The animal scientist at Purdue University, Bill Muir, and biologist Rick Howard conducted a study to examine the risks and benefits from biotechnology, for example, genetically modified fish. They put Japanese fishes called medaka that had been genetically modified with a growth hormone from Atlantic Salmon into a tank with unmodified fish to see what happens. They found that this experiment could potentially devastate the native populations of fish possibly to extinction. When the unmodified fish look for a mate, they look for the largest fish rather than the fittest. Therefore, they would pick the transgenic fish, who's offspring have a chance of not surviving because of the genetic change. However, they say that this is all a part of testing biotechnology and are going to try to test the transgenic fish in a larger setting and with larger fish next time.
