초록
The aim of this study was to investigate the effects of stocking density and water temperature in the rearing of the longtooth grouper Epinephelus bruneus . Juvenile fish [mean body weight (BW)=6.9±1.1 g] were raised for 6 weeks, in four density groups of 0.25, 0.5, 0.75, and 1 individuals/L. There were no significant differences in weight gain (WG) or specific growth rate (SGR) among the density groups; however, both WG and SGR tended to be higher in the low density group. After 6 weeks of rearing in temperature-controlled water (23.6±0.8°C) and ambient temperature water (19.6±1.8°C), there were no significant differences in WG or SGR values, but both tended to be higher in the temperature controlled water. The feed efficiency (FE) and daily feed intake (DFI) and WG values were also higher in the temperature-controlled water than in the ambient temperature water. WG values were lower at lower water temperatures. The same pattern was observed for SGR, FE, and FI, all of which exhibited lower values at lower temperatures. In particular, WG, SGR, and FE values all tended to decrease at the 16°C water temperature. The effects of water temperature on 1-year fish (mean BW = 387.6±30.2 g) and 3-year fish (mean BW = 1,338.3±73.8 g) were similar to those of the juvenile fish (0-year fish).
Abstract
The aim of this study was to investigate the effects of stocking density and water temperature in the rearing of the longtooth grouper Epinephelus bruneus . Juvenile fish [mean body weight (BW)=6.9±1.1 g] were raised for 6 weeks, in four density groups of 0.25, 0.5, 0.75, and 1 individuals/L. There were no significant differences in weight gain (WG) or specific growth rate (SGR) among the density groups; however, both WG and SGR tended to be higher in the low density group. After 6 weeks of rearing in temperature-controlled water (23.6±0.8°C) and ambient temperature water (19.6±1.8°C), there were no significant differences in WG or SGR values, but both tended to be higher in the temperature controlled water. The feed efficiency (FE) and daily feed intake (DFI) and WG values were also higher in the temperature-controlled water than in the ambient temperature water. WG values were lower at lower water temperatures. The same pattern was observed for SGR, FE, and FI, all of which exhibited lower values at lower temperatures. In particular, WG, SGR, and FE values all tended to decrease at the 16°C water temperature. The effects of water temperature on 1-year fish (mean BW = 387.6±30.2 g) and 3-year fish (mean BW = 1,338.3±73.8 g) were similar to those of the juvenile fish (0-year fish).
