摘要
随着水产养殖业的发展及全球渔业资源的衰退,鱼粉供不应求,价格逐年攀升。因此,寻求替代鱼粉的新型非粮蛋白源,降低饲料中的鱼粉含量,已成为促进水产养殖业可持续发展的重要途径。小球藻(Chlorella vulgaris)是一种球形单细胞绿藻,是最早实现商业化生产的微藻,其含有丰富的蛋白质、氨基酸、维生素和矿物质等。小球藻粉作为一种优质的新型非粮单细胞藻类蛋白源,在水产饲料中得到广泛应用。文章在查阅国内外相关文献报道基础上,概述了小球藻粉的营养特性及作为非粮新型蛋白源对水产养殖动物生长性能、消化代谢、免疫功能等方面的影响,旨在为合理开发利用新型非粮蛋白源,优化饲料配方,节约鱼粉蛋白,以期为降低饲料成本提供理论依据。
With the development of aquaculture and the decline of global fishery resources,fishmeal supply is falling short of demand,leading to a continuous increase in prices.Therefore,seeking a new nongrain pro-tein source as an alternative to fishmeal and reducing the content of fishmeal in feed has become an impor-tant way to promote the sustainable development of aquaculture.Chlorella vulgaris is a spherical unicellular green alga,one of the earliest microalgae to be commercially produced,which is rich in proteins,amino acids,vitamins,and minerals.As a high-quality new nongrain monocystis protein source,chlorella powder is widely used in aquatic feed.Based on a review of relevant domestic and international literatures,this article outlines the nutritional characteristics of chlorella powder and its effects on the growth performance,digestion and metabolism,immune function of aquatic animals as a nongrain new protein source.The aim is to provide a theoretical basis for the rational devel-opment and utilization of new nongrain protein sources,optimization of feed formulation,saving fishmeal protein,and reducing feed costs.
