  1. Hello Everyone ! This is not a Dive Trip as it is open all year round, but I though it was the best place to mention it as it is a heaven for underwater photographers. The Awakening Shark Dive runs from Barefoot Kuata Resort on a small island in the Yasawas, Fiji. It was created with sustainability and conservation as inseparable from any diving activity. The latest available scientific recommendations and experience from dive site around the world were collected to create a dive that is good for the sharks, for the reef, and for local communities. Extensive briefings allows you to learn more about sharks before you jump in the clear water offshore Yasawas islands. The dive has been setup to be easy for beginners and in fact, you can join us on our isolated island even if you never dived before, learn in a few day and jump in with the sharks. No deep-water, no current, helpful staff, so it feels as easy as any simple reef dive - but don't be fooled, it's a blast for experienced divers too ! The Dive is Photographer friendly and always try to give the best spots and angle for photographers. The dive can also be booked exclusive for one of few person, allowing more freedom and unique angles to see the sharks. There are also multiple dive sites around the resort, from shore dive in Marine Protected Area (including night dives) to deeper sea mounts, caves and tunnels, walls or simply nice and easy shallow coral reefs. You can also decide to spend the rest of your day at our pools, bar, or hiking the mountains of the islands ! In the water ? Massive well-educated bull shark swimming in front of you in a totally safe experience. We often hear "it's the best thing I've done in my life !" Find more with this presentation video : https://youtu.be/B2R_bQxaEr8 Here is the website : http://www.thebarefootcollection.com/diving/awakening-shark-dive.htm Or email : sharkdive@thebarefootcollection.com And a few photos from the dive : Contact sharkdive@thebarefootcollection.com for more information, booking, special groups or any other question !
  2. Acoustic tagging is not the same tool. It's very different and should be complementary when it can be used at all. The reason is that you need recievers to "record" the shark. The range is generally ~200m. You will have 0 information about where is the sharks when he is away from of the those recievers, which make it poorly informative in the case of pelagic/semi-pelagic sharks. It is a great tool for resident sharks however, because it will give you information about the daily routines of sharks. But of no use to learn about long migrations, deep sea uses, etc... edit : hope it don't go controversial but we did a quick recording in 2011 on a grey reef sharks - very easy sharks as they are very robusts. This is internal accoustic tagging. One could say very invasive but we have over 12 months cool data about their roaming around healthy : ) notice how thick the skin is on females. (and the divers under us at the beginning - if I remember well it was Bill Gates. We had James Cameron the next week ^^)
  3. I realize how glad I am that I'm mostly working with small robust sharks. Harder I've deal with so far are bull sharks that get tired pretty fast - you have to work really fast and make sure you release it is shallow waters in case he needs some help... some tonic immobility before release makes a big difference, they seem to "forget" what just happened and go back very peacefully. http://farm3.staticflickr.com/2441/5856937157_1a5dcc4fd2_z.jpg For the question about "do we need to catch GWS to tag them?", I guess it depend on several things including where you are (i.e. how clear is the water, can you approach GWS underwater without too much risk) which make it harder when you are elsewere than at Guadalupe... I think I remember there is great job being done in south Australia / New Zealand with some really cool large boat designed for GWS which allow fast and easy catch and release.
  4. (BTW, if I remember correctly, the Quensland alone is killing on purpose over 600 tiger sharks a year just so there is less chance that an accident happen. A illegal fishing vessel with 4 tons of sharks have been taken in new caledonia less than a month ago, and it's not the first time it happens. and there is more example like that all around. I understand it's important to watch that no organisation is doing bad things, but these hundreeds of deaths should be more in our focus)
  5. In a perfect world, everyone would understand that sharks need to be let alone, no one would overfish or even fish them, and we would be totally fine no knowing where they go. However, this is not the world we are living in. Sharks are killed. It raises concerns, and politician are listening to both sides : one that say "we are feeding people, making money, paying people to be fishermen, sharks are just fine we still catch a lof of them and when we don't we will stop anyway because it's not gonna be lucrative anymore and then they can recover" and then there is the people that don't want sharks to be killed. I'm one of them, and we have to "counter" the argument made before. We have to make politics understand that what "killing sharks" bring to society is not as important as "not killing sharks" is. In this world, we can't say "look they suffer", or "poor them they die". It just doesn't work. Politics don't care. We have to come up with solid argument and data and prove to politics why, without a doubt, they should trust us more than them. And doing so it happening through science. Now, it does not justify bad methods, and I am not saying that we have to kill a few to save many - I wouldn't do it because we don't know if we are going to save many in the end. I do not comment on the Ocearch as well, I don't know enough about them. What I can say however, it that catching sharks (hooks, nets) is the only way we have to do some sort of science on them. Tagging and genetics, which are used a lot today, both needs catching sharks. Because older scientist have been experienced shark catching, we learned a lot of tricks to make it easier for the sharks. I.e. circled barbless hooks, which species are the less resistants, how to handle a juvenile without hurting him, why you should not drag a heavy shark by the tail on a beach, etc.... All this techniques allows, if you follow the rules, to make it less stressfull for the sharks. At least for the "easy" species, you can catch and sample /tag individuals quickly enought to make sure there is no dammage, that he go back in the water just fine, and that he'll be here on his routine the next day. So, I guess the original message was : does Ocearch follow these rules, or do they unecesarly (i.e. for TV / to be cool or whatever) hurt sharks ? rather than "is sharks science a good thing?". Catching a shark can be stressfull for him, but if you do it right he'll be just fine. The only problem is, how "right" do you do it.
  6. No : I bought a new one recently, no vignetting as well. (however I do have vignetting when using this one : http://uwcamerastuff.com/precision_5_dome.htm ) maybe it's fine with the 5D2 because the combinaison of everything (housing included) makes it work. It might not be the case for other full frame combo.
  7. Christine - 5D2 + sigma 15 I have the ikelite with the : #5510.45 Dome Assembly and #5510.11 port body Absolutely no vignetting. You should double check this information. If you need a raw file taken with it, just ask. Best, Thomas
  8. (I have a 5D2 with Ikelite and the Sigma 15 : no vignetting with a large dome. awesome fisheye lense.)
  9. We are using energy, time and power to speak about this. They don't even deserve it. They'll grow when they'll be ready for it. We can't blame a baby that can't walk, and for the same reason, just look at this kind of people with a sweet smile and then ignore them : )
  10. Great ! remind me a serie I did back in the days. Always nice to see how much animals don't care about you when they are doing serious stuff : http://farm4.staticflickr.com/3081/2619242872_f810253248_o.jpg (sorry for the bad english)
  11. I actually think the black and white stripped surf board could make a small difference in decreasing the risks. It have been show in the past that sharks swim away really fast when they meet a simple fake killer-whale. In shallow dirty waters it might make no difference, but since it's cheap to paint your own board, why not. Just don't pretend it's for camouflage, a man won't camouflage in front of a shark. : )
  12. Hi everyone I recently saw this video. I was wondering if any of these could be applied to UW cameras : - add an extra protection in case of flooding - use it on your dome for under/over shots - use it on yourself/ your fins to get extra power swimming - use on the housing to limit the salt contact and other ideas ? : )
  13. There is no shark fishing in French Polynesia. It's forbiden and applied since 2006. There never was much fishing before that anyway. That's why it is one of the last shark's eden ! However, you might need to know the right spots to make sure you see a lot of them !
  14. Would do a great print ! I feel it could even get more negative space on the left to do a "panorama-like" giant print : )
  15. Whaling operator kills. I'm just saying, catch and release for science purpose can be a good thing, as well as chuming. There is many discussions and argument in this way that already exist, and we are finding, thanks to catch and release, genetics, tagging, many things that told communities how to best project sharks, or how do they live, etc... That said, once again, I'm FOR the banning. Here is a screenshot of a publication I recently did and wrote : But I could do and writte it because I caught and release sharks, hundreeds of them.
