Oh well.
It is finally slowly departing.
And for you who have asked: Thank You, we all are well and normal operations will resume shortly, hopefully early next week.
Let's go Shark diving!
Blog about "The World's best Shark Dive" by Beqa Adventure Divers. Featuring up to eight regular species of Sharks and over 400 different species of fish, Shark diving doesn't get any better!
she stated clearly that this was an accident and not the result of human negligence. She also stated that the vessel’s cages are compliant with regulatory requirements and that the crew did everything possible to save the shark, while ensuring the safety of the divers. She did everything, ethically and professionally...!And then there would be little media man Mauricio.
FYI Re: Cage design, I found that shark penetration problems are largely resolved in the positioning, or complete removal of the (trapping) VERTICAL bars within the viewing/camera gaps ... in particular in the corners. Our vertical bars are centrally positioned in the viewing gaps and nosey sharks slide out sideways through the corners.
The sad thing is that the uproar created around this incident does affect shark cage diving around the world, a non-consumptive tourism activity, whilst shark demersal longliners are decimating our shark populations and this where the focus should be. In South Africa, we are seeing a real impact on our shark populations and even our protected white sharks are accidentally caught, but not reported. If only the social media warriors would not be hypocrites and focus on the overfishing versus cage diving which in South Africa is the only official monitoring and conservation of this species taking placePPPPPPPPS - more pathetic xenophobic showboating, and outright defamation by Allende here.

Repetitive Aerial Gaping: A Thwart-Induced Behavior in White Sharks
WESLEY R. STRONG JR., in Great White Sharks, 1996
Causation
Baits pulled away travelled horizontally, just beneath the surface until they came against the hull at which point the sharks generally turned away. In the vertical baiting configuration, however, the bait could be hoisted directly out of the water as a shark tried to seize it, moving it out of reach more quickly than a bait drawn horizontally. This distinction is important, because 11 of 15 (73%) RAG occurrences were elicited while using the vertical baiting technique, but the technique itself was employed less than 5% of the time.
In each case, RAG followed a series of failed attempts to seize a bait and was immediately preceded by an open-mouthed lunge and miss as a bait was withdrawn. Lack of contact with prey after the feeding MAP was initiated appears to play a role in triggering RAG, but does not solely explain its onset. One factor common to each observation of RAG was that a portion of the anterior buccal cavity was exposed to air before (i.e., during the surface lunge) and during its execution. While failure to obtain food while submerged may eventually evoke a similar response, we never observed an underwater bout of RAG during more than 135 hours of underwater observation. Thus, it appears that contact with air is required to initiate the response.
Personal Shark Deterrents
A growing number of personal shark deterrent devices are commercially available.
Some are intended to be worn while others are to be attached to surfboards or similar equipment . The deterrents fall into two main categories: electromagnetic (EM) devices and camouflage.
The EM devices include active (battery powered) and passive (permanent magnet) types that are either worn or are attached to surfboards. Camouflaging patterns are either wearable (wet suits) or applied to surfboards (decals, paint).
EM shark deterrent devices are all based on the same general principal, but they are not equally effective. “Sort of works” versus “doesn’t work at all” are both real possibilities and independent evaluations and comparisons of EM devices that are superficially similar are important...
The evidence for the efficacy of camouflage, whether worn or applied to a surfboard, is limited and inconclusive. We note that claims for camouflage tend towards statements that the swimmer or surfer is less likely to be noticed by a curious shark that just happens to be swimming in the area. This as opposed to statements that the camouflage will prevent the attack of a shark that is actively hunting for a meal.
The existing research suggests that some of these devices may be somewhat effective some of the time....We would always keep in mind that none of these devices provide anywhere near 100% protection under any realistic circumstances.
Finally, from a large shark already on an attack trajectory, arguably none of these devices will provide any meaningful protection at all.
Of the shark detections reported by CB, only ~40% appeared to actually be sharks, while ~60% were other objects, most commonly the baited video stations, which were stationary, or schools of smaller fish, which were moving. Of particular note, when, according to the video record, sharks were present, CB accurately detected them only ~40% of the time and failed to detect them ~60% of the time....
Additionally, lifeguard divers swimming in the CB array to clean biofouling off the sonar transducers were continuously tracked and continuously identified throughout the dive as large sharks. Such misidentification might apply to swimmers or seals, clearing the water unnecessarily....
Unfortunately, the documented performance does not remotely approach the promise of the system.
This creates a danger that swimmers and surfers in the vicinity of a system will relax their vigilance and fail to consistently follow safe practices, assuming that this system is protecting them to a far greater extent than it does. It should also be recognized that, even if the system does provide an accurate warning, the shark is already very close to the beach...
No single alternative or suite of alternatives that can 100% guarantee the safety of individuals who choose to enter the water.
- Since no mitigation alternative can provide 100% safety, reducing the chances of unprovoked attacks on humans requires a strong commitment to education and outreach, which can result in the adoption of behaviors that may reduce the risk of an unprovoked shark-human interaction.
- If water activities are avoided, the risk of attack is effectively eliminated.
- If water activities are not avoided and best management practices and Shark Smart Behaviors are widely adopted, the risk of attack may be reduced, but not eliminated.
- All individuals choosing to engage in water activities should think carefully about the level of risk associated with their preferred activity, and be comfortable with that level of risk before choosing to enter the water.
- The decision to enter the water and assume the risk of shark-human interaction is made at the sole discretion of the individual.
Yes. I reviewed it as did Will White.
They did a pretty thorough job with the taxonomy, though whether it’s worth changing the species name is open to debate me thinks.
While widespread success in recovering elasmobranch populations is some time away, scientists, advocates and managers need to be prepared for societal conflicts that may arise when and where it does occur. In particular, implications for current and future conservation management need to be considered as part of conservation strategies in the context of how humans will interact and potentially compete with recovering species.
This will require, from the outset, increased public education and outreach regarding the potential future implications of conservation success and strategies to reduce conflict in order to avoid negative responses to successful conservation outcomes or the thwarting of future conservation endeavours.
