光色对豹纹鳃棘鲈幼鱼摄食、生长和存活的影响
Effect of light color on feeding, growth, and survival of Plec-tropomus leopardus juveniles
摘要
Abstract
To investigate the effect of light color on feeding, growth, and survival of Plectropomus Leopardus, we designed a series of aquaculture water-tank experiments for a small modular circulating-water aquaculture system us-ing five different light colors (red, yellow, green, white, and black) on juvenile fish [initial length (21.2 cm±1.22 cm);initial weight (112.46 g±2.632 g)]. The system was operated on a four-month circulating-water cycle. Our key re-sults are summarized as follows:High-strength feeding intensity ((0.995%±0.052%)·d), a high feed-conversion rate (85.767%±0.446%), and the lowest bait coefficient (1.166±0.034) for the juveniles were observed under green light conditions; however, there were no significant differences in feeding of the juveniles under different light colors (P>0.05); A high growth rate was observed under green and red light conditions, and the growth in this case was significantly different from that in the other three groups (P<0.05); There were no significant differences in the condition factor (CF) for different light-treatment groups (P>0.05); The lowest survival rate (50%) was observed under white light;the survival rates in the other four groups were all higher than 80%. The maximum survival rate (88.33%) was observed under green light. In conclusion, juvenile fish may survive, grow, and feed better under green light in indoor circulating-water aquaculture systems.关键词
