Fast-growing farm-raised salmon and trout that are sterile can now be produced using a method developed by USDA Agricultural Research Service (ARS) scientists. Blocking reproduction can enhance growth, and is important for fish being reared in situations where reproduction is undesirable.
Bigger fish for consumers and sterile fish for producers and anglers are the goals of ARS scientists who are working with the aquaculture industry on genetic methods to more efficiently produce fish that grow faster on less feed and can't reproduce in the wild.
According to the USDA Agricultural Research Service, scientists have made improvements studies are expanding to include to Atlantic salmon, brook trout and brown trout. Experiments involving these species could determine whether sterile fish offer improved production traits such as growth to market size, stress tolerance, and disease resistance.
