Writing in High Country News, Jan. 16, 2012, Stephanie Paige Ogburn says that there are upsides and downsides to the genetically engineered farm-raised salmon, one upside is that they are neutered like triploids, so they cannot reproduce in the wild and genetically harm native wild fish populations. Another is that they grow faster than nonneutered salmon being raised in netpens and that they escape by the millions and find their way into nearby streams to compete with (and cross-breed with) native runs of salmon. (The geneticaly-modified salmon designed by AquaAdvantage may soon be approved by the U.S. Food and Drug Administration.)
