水解鱼蛋白的营养特征及其在水产动物营养饲料中的研究进展

鱼粉短缺是当今水产饲料行业中亟待解决的难题,而水产品加工副产品占水产品的总重量超过60%,因此,充分利用水产品加工副产品,提高其营养价值,是解决鱼粉短缺的重要途径。水解鱼蛋白是水解水产品加工副产品而得到的富含游离氨基酸和不同肽链长度的蛋白寡肽,目前,越来越多的研究证明,其对水产养殖动物的生长性能具有重要的促进作用。本文从水解鱼蛋白的制备、营养特性及水产饲料中的研究和应用方面展开综述,系统论述近年来水解鱼蛋白在水产动物营养相关领域的研究成果,并提出在水产饲料中的进一步研究方向,以期为水解鱼蛋白在水产动物营养学研究及其在水产饲料中的应用提供参考。

Nutritional characteristics of fish protein hydrolysate and related research progress in aquaculture nutrition

The shortage of fishmeal is an urgent problem to be solved in the research of aquaculture nutrition. Given that fish by-product accounts for more than 60% of processed fish biomass, more efficient use of marine protein from fish by-products and improving their nutritional value are important ways to alleviate fish meal shortage at present. Fish protein hydrolysate, which mainly contains a mixture of small peptides and free amino acids, is produced by hydrolyzing fish by-products. More and more studies have proved that fish protein hydrolysate has a beneficial effect on the growth performance of aquatic animals. This paper reviews the preparation of fish protein hydrolysate, its nutritional characteristics and study on aquaculture nutrition. This study systematically discusses the research results of fish protein hydrolysate in the field of aquaculture nutrition in recent years, and proposes further research directions in aquafeed, in order to provide reference for the study of fish protein hydrolysate in aquaculture nutrition and aquafeed application.
