One platform can service 9 large net pens (20m x 50m) and raise ~ 9 million fish to 1 lb in a year costing <$1/fish. The total allowable harvest for both commercial and recreational fishermen for red snapper in the Gulf of Mexico is ~ 9 million pounds a year. The bottleneck facing marine stock enhancement, however, is the inability of U.S. institutions to produce large quantities of fingerlings of marine fish. Most of the research efforts into fish farming and stock enhancement in the U.S. have been directed towards fresh water species. Elsewhere around the globe, most notably Japan, there have been numerous successful efforts to spawn and raise marine species for stock enhancement.
