After the wild striped bass stocks nearly collapsed, the aquaculture industry responded by engineering this hybrid. The new species was established in 1967 by crossing the anadromous wild striper (Morone saxatilus) with white bass (M. chrysops), a fish that lives in both estuarine and fresh water. The result combines the attractive appearance and edibility of the wild striped bass with the hardier, faster-growing characteristic of the white bass. The hybrid also offers a greater yield than its wild parents. Farmed striped bass reach 5 pounds but are usually marketed at 1 to 3 pounds. The fish are grown in ponds, tanks and cages at more than 50 farms in the United States, but farms in the western region account for half the national production. Hybrid striped bass can be harvested, chilled, graded, sorted and shipped to market within 24 hours, ensuring freshness and quality. High production costs relegate hybrid striped bass to a niche market.
