Pray tell, what have you learned?
Frankly, I'd prefer to give them a shot at survival in the wild over starvation in a pen. But that's me
At my shark conservation class last week I learned that about 85% of the worlds shark population has been taken by shark finners. If the worlds shark population continues to decline at the current pace that it is, then the reefs and reef fish will soon follow. Did you know that all groupers and many marine fish are born female? they change to male when the need arises for one. it's called sequential hermaphrodism. once they change there's no going back. it takes a grouper approx 25 yrs to reproduce so the fact that they are fishing and taking young grouper also means that they are in jeopardy along with many other species of fish. I am not a Marine Biologist and most of them have forgotten more than I could learn but the Ga Aq is a fascinating place.
Whale sharks are not mammals by the way, they are fish. Not to split hairs or anything. They also can not eat anything larger than a quarter, they are filter feeders. Their diet at the aquarium consists mostly of krill and shrimp. They would never starve at the aquarium, they get fed approx 30 lbs a day, each.
Millions of pounds of unwanted fish are caught each year in gill nets, it's called by-catch. Most of them die and are then tossed back into the ocean. If there is any thing that is wrong it's not that they have 4 whale sharks in a "6.3 MILLION GALLON PEN" it's that the worlds fishing industry is decimating the worlds fish populations at a much faster rate than it can reproduce. About three quarters of monitored marine stocks are now fully exploited, overexploited, or even depleted. At the continued rate it won't be long until our oceans will be a the point of no return.
