Fisheries biologist David O. Conover is investigating the claim that perhaps the "big fish" simply don't exist anymore. According to his work, many fish are evolving smaller body sizes.
He is studying the impact of fishing practises on our lakes, streams, and oceans. 'Humans may be causing major evolutionary changes in the fish species that are most important to us economically.'
