Production of striped bass, (Morone saxatilis), fingerlings for stocking into Mississippi coastal streams in support of Mississippi's striped bass restoration program has been a continuing goal of the Anadromous Fish Section of the Gulf Coast Research Laboratory since 1969. Hydrological conditions and land use restrictions necessitated the development of a closed culture system for production of striped bass fingerlings. The closed culture system was composed of two earthern ponds plumbed to twenty‐five 3,900 liter circular tanks used for rearing. Pond No. 1 was stocked with water hyacinths (Eichhornia crassipes) and used as a biological filter and Pond No. 2 served as a water reservoir for the 25 raceways. Eight hundred and sixty‐nine thousand, 24‐hours old, striped bass sac‐fry were stocked into the circular raceways at the rate of 8.9 fry per liter and 6,424 fish were harvested for a survival rate of 0.73%. Rearing fry to fingerlings took a mean of 60 days (55–63 days). At harvest the fish ranged in total length from 28 to 72 mm and averaged 45.1 mm with an average coefficient of condition of 1.02.
