为准确测定出养殖鲤饵料中赖氨酸的适宜添加量,以色列农业部水产局鱼类精养研究站在池塘和网箱中对3种规格的鲤进行了试验.试验鱼平均体重分别为80g、125g和560g,养殖水温分别为22℃和26℃,投饵量分别为鱼体重的3%、4%和5%.试验饵料中分别添加赖氨酸0.5%、0.75%、1.0%和1.5%.结果表明饵料中的赖氨酸添加量由0.5%增加至1.7%,明显提高了鱼的生 In order to accurately determine the appropriate amount of lysine in cultured carp bait, the Fisheries Bureau of Israel Fish Research Station of Israel’s Ministry of Agriculture carried out experiments on three kinds of carp in ponds and cages.The average body weight of test fish was 80g , 125g and 560g respectively.The feeding water temperature was 22 ℃ and 26 ℃ respectively, and the feeding amount was 3%, 4% and 5% of the body weight respectively.The lysine 0.5%, 0.75%, 1.0% and 1.5% % .The results showed that the amount of lysine in the feed increased from 0.5% to 1.7%, significantly increased the fish’s health
