摘　　要：通过测量口虾蛄与黑斑口虾蛄的长度指标与质量指标,来研究和比较两者生长模式;通过测定两者肌肉的生化组成及其含量,评价与比较其营养价值,探讨生化成分与其生长、繁殖的关系。结果表明:二种虾蛄的长度指标之间呈显著的线性关系,质量指标之间也呈显著直线关系,质量指标与长度指标呈幂函数关系;在生长过程中,二种虾蛄的体型基本稳定。二种虾蛄肌肉的水份、粗脂肪与灰分含量没有明显差异,但粗蛋白含量有显著差异(P<0.05);在测定的月份中,脂肪含量波动很少,水份、灰分与蛋白质含量呈上升趋势。二种虾蛄肌肉中所含的氨基酸绝对含量差异极显著(P<0.01),且黑斑口虾蛄的氨基酸、必需氨基酸(EAA)和呈味氨基酸(Asp+Glu+Gly)含量均高于口虾蛄,但EAA/TAA二种虾蛄没有明显差异。口虾蛄的不饱和脂肪酸含量高于黑斑口虾蛄。In this paper we study and compare growth pattern of Oratosquilla oratoria and Oratosquilla kempi, evaluate and compare nutritive value, and investigate relationship between biochemical composition and growth, reproduction by measuring body length and weight ,biochemical composition and content, respectively. Results show that both the body length relation and the body weight relation between two species can be expressed in the significant linear correlation, body weight bears power function relation to length, and during the growing period two body shapes are mainly stable. The contents of water, lipid and ash in muscles are not of significant difference, except for that of crude protein (P<0.05).During the test months lipid contents have little fluctuation but contents of water, ash and protein are all on the rise. The differences in amino acids(AA) and fatty acid composions in muscles of Oratosquilla oratoria and Oratosquilla kempi were found.The values of AA,EAA and Asp+Glu+Gly of the latter are higher(P<0.01) than those of the former, and unsaturated fatty acids of the former are higher than those of the latter.
