Abstract
Four 38 m3 (1341 ft3) circular pools were stocked with fingerling hybrid female striped bass x male white bass at 9 and 18 fish/m3 (0.25 and 0.5 fish / ft3). The average weight of the fish was 53 g (0.117 lb) on 9 April 1981. Survival to harvest (21 November 1981) in the high density pools averaged 74% and the mean standing crop was 3.34 kg/m3 (260 lb/ft3). In one remaining low density replicate (fish in one tank were lost due to a power failure), survival at harvest was 88% and the standing crop was 3.02 kg/m3 (235 lb/ft3). No significant differences were detected in the growth in length or weight of the hybrids between densities. Analysis of variance indicated that growth was adversely affected by chronically low temperature and oxygen conditions in the pools.
