Interpretive Summary: In order to provide a year-round supply of sunshine bass fingerlings it is necessary to develop cost-effective methods to culture the fingerlings in tanks. Presently, nearly 100 per cent of them come from pond culture facilities. Use of methods developed at HKD-SNARC has increased survival of pond raised fingerlings from 10% to 35%. An HKD-SNARC scientist was the first to report tank culture of sunshine bass by using fresh-water rotifers. He also demonstrated that live feed for tank cultured fish could be obtained by harvesting zooplankton from ponds. Recently, by using high feeding levels of rotifers and brine shrimp nauplii with a range of fry stocking levels the HKD-SNARC scientist obtained the largest fingerlings (at 27 days after hatching) yet produced in tanks. Additional research to determine optimum conditions in tanks and methods of fry handling will be needed to obtain cost-effective fingerling production in tanks.
