Research Advances on Nutrient Requirements of Micropterus Salmoides
摘要
Abstract
The nutrient requirements ofMicropterus salmoides were reviewed in this paper. Dietary protein requirement of largemouth bass is no less than 37% ,and the optimal level is 40%.7%～16% lipid can be included in the diet,but the optimal level is 7%- 10%.Carbohydrate level should be no more than 20%. The reported values for dietary lysine and methionine were 4.9,1.9 g/100 g protein. The deduced requirement values of other essential amino acids by using the ideal protein concept were arginine 6.31 g, histidinel.31 g,isoleucine 2.59 g ,leucine 5.02 g, methionine＋cysteine 2.10 g, phenylalanine＋tyrosine 4.38 g,threonine 2.74 g,tryptophan 0.56 g,and valine 2.90 g in 100 g protein,which can meet the dietary requirements of Micropterus salmoides at different growth stages. The requirements of essential fatty acids,vitamins,and minerals have not been determined yet. According the reported values of the essential fatty acids requirements from other freshwater fish species ,0.5%-1.0% either linoleic or lenolenic acids should be incorporated in the diet of Micropterus salmoides. For cost-effective feed development for Micropterus salmoides ,besides the studies on the essen-tial fatty acids, vitamins and minerals requirements, more research should be conducted on the commonly used protein, lipid and carbohydrate sources.关键词
