Fish Warden Course!


Behold!

This is the fish warden class of 2015!
This is the fourth fish warden course we sponsor, and the lineup obviously comprises many BAD boyz and Galoa villagers that will patrol the SRMR - but there is also Ron from Projects Abroad, plus several participants from Vunibau and even the USP that will henceforth patrol and protect the precious Bull, Lemon and Scalloped Hammerhead nurseries in the mouths of the Navua and the Rewa, respectively!
Our thanks go to the Department of Fisheries, The Ministry of Environment, the Police, the Ministry of iTaukei Affairs and the office of the Roko Tui Serua for all having kindly assisted in this endeavor!
And to Nani for having organized it all! :)

Just like I said.
Like always the proof is the doing, not in those breathy announcements and idle talk!

WildAid - Manta Ray PSA!

Source - read it!

And I cite from this horrific report.
It turns out that the shark fin traders, in a move to offset diminishing profits due to the scarcity of large shark fins because of over-exploitation, had revived a relatively obscure, pseudo-medicinal coastal remedy called Peng Yu Sai.
Peng Yu Sai is a soup consisting of boiled Manta gills, Seahorses an Pipefish that is prescribed to treat fevers, chickenpox, and heat in the body. I call this "endangered species soup". The traders then began marketing the remedy as Traditional Chinese Medicine (TCM) and a niche industry was born. It is worth noting that our interviews with TCM practitioners revealed that Peng Yu Sai was in fact not considered a part of TCM.
Much more info here and here.
And now, watch.



Well done WildAid!
But - no Shark Savers logo?

Tiger Beach - cool Research!


Nice!

I must say, I really like this.
It's about bloody time somebody took a long hard look at Tiger Beach - both to assess its biological importance and hopefully, one day, to finally evaluate the impact of those diverging diving protocols!
And since we're at it - could somebody please turn it into a full no-take MPA?

Anyway, bravo Neil for starting to tackle those obvious questions!

SRMR - first Management Meeting!

Epic boatload: Elisabeth; SRMR managers Ian, Bati and El Ciro; El Diego and Kira from Projects Abroad; and a whole gaggle of BAD boyz - click for detail!

Great day!

But first things first.
That lady in the bottom right hand corner is none other than Elisabeth Holland, a veritable Nobel Prize laureate! On our boat!
Who would have thought that possible when we embarked on this crazy journey eleven years ago! Needless to say that she is (obviously!) smart and incredibly passionate - but she's also refreshingly humble, very witty and just a genuinely nice person on top of that.
Really nice meeting her - and yes, we are incredibly honored!

And then we had our first management meeting.
Juerg is abroad but will be here next month - but with the freshly coined Director of Fisheries, Aisake "Bati" Batibasaga, El Ciro and Ian we did have a quorum and were able to formulate a first set of immediate initiatives, first of which will be a substantial increase both in the number of fish wardens and the number of patrols. 
We've just received our first baseline report (= detailed Coral cover assessment, and rough assessment of Fish and Invertebrate abundance) from Helen, and there are indications of recent small-scale fishing. In itself, this is not terribly worrisome - but it IS poaching and we need to nip it in the bud.

And after that, there will be other stuff.
No as usual I'm not telling as it's way too early to divulge any details, let alone make breathy announcements - but i can assure you that you will like it! :)

So, keep watching this space!

Mega Bull Sharks!

Are GWS Populations in Decline?

Source.
 
No, "they" are absolutely not!

DNS doesn't post my comment, so there.
This is just simply wrong. It appears to principally base its assertions on the 10-year old assessment by the IUCN - but in the last ten years, things have obviously changed. 
GWS are one of the best protected species both internationally (CITES and CMS) and nationally, and those decades-old conservation measures are not useless and ineffective but instead, we have plenty of indications that they are quite obviously working.

Here's the situation as I understand it.
  • USA: populations are rebounding on both coasts following the protection of both the Sharks and their pinniped prey. Although there are only published data for California, the increased sightings on the East Coast lead to the conclusion that as a minimum, juvenile and subadult GWS now have a better chance of surviving = there will be more Sharks of a size where they will switch from a fully piscivorous to a mixed diet and become a threat to aquatic recreationists.
    This means that GWS sightings but also strikes will increase and that the authorities need to think now about preemptive measures = education of the public but also Shark-friendly mitigation measures from seasonal beach closures to spotters to exclusion nets, etc.
  • South Africa, reputedly the largest population, appears to be flat to in slight increase.
  • Mexico's population may be at risk due to incidental catches of YOY and juveniles - but nobody quite knows. In any case, the sightings in Guadalupe (= only adults) are not declining which is a reason for cautious optimism.
  • Mediterranean completely unknown - but in view of the desolate condition of all Shark populations there, prospects for the Mediterranean GWS are likely equally grim.
  • NW Pacific population (= Asia) unknown.
Correct?

DNS, not impressed!

Stuff (= much hard work!) has since happened, and they are off to a great start - and this being a mere teaser, you can look forward to a great production that includes everything I love about Pelagic Life!
And btw that's a rarely seen Smooth Hammerhead!

Like I said back then,
These are not some naive tree hugging idealists, these are smart and extremely well connected young professionals who understand the rules and are making realistic, modest plans and  growth projections. And who instead of trying to re-invent the wheel and learn the lessons the hard way, are eager to communicate and learn from other already established ecotourism operators, to then adapt any insights to those local circumstances.
So far, fully confirmed.

Stewart Island - Gloves are off!


From the Stewart Island News, January 2015.
The shark cage debate caught the attention of some MPs who came down here on a fact-finding
mission and held two meetings at the Hall.


Clayton Mitchell and Fletcher Tabuteau hope to take the case to Parliament and convince the
government to change DoC’s decision.

MPs Clayton Mitchell and Fletcher Tabuteau of NZ First recently visited the island on a fact-finding mission to chat with locals and learn more about the shark cage diving issue here. They held two meetings and discussed their assessment of the situation, fielded comments and questions from attendees, and promised to take the case to Parliament. “This is a unique situation and there should be a moratorium while a study is conducted,” said Mitchell.

One interesting angle Mitchell sees in this issue is the new PCBU (Person Conducting Business or Undertaking) work safety legislation coming out, adopted from Australia, which will have a huge impact on the nation, holding every person accountable for their actions at work. The goal is to reduce work-place accidents by 25 percent by 2020. Mitchell wants to point out to the government that trying to enact this legislation in an environment where shark divers and paua divers share the same work-space poses a logistical nightmare.


The meetings were a bit of “preaching to the choir” as the majority who went are opposed to the cage activities, but it was interesting to hear everyone’s perspectives on the situation.
Charlotte Bates and Diane Smith both demanded to know WHY DoC went ahead and issued the permits. One B&B owner suggested that businesses refuse to accommodate shark tourists, though Mitchell pointed out that could be tricky if the visitor spent five days at a place and then decided to go cage diving on the last day. He also pointed out this could make the Island look inhospitable.
Eamonn Ganley voiced a concern felt by many: ‘The horse has already bolted. The sharks’ behaviour has already changed. How are we going to turn that around?”
Zane Smith responded it could be changed back; and Mitchell replied that we need to try to stop it, as soon as possible, and reverse the damage done if possible.

Paua diver John Hildebrand pointed out that if it is assumed that while a shark boat is operating then dive operations cannot work in the area, that is setting a dangerous precedent for all industries nationwide. Mitchell agreed: ‘It’s ridiculous, it’s like if I open a fish and chips shop across the road from yours and then asked you to stop operating.” John also pointed out that blocking out access to the islands would mean a quota reduction for the paua industry.
Phil Sanford, who had seen a great white at Bragg’s Bay the previous day, pointed out what many long time area fisherman and divers have been saying: the back of Edward’s is a primo spot and why has this essentially been given over to shark cage divers? “They are blocking out use for most of the islands out there – who’s going to want to go paua diving or codding in a small boat now?”


Tabuteau confessed he’d been on the fence about the issue when he came down to the island, and in their caucus some politicians assumed there was more hysteria than reality being reported. But after talking to locals he believes there is a real cause for concern.
Both men are fathers, water-users, and first-time MPs. Micthell has promised to come back to the island for another meeting.
Articles here and here.
And then, there's this.
Community monitoring of shark cage diving operations 

Two Great White Shark Cage Diving Operators (GWSCDOs) were recently granted permits by the Department of Conservation (DOC) to operate in the waters around Edwards Island, despite vocal and sustained opposition from commercial paua divers and a large proportion of the Stewart Island community. Now that the permits have been granted, Stewart Islanders have a strong interest in doing everything possible to minimise the risks that GWSCDOs create for other users of the marine environment. Part of this is to make sure GWSCDOs adhere strictly to the conditions of their permits. DOC can (but doesn’t have to) terminate a permit if any of the permit conditions are breached, including any breaches of the GWSCDO Code of Practice. 

However, the permits don’t require DOC to have observers on all GWSCDO vessels or to undertake any other compliance monitoring. In these circumstances it’s not clear how DOC will detect any breaches of the permit conditions or enforce compliance. The Paua Industry Council (PIC) is therefore urging local paua divers and the Stewart Island community to keep a close eye on the GWSCDOs to make sure that they adhere to their permit conditions and to report any breaches to DOC. This article suggests how GWSCDOs can be monitored by community members and identifies some of the main permit conditions to watch out for. 

Community-based monitoring 
Ways in which the local community can usefully monitor GWSCDO activities include: 
  • Anecdotal information from tourists who have been on GWSCDO vessels; 
  • Observations of changes in shark behaviour around Stewart Island; 
  • Observing GWSCDO activities if you happen to be in a nearby vessel (but avoid interfering with GWSCDO operations); 
  • and Monitoring You Tube and other social media for film clips of GWSCDOs posted by tourists. 
In all cases it is best, if possible, to back up any observations or anecdotal evidence with documentary evidence such as film or photographs. 

Permit conditions to watch out for 
The permits restrict GWSCDOs to operating within 250m of the shore around Motunui/Edwards Island. Any GWSCDOs operating outside this area should be reported immediately to DOC. Shark behavioural change has been attributed mainly to the methods used to attract sharks to the dive site.
Watch out for the following shark-attracting activities, all of which are prohibited by the permit conditions and therefore should be reported to DOC: 
  • Berley which is so coarsely minced that it provides food for sharks; 
  • Sacks of berley hanging from the side of the vessel or from a float or any other device; 
  • Throw baits that are made from anything other than legally obtained fish products; 
  • Throw baits that are pulled into or allowed to drift into the cage; 
  • Use of throw baits before the vessel is anchored; 
  • Use of more than one throw bait at a time; 
  • Use of throw baits after a shark has already been attracted to the boat; 
  • Sharks feeding on or taking the throw bait; 
  • Continued use of throw baits after a shark has taken a bait (if a shark takes a throw bait, no further throw baits can be used on that day); and 
  • Any use of artificial decoys or lures. 
Once the dive is underway, watch out for any diver behaviour that that harasses or is potentially harmful to a shark and also identify any situations where a shark shows signs of becoming distressed or alarmed. In both these cases the dive supervisor is supposed to terminate the dive. 

The permits do not allow commercial filming during GWSCDO trips (separate authorisation must be obtained). 
If you become aware of any commercial filming this should be reported to DOC. 

Other events that should be reported to DOC include all incidents of shark entanglement, shark ingestion of material, sharks becoming trapped or partially trapped in the dive cage, and injuries to sharks. 

Finally, DOC is able to terminate a permit if the GWSCDO causes any “unforeseen or unacceptable adverse effects” on great white sharks. All changes to shark behaviour such as examples of aggression towards people or boats around Stewart Island should therefore be immediately reported to DOC, ideally with documentary evidence. 

Reporting to DOC 
DOC is in the process of setting up a system for members of the public to report any observations about GWSCDOs. Until that process is set up, any observations of breaches in permit conditions, complaints about GWSCDO operations, or shark behavioural changes should be reported to DOC at marine@doc.govt.nz.
It really is a bloody can of worms.
But what riles me most in this communication fiasco is the apparent total absence of DoC, the researchers and the operators. The only viable long-term chance to make this a sustainable industry is to engage the local stakeholders - and on that front, all I can see is a rather abject fail.
Dunno whether it is cowardice or merely stupidity - but they got to do better!

Not impressed!

Marine Extinctions - Paper!

Click for detail!

Finally!

In brief, they postulated that compared to the terrestrial biota, there had been comparatively few - and that after having had a closer look at two controversial species, I could find zero evidence for any marine Fishes that had gone extinct during the anthropocene.
But obviously there has been a grave reduction in numbers all the way to local extinctions, meaning that many populations are now so severely depleted that they have accumulated extinction debt; and having thus lost much of their resilience and faculty to adapt, an environmental catastrophe like Climate Change could well push them over the brink.

And now this is largely being confirmed in this paper.
Synopsis here.
And I cite.
Conclusions 

On many levels, defaunation in the oceans has, to date, been less severe than defaunation on land.
Developing this contrast is useful because our more advanced terrestrial defaunation experience can serve as a harbinger for the possible future of marine defaunation (3). Humans have had profoundly deleterious impacts on marine animal populations, but there is still time and there exist mechanisms to avert the kinds of defaunation disasters observed on land. Few marine extinctions have occurred; many subtidal marine habitats are today less developed, less polluted, and more wild than their terrestrial counterparts; global body size distributions of extant marine animal species have been mostly unchanged in the oceans; and many marine fauna have not yet experienced range contractions as severe as those observed on land.

We are not necessarily doomed to helplessly recapitulate the defaunation processes observed on land in the oceans: intensifying marine hunting until it becomes untenable and then embarking on an era of large-scale marine habitat modification. However, if these actions move forward in tandem, we may finally trigger a wave of marine extinctions of the same intensity as that observed on land. Efforts to slow climate change, rebuild affected animal populations, and intelligently engage the coming wave of new marine development activities will all help to change the present course of marine defaunation. We must play catch-up in the realm of marine protected area establishment, tailoring them to be operational in our changing oceans. We must also carefully construct marine spatial management plans for the vast regions in between these areas to help ensure that marine mining, energy development, and intensive aquaculture take important marine wildlife habitats into consideration, not vice versa. All of this is a tall order, but the oceans remain relatively full of the raw faunal ingredients and still contain a sufficient degree of resilient capacity so that the goal of reversing the current crisis of marine defaunation remains within reach. 

The next several decades will be those in which we choose the fate of the future of marine wildlife.
Indeed, there is hope.
And like I said back then, there is a role, small or big, that each of us can play in order to ensure that the worst case scenario does not eventuate.

And what about the Sharks?
Re-read this report by the IUCN and this paper by Christine!

Let' do it!

H/T The Ambassador aka the Saffron Pimpernel!

Shark Reef - the Party is over!


Recognize the dude?

Yes this would be Whitenose - for obvious reasons!
This is the very first Bull Shark I've named 12 years ago, and he's still going strong! I wasn't on the dive but El Diego who sent me the picture tells me that he was making sure that everybody knew he was back!

Remember what that means?
Indeed - together with the fact that we're not seeing any more fresh Shark bites, his visit officially concludes the very early, and very short mating season!
Now, the action will slow down as everybody quickly assumes the correct rank within the newly established hierarchy - and then we wait. In four-five months, we'll know who's pregnant and who is not, and compare that to our observations from the last five weeks.

Oh, and Alex:
Guess who was there, too! :)

 
Gracias Diego - much appreciated!

Undersea Hunter joins GSD!

The venerable Undersea Hunter and Sea Hunter that were later joined by Argo with its sub.

We are stoked.

This is really as good as it gets.
Having pioneered much of what is today being considered modern liveaboard diving, Orly, Avi and Yosy's iconic Undersea Hunter Group is truly the crème de la crème of the global industry.
Ive spent quite a bit of time diving both Cocos and Malpelo with them and with all due respect (!) to all other operators, I personally consider Sea Hunter one of the best, if not the best liveaboard in existence. And back then, they were also employing arguably the world's best divemaster, Mario Arroyo, and Pepe the skiff driver's friendliness and mastery of the often treacherous conditions are still the stuff of legends.

You can find Undersea Hunter's operator page here.
Once again, this reaffirms GSD as the world's premier alliance of professional, safety conscious, research-based and environmentally responsible Shark diving operators.
And it isn't over yet - more stellar operators will be announced shortly!

Welcome aboard!

Fischer in Australia!

Tagging Tigers in WA - good idea? Source.

Oh yes he's there.

And of course he's already giving the usual breathy interviews.
This is officially being sold as Tiger Shark research - first on the East Coast then in Northern WA. But of course, before even having touched the first Shark, Fischer is already, once again, mentioning beach safety, and making oblique references to GWS.
Because.
Some conservationists and advocacy groups blame the lack of progress on global collaboration. "Northern California, Australia, New Zealand - you have a couple of kingpins reigning over their kingdoms and they don't want anyone to come in because they might not be the king or queen anymore," said Chris Fischer of Ocearch. "They're not really into collaboration, they're not really into ocean or shark first. They're into being the man, or being the woman. So we have to disrupt this...the ocean needs our help now."
As he bloviates in this stupidity.

Right.
It's same old same old.
Fischer the next -and of course bigger and better- Cousteau, the great conservationist, tagging pioneer and protector of public safety - and of course, pinnacle of self effacing modesty, who merely does everything he does for the Sharks!
Barf.

Which of course begs the question,
Which safeguards are there in place so that the stupid government of WA will not be using the data from those newly tagged WA Tigers (and god forbid, GWS!) to go and kill them once they start lurking (yes apparently, that's what Sharks do!) off some beach?
And he's also set his eyes on New Zealand, apparently for this November - undoubtedly much to the benefit of stirring up defusing the delicate situation in Steward Island, see here, here and here!
And yes I'm being sarcastic!

To be continued!

Andrew with his father, the legendary Rodney. Source.

Remember this post?

Sure you do! :)
Therein, I refer to this courageous blog post by Corey Bradshaw where he exposes how the Australian government is censoring and muzzling its scientists. That policy continues to this day, and the sometimes baffling reticence by some members of the Australian scientific community to address the WA Shark cull needs to be weighed against this backdrop - and this is also precisely why the unflinching public opposition by people like Colin and Jessica fills me with particular admiration!

Enter Andrew Fox of GSD.
He too is far from being impervious to the wrath of government that holds sway over the renewal of his licenses - and still, he too has decided to go public against the demented shenanigans in Western Australia.

SRMR - Accolades by Juerg!

Great pic by Klaus!
 
Check this out!

No not because of the personal accolades.
They are certainly nice but irrelevant. But what is really impressive is the sheer number and scope of Juerg's papers so far - and more are in the making as we speak! I should have posted that list a long time ago - but we're currently revamping our website and will certainly add them there!
Interesting to say the least is also the fact that on top of having retracted their support for the GFSC, the SOSF has obviously also ceased to fund Juerg. WTF!
I could comment but choose not to - but it's certainly their loss not ours!

Anyway - very nice!

Bull Shark or GWS?


Hmmm.

Story here.
We find a lot of Bull Shark teeth, and the central ones are perfectly symmetrical like the one depicted - but those GWS do wander from the Atlantic into the Gulf, so one straying into the Bahamas is certainly a possibility. And a bite spanning all the way from the shoulders to the buttocks is very large indeed!

Do Shark Diving Operators need to be regulated?

Commercial Shark feeding - very very safe!

Thorny thorny!

If you're a Shark diving operator, you need to read this!
And I cite.
5. Conclusions 

In recent years there has been increasing global interest in shark-encounter tourism and the potential economic incentive and awareness raising benefits this industry may bring to shark conservation. 
However, recent research has indicated negative behavioural impacts arising from shark diving or snorkelling and inadequacies in management have been highlighted. 

In this global study of shark tourism practices we found that in the majority of cases surveyed, shark operators apply codes of conduct (either mandatory or voluntary) to ensure the safety of both people and sharks even when no formal national guidelines exist. 
However, the practices and approaches taken varied widely, and we believe there is a good case for greater regulation to raise standards and minimise any adverse effects on both sharks and people. Such an approach would involve greater scrutiny of the industry and formalisation of legally enforced national guidelines. 

Links are frequently made between shark baiting/provisioning and attacks, and while these remain speculative, a precautionary approach is warranted that would be best delivered through regulation. 
Without this, shark tourism has the potential to cause accidents which could decrease the growing popularity of sharks and thereby have negative knock on effects for their conservation, particularly when culls follow attacks such as those recently witnessed in Western Australia. 

While our questionnaire indicates that the majority of shark encounters and shark tourism currently pose very little risk to people, more field research is required on shark behavioural responses to tourism practices to help assess best practices for sharks, people and environment. Shark diving management therefore needs to be dynamic and must evolve with continuing developments in the industry and understanding of shark behaviour.
First things first.
When it comes to collecting the evidence and painting a picture of global Shark diving tourism, this paper is really quite good. Also, I really don't want to further elaborate on what I've already said about those problematic non-provisioned encounters with Elasmobranchs, be it Whale Sharks, Mantas and the like, i.e. that if the industry is not able to self regulate, then the regulator has to step in - see e.g. here.

And what about those provisioned dives?
I've blogged ad nauseam about what the evidence teaches us about their effect on the animals, the public and the environment, e.g. here. Yes there are of course people that postulate otherwise - but at this stage in the debate, it is for them to stop speculating but instead, to finally come up with evidence to the contrary. And no, invoking the precautionary principle in view of those totally unsubstantiated allegations aint good enough anymore, either!
And if they cannot come up with the evidence, they finally need to shut the fuck up - especially the researchers!

Yes Shark feeding is dangerous - dooh.
Yes often the Sharks get excited - dooh.
And yes there are dodgy Shark diving operators, and those unsupervised multi-user sites like TB are a cause for concern. And we also all know that there have been quite a number of Shark bites - very few on the clients but plenty on the feeders, the latter ranging from harmless because there was protective gear to serious when there was none.

But here comes the big BUT!
In tens, if not hundreds of thousands of baited Shark dives, there has been a grand total of ONE documented fatality - and I betcha that if one were to make the comparison to "normal" diving, you would likely find more fatalities per hours spent in the water than during baited Shark dives!

The reason?
Believe it or not - but none of us has a death wish, and we also want to bring back our clients unharmed!
We know that what we do is dangerous, and we are the first ones striving to minimize and manage the risks we admittedly create! This is why the overwhelming majority, if not all of Shark feeding operators have devised voluntary codes of conduct - and those protocols obviously work!
Does anybody really believe that some government bureaucrats could come up with, implement and then supervise better protocols - but more importantly, is there really a need for them? There are already more than sufficient laws on the books to deal with criminal negligence vis-à-vis the customers, and accidents to the staff are covered by occupational health-and-safety regulations - so instead of wasting additional government resources on what is essentially a non-issue, why don't we rely on the authorities to simply apply the Law.
And guess what - when the incidents are serious, they incidentally do it already!

And the suggestions by the authors?
... legally binding national guidelines for shark tourism which all shark operators need to be made aware of. 
Education could include mandatory classes for shark operators about species which are likely within their area, the threats facing them, current management practices, potential human impacts from tourism activities and best practice for mitigating them. Attendance at such sessions could be a formalised requirement of any permitting scheme and could be funded through charges to operators. Based on our findings and review of literature, we propose that national regulations or codes of conduct for shark-related tourism should include limits on: group sizes, time spent in the water with sharks and provisioning (both in terms of quantity and quality of food items). There needs to be compulsory education about such regulations and legal consequence should they not be followed.
Seriously - what a load of crap!
Surely, this stupidity has not been coordinated with the concerned operators - or has it?
None of the accidents I know of (and I know of many!) had anything to do with group size, time spent in the water and amount of food, let alone with not knowing the animals! Once again, it really appears that some researchers are bloviating about our industry without the slightest clue about sustainable Shark provisioning let alone tourism - and it is really starting to piss me off!

Guys, we appreciate the interest.
But for fuck's sake, as a minimum, you need to talk to us before accusing us of not knowing what we do! In fact, the contrary is true - most of anything that is known about Shark behavior and sustainable tourism practices has been garnered on dives that have been established by our industry, and smart researchers have long learned to talk to us and to listen to what we got to say!

Anyway, it matters not.
Governments got no time for these minutiae - that is, unless there are real issues where self regulation has obviously failed. Then they should, and will regulate - and when they do, I'm equally confident that they will seek the dialogue with us, the pros!

And in the meantime, we will continue to do what we do best.
We will continue to provide extremely safe, enjoyable encounters that harm nobody - not the public, not the Sharks and not the environment. And we will of course evolve and progress, like we always have, and like we are presently doing by having voluntarily established GSD and quite possibly, by collaborating with respectful people and organizations in formulating a global code of conduct like briefly mentioned here!
That's how you do it - by dialogue, not by proclamations ex cathedra!

To be continued no doubt!

PS: Martin here. PIDOOMA huh - hahahaha, very funny!

Sharkbanz - total Scam!


Then I was merely making fun of it.
But now it is being sold to the public, and this is just simply egregious.
Shark attack survivor Paddy Trumbull, 65, who had her buttocks torn off by a bull shark in Queensland in February 2010 said such a device would have 'absolutely' prevented her attack.
The poor woman got no clue and is obviously being used.
Passive electrical repellents – permanent magnets 

Possible alternatives to EPM repellents are permanent magnets, which are thought to act on the electrosensory system indirectly through electromagnetic induction (O'Connell et al. 2013c), which is the same physical mechanism that is thought to allow sharks to detect the earth’s magnetic field (Kalmijn 1978; Kalmijn 1982). Both ceramic (barium-ferrite) and rare-earth type (neodymium–iron– boron) magnets have been investigated as possible shark repellents (O'Connell et al. 2013c). Ceramic magnets are comparatively cheap and do not degrade in seawater but are relatively weak (typical residual flux density 2,000–5,000 gauss (G), ASTM 2007) compared to rare-earth magnets. 

Therefore, larger ceramic magnets are required to provide a given magnetic field strength. Rare-earth magnets contain EPM elements that degrade in seawater and are more expensive than ceramic magnets but are considerably stronger (typically 8,300– 14,100 G, MMPA n.d.). Given that the earth’s magnetic field (~0.5 G at the surface) is thought to be capable of inducing electrical potentials in ocean currents (50– 500 nV cm-1) that would be readily detected by the shark’s highly sensitive electroreceptors (detection threshold ≤5 nV cm-1; see above), strong permanent magnets are probably capable of inducing large potentials that would be quite unlike anything encountered by sharks in their natural habitat. Sharks are clearly able to detect and respond to strong magnetic fields. Stroud et al. (2005) showed that juvenile N. brevirostris, C. limbatus and G. cirratum could be aroused from a state of tonic immobility by magnetic fields of about 50 G, generated by moving a 10,000 G rare-earth magnet within 10-20 cm of their head. Rigg et al. (2009) demonstrated that free-swimming captive sharks, including S. lewini, grey reef sharks (Carcharhinus amblyrhynchos) and Australian blacktip sharks (Carcharhinus tilsoni), react to static magnetic fields greater than 25 G at distances of 0.26– 0.58 m by swimming faster or turning away from the source. 

However, studies investigating the ability of magnets to protect baits from depredation have provided conflicting results. 
Captive S. acanthias and wild C. galapagensis displayed behaviors suggestive of irritation or aversion when encountering small rare-earth magnets attached to tethered baits, but the presence of the magnetic field (4–1475 G in the case of C. galapagensis) did not significantly reduce the overall likelihood of depredation compared to controls (Stoner & Kaimmer 2008; Robbins et al. 2011). In contrast, O’Connell et al. (2010) showed that G. cirratum avoided bait protected by a C8-grade barium–ferrite 27 magnet (150x100x50 mm; residual flux density ~950 G) compared to baits paired with a nonmagnetic clay brick control. Smith and O’Connell (2013) found that S. canicula actively avoided baits protected by an N52-grade neodymium rare-earth magnet (20 mm diameter  30 mm height; residual flux density ~14,000 G) compared to baits associated with a lead weight control. Mixed results were also obtained in a dual longline and hook-and-line study (O'Connell et al. 2011b). Shark catch rate on longline gear was not reduced by the presence of strong (14,800 G) neodymium magnets on the hook shaft but was significantly less than controls (bare hooks or hooks with a lead weight on the shaft) when using weaker (3,850 G) C8 barium–ferrite magnets (O'Connell et al. 2011b). 

The repellent effect of the barium-ferrite magnets was also species-specific in that they significantly reduced the catch of C. limbatus, but not of C. plumbeus, N. brevirostris, and other species. 
Using hook-and-line gear with either a magnet or lead weight control attached directly to the bait rather than the hook, strong neodymium magnets did result in a reduction in the catch of M. canis and R. terraenovae, but not S. canis. In a further example that the repellent efficiency of magnets and other deterrent technologies is highly species-specific, field trials with C. carcharias show that tethered baits protected by a strong ceramic magnet were actively avoided and eaten significantly less frequently than baits protected by a non-magnetic clay brick control (O'Connell et al. 2013a). In an attempt to combine both EPM and magnetic repellent technologies, a so-called SMART™ (Selective Magnetic and Repellent-Treated) hook has been developed that generates a voltage of up to 1.3 V when immersed, as well as a magnetic flux of 80 G, and has been shown to reduce the catch rate of S. acanthias on longline fishing gear (O'Connell et al. 2013b). The fact that the relatively weaker magnetic fields generated by barium-ferrite magnets and the SMART hooks are more effective in reducing depredation across these studies, rather than stronger fields generated by neodymium magnets, highlights the need to establish a repellent ‘strength’ that is optimally effective rather than just opting for the maximum that can be generated.
Long story short?
Some Sharks do react, some don't - but when they do, it only happens at very short distances, meaning that a band worn on the wrist or ankle would certainly not have prevented that bite on the buttocks - nor would a band worn on one's wrist prevent a bite to the other hand let alone the torso and legs, etc etc. And in addition to the differences among specie, there are also differences among regions and of course, individuals!
You get the gist - an of course those bastards know it all too well!. 

And this so-called ultimate test?
Watch.



See what's happening - those target areas are tiny!
Here's a test for you the would impress me: build a two meter long chumsicle, insert a band at one end and then throw it to a pack of Sharks!
Any bets as how much of it would be left?

This is abhorrent on so many fronts.
The whole bloody marketing campaign is callously using images like these ones to con the public; the whole thing is nothing but a cold-hearted scam; and it may ultimately suggest to people that they are now bullet proof, meaning that there is a real risk that wearers will start throwing away common-sense precautions and engage in riskier behavior.

I say, shame on the Garrisons.
They're either totally naive or total hypocrites.
And especially, shame on the researchers from Shark Defense who are accomplices in this shameful travesty! But we've seen that one before haven't we - pecunia non olet all over again!

To be continued - alas!
