I went to the Georgia Aquarium a couple of weeks ago and was disturbed by the cetaceans kept there-4 belugas, 4 common dolphins-in what I consider very confined displays. The Aquarium as well has 4 whale sharks! The dolphins performed 365 days a yr in their one and only indoor show. Admittedly I have had concerns for cetaceans "shows" for quite a long time and even keeping these animals in captivity. Knowing that orcas dorsal fins atrophy in captivity is a sure clue that something is very wrong--the first time I noted this was when I watched Free Willy in the movie theater a long time ago. I will also add that the aquarium's wave display for reef fish is WAY overstocked with frantic fish darting about. Particularly notable are small yellow tanks (there was probably more than 100 of them in the tank) in addition to many other species.
Anyway, following my visit, I did come away troubled. Started locking around online. Ran across Blackfish and watched it. The documentary is very obviously a one-side advocacy in favor of not keeping orcas in captivity, particularly having them as performers. However, pictures don't lie and the documentary captures some heart-rending clips. I came away knowing that keeping these creatures, and other cetaceans in captivity is wrong, and even more wrong to turn them into circus animals. There is a reason that circuses are pretty much obsolete now, so its time to start thinking along those lines for sea mammals as well.
I am not anti Sea World. Sea World is a zoo, and I am not anti zoo either. Zoos have made great strides in our understanding and appreciation of animals, not to mention contributed to the conservation and preservation of vulnerable species such as the panda. Sea World has invested its business model on their animal shows and they aren't just going to give that up. They can't and survive. Yet, lets hope that they are forward thinking about this and make a concerted effort to move away from these shows. This will be very difficult as they have a lot of mammals now, who are very expensive to take care of. How will they manage to take care of these animals if they do not represent a profit for them?
