摘要
设置4组配合饵料蛋白含量分别为48.23%、51.43%、54.09%和56.22%的试验组研究点带石斑鱼人工配合饵料中蛋白质的适宜含量.经过40 d的试验,得出饵料蛋白含量为51.43%的试验组的日均增重量为0.93±0.06 g.d-1、特定生长率为3.72%±0.12%d-1、饵料系数为0.54±0.01,蛋白质效率为363.0%±3.8%,均为最佳.经回归分析,点带石斑鱼人工配合饵料中蛋白质适宜含量为52.1%.
This study setting four groups that protein content in the diets are 48.23%, 51.43%, 54. 09% and 56.22% respectively to investigate the suitable content of protein in artificial diet for Epinephelus malabaricus. After 40 d growth trial, the fish fed the diet containing protein concentration of 51.43% attained the highest weight gain was 0.93 ±0.06 g · d71, specific growth rate was 3.72% ± 0.12% d^-1, feed conversion ratio was 0.54± 0.01 and protein efficiency ratio was 363% ± 3.8% among groups. The regressional analysis reveals the the suitable content of protein in the artificial diet for Epinephelus malabaricus is 52.1%.
