Abstract

Large changes are taking place in yielddetermining traits of commercially exploited fish including traits such as sizeatage and ageatmaturation The cause of these phenotypic changes is often not understood and genetic change arising from the selective effects of fishing may be a contributory factor Selection generated by fishing gear is strong in heavily exploited fish stocks and the spatial location of fishing can also cause strong selection The success of selective breeding in aquaculture indicates that significant amounts of genetic variation for productionrelated traits exist in fish populations Fisheries managers should be alert to the evolutionary change caused by fishing because such changes are likely to be hard to reverse and if properly controlled could bring about an evolutionary gain in yield
