研究鱼类营养的目的,在于了解鱼类健康成长所需的饲料量及其营养组成。由于鱼类生活在水中,因此,鱼类营养学的研究比起哺乳动物要晚且困难得多。现在,作为研究对象的主要有虹鳟鱼、大鳞大哈鱼、鲤鱼、鳗鱼、真鲷、美洲鲶鱼、(鱼师)鱼、鲇鱼等。此外,对鲍、对虾所需营养的研究也已取得了进展。 The purpose of studying fish nutrition is to understand the amount of feed required for the healthy growth of fish and its nutritional composition. Since fish live in water, the study of fish nutrition is much later and more difficult than that of mammals. Nowadays, rainbow trout, salmon, carp, eel, red sea bream, American catfish, (croaker) fish and catfish are the main research subjects. In addition, the research on the nutrition required for abalone and shrimp has also made progress.
