A series of trials were conducted with Pacific white shrimp Litopenaeus vannamei, to evaluate the efficiency of two salmon meals as compared to anchovy meal. The basal diet contained 200 g/kg anchovy meal, which was systematically replaced (0%, 50%, 75% and 100%) with salmon meal on an isonitrogenous basis. Another two diets were formulated with a hydrolysed salmon meal to replace 50% and 100% anchovy meal. Each diet was randomly fed to four replicate groups of 25 and 30 shrimp per tank in clear (indoor) and green (outdoor) water trials, respectively. The results showed that growth performance and feed conversion ratio were not statistically different when salmon meal replaced anchovy meal in both trials. However, when hydrolysed salmon meal was used to replace 100% of the anchovy meal, growth performance of the shrimp significantly decreased. The four kinds of fish meal (anchovy, salmon by‐product meals and menhaden) were evaluated in an ingredient digestibility trial using the 70:30 replacement technique. In general, dry matter, energy, protein and individual amino acids digestibility of salmon meal were significantly higher than those of menhaden and anchovy meal. Results of this study demonstrated that salmon meals are a good protein sources which can replace anchovy meal.

在太平洋白虾（凡纳滨对虾）的实际饮食中使用鲑鱼副产品粉代替鳀鱼粉

对南美白对虾进行了一系列试验，以评估两种鲑鱼粉与凤尾鱼粉相比的效率。基础日粮包含 200 g/kg 鳀鱼粉，在等氮基础上用鲑鱼粉系统地替代（0%、50%、75% 和 100%）。另外两种饮食是用水解鲑鱼粉配制的，以代替 50% 和 100% 的鳀鱼粉。在清水（室内）和绿色（室外）水试验中，每种饲料随机喂给四个重复组，每罐 25 只和 30 只虾。结果表明，在两项试验中，当鲑鱼粉代替鳀鱼粉时，生长性能和饲料转化率没有统计学差异。然而，当用水解鲑鱼粉代替 100% 的鳀鱼粉时，虾的生长性能显着下降。在成分消化率试验中使用 70:30 替代技术评估了四种鱼粉（凤尾鱼、鲑鱼副产品粉和鲱鱼）。总的来说，鲑鱼粉的干物质、能量、蛋白质和单个氨基酸的消化率显着高于鲱鱼和鳀鱼粉。这项研究的结果表明，鲑鱼粉是一种很好的蛋白质来源，可以替代鳀鱼粉。
