Happy Holidays from SharkDiver.com!

It's kind of a tradition here at Shark Diver posting this image.

It features a shark we named in 2004, "Shredder," with the image shot by Christy Fisher.

This image serves as a reminder of all the shark diving folks, research folks, and media folks we have come to call friends over the years.

Good people who have made the business of shark diving and shark conservation a very exciting place for us.

We are honored to know these unique and special people and look forward to the new decade of shark diving adventures, discovery, and conservation with you all.

Farewell 2009 and very Happy Holidays!

Dr. Sylvia Earle's Deep Search Foundation - Whale Sharks

Isla Holbox is perhaps the best known commercial whale shark encounter sites on the planet. A surprising success story of commercial shark diving and growing site research and conservation.

With little known about these "gentle giants" a scientific expedition lead by Dr. Sylvia Earle's Deep Search Foundation chronicled it's time here from July 11th - 15th, 2009 in an in depth series of blog posts.

Great reading for those desk bound shark adventure seekers.

About Deep Search Foundation

Founded in 2008, Deep Search is dedicated to exploring and protecting Earth's ocean, the cornerstone of our planet’s life support system. More than 70% of Earth is covered by ocean, and 94% of our habitable space is in the seas. Yet, we have explored less than 5% of the ocean and protected only a fraction of 1%. These figures pale even further when one considers the deep sea.

Goblin Girl on... sharks in captivity!

Ok, I guess I SHOULD comment on the EU plan of action for sharks that was released on the 5th of February, but since both my hard drive and I decided to crash on the same day (no worries, it was just a cold for me and I had a recent back up of my hard drive so I didn’t loose that much data), I haven’t had the time or energy to go through it yet. I will return to it later.

So, my blog today will be about sharks in captivity. I have to admit that I have a very split opinion about this. Or maybe not… Let’s say I have an opinion. Here it is:

I love sharks! I love to swim with them, dive with them, watch others dive with them on tv and I like to see them ”live” in aquariums. For you, it might be the last statement that is the hardest to understand (since this is a blog which I guess mainly people who likes to go diving with sharks read. I often meet people who think that it is crazy to go diving with sharks!).

All my holidays I tend to plan so that I will either be able to swim with sharks or see them in nice aquariums.

But - there is always a but - I want the sharks to be healthy in the aquariums and I like diversity above ”mass consumption”.

I realize that any aquarium most likely is too small to be an ideal place for a shark. They should be allowed to swim freely in the ocean. Still, I think that letting people see sharks with their own eyes makes them more willing to help saving them. Sharks are not as easy to love as a seal pup or a smiling dolphin (I don’t know about that really – I have loved sharks ever since I could talk, but many people tell me about their fear of sharks). You have to work harder to make people as aware and fascinated as you are yourself. One way is to show them sharks on tv, an other to have them on display in aquariums.

But not all aquariums are ok. The film clips below were shot in Denmark. So far that is my favourite shark aquarium in the world. I guess the tank is a bit crowded, but the sharks look fine. No bruises or nasty wounds, no strange swimming patterns and a high diversity. I’ve been to several aquariums in the US where there have been lots of sharks – in fact, they have been lying in droves – but just 2 or 3 species. Those aquariums have not impressed me at all – although the sharks look ok. I don’t know if it’s because we in Scandinavia have to buy all our tropical sharks and ship them for lots of money to our aquariums – and therefore we can’t afford to overcrowd our tanks - whereas aquariums in Florida just go out with some fishing gear and takes as many sharks as they want. It could be that the sharks give birth to pups in captivity as well, but monocultures are boring and makes me a bit sick.

I went to a shark aqaurium in Germany. The tank was big and not too crowded with the four sandtigers that they had, but it also contained a poor lemon shark that was swimming in circles just above the floor. You could see a circle in the sand where it had been spinning around. That was very sad to see! Especially since I have since learned that you can cure this behavior with the correct medicine!

There is an other reason why that dive below was so excellent. As a biologist I know that nature is unpredictable. You might pay a lot of money to go very far away to end up with… scrubbing the boat from fishblood and not seeing a white shark for a whole day (that happend to me in South Africa in 1995). In an aquarium I know that I will have sharks around me – for sure! Also, since I took up diving I became what we in Sweden call an “ear child”. After a few dives I get ear infections and are not allowed to dive anymore for a while. If you spend a lot of money to go on a diving holiday you don’t want to get ill! Especially not before you have seen those sharks! Luckily I can snorkel ok and many sharks prefer that, but still there are some adventures where you will have to dive to see the sharks. The hammerheads off Cocos Islands are at the moment just a dream dive for me.

So, do I think that it is ok to have any specie of sharks in captivity? No I don’t think so. Some species adopt better than others to being held in captivity. That said, given the chance, I would gladly watch the captive whale sharks in Georgia, the white sharks that they have had in Monterey and the goblin sharks in Japan. I know it’s not politically correct, but if that is my best chance to see them “live” at all, I’m in.

In the best of worlds I would just have to grab my snorkel and jump into the water and be surrounded by sharks. For me here in Scandinavia, it isn’t as easy as that.

P.S. Since over 18 years I share my life with a pet tarantula. Yup, 18 years. In the wild, she would probably not have lasted more than a few years. Now we can look forward to say, 45 years together… Sometimes the sharks might be safer from predators – like humans - in aquariums… D.S.

Farallons White Shark Tours-Add One

On the subject of shark diving...looks like there's one more white shark watching tour option for thrills seekers here in Northern California, Silver Fox.

We got an email from a diver this week asking about these guys, our response was they are new to us. Great White Shark Expeditions have streamlined the experience and do not offer caged encounters, cutting the cost down to $275-125 for the day and relying on natural predations for the actual shark viewing. Other operations have cages, but they are not allowed to chum or tow decoys, so they too are relying on natural predations. We wish the new guys luck:

Witnessing a very large great white shark consume a 300 lb. sea lion can be a very dramatic experience. These particularly violent acts are as natural as the rising of the tide for the shark.During the Fall months (Sept – Nov), thousands of marine mammals migrate to the Farallon Islands, which are approximately 27 miles from the San Francisco Bay to breed and calve their young. This event attracts the largest great white sharks in the World. The Farallon Islands, located in the red triangle, are the known feeding ground for the great white sharks before their long Pacific Migration. We have had many dramatic encounters from great white attacks from the safety of the vessel. These events are purely natural and part of everyday life at these islands. This is an event that is truly unforgettable.
