Dr. Ian Fleming had something very interesting to say at a (three hour??) presentation at the annual AAAS meeting, according to this EurekAlert!. His research suggests that it may make more sense to farm Atlantic salmon (Salmo salar) than Pacific salmon (Oncorhynchus spp.)...on the Pacific coast. His reasoning is that farmed Pacific salmon could escape and pollute the wild salmon gene pool, while escaped Atlantic salmon would not interbreed with their Pacific counterparts.
