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!

Science Week!

What an amazing group of researchers, conservationists and industry professionals! 
From L2R, back row: Peni, Gauthier, Wase, Richard, Ian, Charlie and Re; front row Chris, Christian, Manoa and Adam - click for detail!


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.

To be continued - keep watching this space!

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!

PS - Hannah Medd here: yes it has been a dedicated FEW, see her reply to Austin's comment!

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!

It confirms previous findings, e.g. here and here that those Reef Sharks are not (!) apex predators but rather, upper-level mesopredators and that as a consequence, it is highly unlikely that their removal would precipitate any trophic cascades.

Just as a reminder mind you.

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!

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.

Investigatory Bite?


And I cite,
It [the shark] opened its massive mouth and as it's closed its mouth it kind of ripped down as it went to swim away," she said. "There was one metre [missing] off Callum's body. 
I was horrified, then I realised it was just the fin. We're just lucky that it was an investigatory bite and didn't involve any missing limbs. Once we got back on the boat I was pretty upset and a little bit shocked, but it's a really beautiful encounter with out of our most revered apex predator" 
Right.
What a load of horse manure - beautiful encounter my ass!

No that was not an investigatory nibble.
That was a predatory attack, and like they often do, that GWS was trying to immobilize its prey and went for the propulsion; and the dude is really incredibly lucky that he merely lost a fin and not his leg. Seriously, can we please  stop the bloody whitewashing and finally let Sharks be Sharks.

Thank you.

Inverted Trophic Pyramids - Paper!


Read this.

Very interesting!
And with all that evidence, it appears pretty conclusive that those counter-intuitive inverted pyramids do indeed exist.

And the examples at top?
Still not at all convinced, see this post - and I cite from the paper,
However, instances in which energy is exogenously sourced to create top-heaviness (e.g. from another time or another ecological space) present more opportunity for healthy debate.
If, for instance, we allow ourselves to view the operation of communities at non-traditionally ambitious spatial and temporal scales, many of these systems become less top-heavy – or not top-heavy at all. Top-heavy coral reef communities in which mobile consumers draw energy from neighbouring pelagic communities, for example, begin to look more Eltonian when the dynamics of multiple communities are viewed collectively. 

The underlying challenge is that by habit or necessity, the modus operandi of many ecologists is to survey the biomass contained within a community in a snapshot fashion – and such practices poorly acknowledge the spatially and temporally remote processes that shape community structure.
Bingo.
Yes fished remote islands and atolls have less Sharks and big predators (because they have been fished away) and feature conventional trophic pyramids - but unless convinced of the contrary, I must insist that those pristine, unfished ones still don't feature those inverted trophic pyramids (read it!) - at least not permanently!

Anyway.
Enjoy the paper!

Ministry of Fisheries - awesome!

White Teatfish - remember? Source.

Love it!

Fiji's Ministry of Fisheries is showing some teeth - finally!
First they did effectively shut down the illegal trade in bêche-de-mer that has been driving the widespread poaching, and maiming and killing numerous young Fijians. And now they have banned the harvesting and trade in live rock and live coral that has equally been a scourge to our marine biodiversity. Hopefully the latter ban will be relaxed once the coral farmers can come up with a verified sustainable product - but for now the blanket ban is certainly the best solution.
