AbstractA 24-day trial was conducted to investigate the individual variations in growth, food intake and activity in 16 juvenile Chinese sturgeon ( Acipenser sinensis Gray) ( initial weight: 8.9- 14.9 g) reared individually at 25 degreesC. Fish were fed to satiation on tubificid worms (mainly Limnodrilus spp.) twice daily. Specific growth rate, food intake, digestibility, growth efficiency, and activity level were determined. Pronounced individual variations (CV = 31.7%) existed in the specific growth rate. Individual growth rate was positively correlated to food intake, growth efficiency and time spent on swimming but was not correlated with digestibility and distance moved. Food intake was positively correlated with distance moved and time spent on swimming. Our results did not support the hypothesis that less active sturgeon had a higher growth efficiency and, hence, higher growth rate.
