Hybrid Striped Bass
Hybrid striped bass farmed in the United States are a "Best Choice" when produced in ponds and recirculating aquaculture systems because of relatively light environmental impacts.
Hybrid striped bass is a popular food and sport fish throughout the western and southern regions of the United States. While the majority of production occurs in earthen ponds, small volumes of fish are also produced in recirculating aquaculture systems. Hybrid striped bass is available year-round and common market names include bass, wiper, rockfish, sunshine bass, and palmetto bass. Hybrid striped bass is known as suzuki when prepared for sushi. They may be sold live in Asian markets.
Hybrid striped bass are predominately a cross between female freshwater white bass and male anadromous striped bass.
Both recirculating systems and low-water-exchange ponds have a low discharge of effluent into the environment, and have low concerns with respect to effluent. As ponds are drained infrequently, there is low concern over disease transfer to wild stocks of fish. The level of fishmeal and oil used in feeds is a moderate concern. Demonstrated low numbers of escapes coupled with intentional stocking for sport fishing means that there is low concern regarding escapes.
Additionally, all hybrid striped bass grown on farms are produced utilizing broodstock as opposed to wild capture; therefore these aquaculture practices do not deplete wild stocks.
Overall, hybrid striped bass farmed in ponds in the United States is a "Best Choice."
