| Abstract: | Pacific white leg shrimp Litopenaeus vannameiinitial body weight(9.84±0.14) g] were fed five experimental diets containing lipid levels of 4.64%,6.56%,8.47%,10.39% and 12.31% for 60 days at water temperature ranging from 23.4 ℃ to 27.0 ℃ to evaluate effects of dietary lipid levels on growth and metabolism in the shrimp.The results showed that the maximal weight gain,the survival rate and the minimal food conversion ratio were observed in the shrimp fed the diet containing lipid of 8.47%.There were significant positive relationships between C18:3n-3 level in hepatopancreas of male shrimp and C20:4n-6,C20:5n-3,and C22:5n-3 levels in muscle of male shrimp and the dietary lipid levels(P<0.05).There were significant effects of dietary lipid levels on the lipid contents in the hepatopancreas and muscles,and changes in hepatopancreas cells were found in the shrimp fed the diets containing different lipid levels. |
