull Shark vs Hippos!

Source - apparently this is not too rare!

Feisty feisty!
Enjoy - story here!

A Global Perspective on the Trophic Geography of Sharks - Paper!

Click for detail!

Awesome!

Read this
Yes that's a whole lot of authors, among which some people I like a lot = for once cooperation has been absolutely stellar and one has to congratulate Chris for having been able to pull this off, and for having laid the foundations for a global collective of researchers investigating Sharks by means of stable isotope analysis.

Press release here, report here.
And no, all is so clear and exhaustive that I really got nothing to add!

Kudos - very impressive indeed!
