Stopping the great escape

When farmed fish escape into the wild, they do all sorts of damage to native populations, such as narrowing the gene pool through inter-breeding and spreading diseases. A new study led by Melbourne Uni marine biologist Tim Dempster shows that trying to recapture escapees around marine fish farms is a bad solution that can do much damage with little good. Instead, the study suggests a radical change in focus to reduce the impacts of escapees in the wild.
