Do we need a shark cull at Reunion Island?


Instagram 
After a recent deadly shark attack at Reunion Island, world renowned surfer and conservationist Kelly Slater has called for a serious daily shark cull.

Grind TV writes "After the 20th shark attack off Reunion Island since 2011 occurred earlier this week, the world’s greatest surfer made a comment that “there needs to be a serious cull on Reunion and it should happen everyday.”


The attack happened at a spot that is well known for it's sharks and there are signs warning people that it is closed for waters ports. Unfortunately those sign were cut down the weekend before, but the local fishermen reported that they warned the body-boarders.

Sky news writes: "It is reported young people had been there for several days, despite being warned by locals of a shark."
Kelly Slater's response to this attack is this. 

“Honestly, I won’t be popular for saying this but there needs to be a serious cull on Reunion and it should happen everyday. There is a clear imbalance happening in the ocean there. If the whole world had these rates of attack nobody would use the ocean and literally millions of people would be dying like this. The French govt needs to figure this out asap. 20 attacks since 2011!?”

First off, I want to extend my condolences to the friends and family of the victim. This is truly a tragedy and the fact that I don't blame the sharks is not diminishing that fact.

I think Kelly Slater is one of the good guys and I admire a lot of the things he does. In this case, I have to respectfully disagree with his stance. By all accounts, this location is well known for it's shark population and the associated danger to water sports enthusiasts. The surfers and body- boarders were warned that those areas are closed to water sports and they still decided to go into the water.

There are tons of places, all around the world, where it is safe to go into the ocean, so why would you want to kill the sharks that seem to aggregate in this area, so you can have another spot? There are relatively few and well known areas, where sharks are found in larger numbers. Why go surfing there? Calling for a shark cull, because someone ignored all the warnings is not the way to protect the oceans. Are we calling for the top of Mt. Everest to be cut down, because people die of hypoxia there? There are always people that want to take risk. Don't blame the sharks when things go wrong.

Also I want to put things in perspective. There have been 20 shark bites since 2011, 8 of them fatal. That amounts to about 3 bites and a little more than one fatality per year. While each death is tragic, there are a lot of other things that are far more dangerous without anyone doing anything to mitigate the danger.

Kelly, I hope that you change your mind on this. A lot of people listen to you and respect your opinion. It's not just about Reunion Island. If people think that shark culls are a good option, there will be calls for those in a lot of other places. I would like to invite you to be my guest and come out with us to experience what these sharks are like when you come face to face with them. Maybe that will change your mind.

Cheers,

How many Great White Sharks are at Guadalupe Island?


Instagram 
The last 2 seasons at Guadalupe Island were awesome with more sharks than we have ever seen before. On some of our expeditions we saw over 30 individual sharks. Some of those sharks were old "friends", while a lot of them were new. We started the 2015 season with 170 identified great white sharks and ended with 200. That was one of the largest number of new sharks we encountered, since we started cage diving in 2001.


We are still working on a final count for the just finished 2016 season, but we definitely have more than 20 new individuals to add. The last couple of seasons were not only very productive as far as the total number of sharks seen (both new and already identified), but it was also unusual that we saw a lot of juvenile females early in the season and generally a much larger number of sharks late in the season. In seasons past, we saw the really big females in October and November and when they showed up, the smaller sharks stayed away.  The last 2 seasons the smaller sharks stayed around, when the big females arrived. What will we see this coming season? We never know what to expect when going to Guadalupe Island, but after 16 seasons of diving with these sharks, I can't wait to go back in August.


This last season was extremely unique in that we saw all sizes of sharks together. Anything from a small 8ft. male to Tzitzimitl and Scarboard, two of the largest females at Guadalupe Island.

Why are we seeing these sharks in larger numbers? Are the conservation efforts paying off? I don't really have an answer to this, but hope that the continued efforts of the Marine Conservation Science Institute, (MCSI) with their tagging and photo ID program will provide the answers we are looking for.
If you would like to support the ongoing research, MCSI has various ways you can become involved, including the right to name a shark. Wouldn't it be cool, if you watch shark week and see a shark you named? You can contact them by clicking here.

Lucy, one of our regular females, easily recognizable by her tail.
We also have 3 science expeditions to Guadalupe Island, with Nicole Nasby-Lucas from MCSI. These expeditions are a great opportunity to learn from the scientist who is maintaining the photo ID database. You also get a copy of that database, so you can identify all the sharks you'll encounter on the trip, as well as the sharks you see on shark week.

To join us on one of our trips, call 619.887.4275 or email staff@sharkdiver.com for more information.

Let's go shark diving!

Do shark repelling devices work?


Instagram 
We see a lot of devices advertised that claim to repel sharks. The question is, do they work?
A lot of these devices use either electricity or magnets that are supposed to repel sharks, others claim that a certain color pattern will prevent a shark from biting the wearer.

I have always been skeptical of these devices, since I have seen sharks been simultaneously attracted to and repelled by the same object. Some of the makers of these devices use videos that show sharks jerk away from their gadgets in their advertising. (just search for shark repellent on youtube) In my experience, anything that causes a reaction by a shark, even one that shows it jerking away and taking off, is also peaking its curiosity, which could mean that these devices may actually increase your chances of getting bit.

I have seen 3 white sharks swim in to investigate a beach towel that got blown overboard. All of them jerked away and took off. While 2 took off for good, one came back, jerked away again, but kept coming back. I don't know weather it eventually bit the towel or not, because I lost sight of them, as they descended too deep to see. It definitely did show though, that even if something causes a shark to take off, it can also peak its curiosity and bring it back to investigate.

Now we have proof that at least one of these devices definitely does not work. The Daily Mail reports that a surfer in Florida got bit while wearing the "sharkbanz"

source

The article states that:
"A teenager has been bitten by a shark while wearing the new shark-repelling band he got for Christmas for the first time. Zack Davis suffered a huge bite to his arm while surfing near Avalon Beach State Park on North Hutchinson Island in Florida. The teen was wearing a new band with magnetic technology that claims to repel sharks away from swimmers." Read the entire article here

Of course I'm not the first to say that these devices don't work. DaShark has called it back in January, when he wrote "Sharkbanz - total scam" You can read his what he said here

Don't get suckered in and buy these products. At best, they simply don't work and at worst may actually increase your chances of a shark encounter.
