Interpretive Summary:

Technical Abstract: Sunshine bass are an important food fish raised in US aquaculture. Spawning of these hybrid striped bass is done by manual fertilization of female white bass eggs with male striped bass sperm. The industry grows these fish to approximately 1.5 to 2 lbs over approximately 1.5 to 2 years, during which time the females can become fertile and produce eggs. This is a major problem in the industry, as the majority of producers sell these fish whole and there is a considerable loss in weight (i.e., dollars) due to expulsion of eggs caused by handling stress; eggs prematurely released can also lead to considerable water quality issues. Therefore, the industry needs a way to produce sterile fish.
