I'm not so sure of this. In fact I'm quite convinced otherwise. I can cite plenty of examples, dozens in fact, where the introduced "domestic" animals did quite well. It takes more than spending a bit of time in an aquarium to dull the natural accuities of a most species.
In fact, it's aquarium fish dumped into non-native ecosystems that cause so much trouble in certain areas.

Ditto. I could see this potentially happening with some of the "tamer" fish, like an angel or trigger that will come to be petted by its owner; if released it might be a bit too unafraid of humans.
But sharks, moray eels and the like? These are very dumb, very wild, very programmed instinctual predators. I doubt they'd skip a beat adapting to the wild.
Im not so concerned about the fact that she wouldn't be able to hunt and find food. Im feeding her catfish now, but ive fed her all kinds of stuff. Anytime anything hits the water she goes nuts, thrashing and the like. She's awesome and very aware of food. I keep her water very clean my concern would be that she would introduce something not native. Some might say its only one shark, but I think we all know how a little adds to be alot. I know that captive species are reintroduced into the wild, but i am not completely aware of their process of doing such. They may have a system that makes sure the creatures are not hosting anything. I should probably research that and speak to someone involved in a program that give me more insight before considering the release of an animal back into the wild.

I really do appreciate all of your input.

Matt + Jim - how come other apex predators like tigers, lions, etc aren't released back into the wild from captivity? They have to be kept in reserves.
I know sharks are ancient, primitive predators, but you're talking about an aquarium animal that has never had to dodge larger sharks. If it could hunt, it still couldn't recognize threats quickly enough to survive long. It would get "et" probably.

That's kind of a weird comparison. Mammals are just on a whole different level than fish. Fish have their instincts hard wired from birth. Mammals have to be taught how to hunt, interact socially, avoid predators, etc., by their parents so that behavior is all very plastic. Fish can be taught a few things, but not much, ya know?
Did anyone see the thing on CNN regarding the Boa's in the everglades. They have a problem there because they are being released by pet owners because they get too big, so the drop them in the Everglades.
The concern? The Boa's are killing alligators left and right.
The big climax was a shot of an 18 foot Boa that had died while eating a 6 foot alligator. It was amazing, the alligator was about 2/3s the way inside the Boa... and both were just laying there dead.

I guess you can teach an old fish new tricks.
Or snakes at least.
Good things constrictors have few, if any, predators.
Sharks do prey on other sharks. Oh well, regardless of why, there are a lot of reasons not to release captive animals into the wild.

The Everglades is a mess... completely unsalvageable from an ecological standpoint. The list of exotic species both terrestrial and aquatic that have established themselves there is astounding. You can go fishing there and catch almost any species of Mesoamerican cichlid you can name.

Nothing should be released into an environment that it did not come from, it should be euthanized for the sake of the animal, and the animals it would come into contact with if released. Non-native lionfish released by unethical aquarium keepers have garnered the attention of NOAA, so much in fact that they have conducted a study see...http://www.publicaffairs.noaa.gov/relea ... -r519.html. So if I need to get rid of a fish, I personally put it on ice to euthanize it wheter it is a guppy, or something larger.
Asian carp are knocking on the door of our river systems in the Pittsburgh area where fish such as the paddlefish, rare herrings (goldeye and mooneye) and many other rare native species live. why, because non-thinking people put profit before environmental awareness, now it will cost taxpayers a heckuva lot more money to control Asian carp and its devastating effects on fisheries than was made by the people who wanted to breed the Asian carp. Just venting.
