克氏原螯虾(Cambarus clarkii)是一种分布范围较广的淡水虾类,因其壳稍厚、头胸甲较大、螯足粗壮,含肉率较日常食用的其它虾类为低。本文对克氏原螯虾的含肉率和营养成份作了分析,测定结果表明:总含肉率虽不及日本沼虾,但最高也有24.5%;含肉率的高低与个体大小、性成熟程度、以及季节生长等特点有关;肌肉中的氨基酸含量丰富,不亚于食用鳊鱼。对此种虾类的自然资源利用应当予以重视。 Cambarus clarkii is a widely distributed freshwater prawn with a slightly thicker shell with a larger breastplate and a thicker chevrons with a lower meat content than other prawns that are consumed daily. The results showed that although the total meat content was not as high as that of Japanese marsh shrimp, the highest content was 24.5%; the content of meat content was different from the individual size, sexual maturity, As well as the characteristics of seasonal growth and other related; rich in amino acids in muscle, no less than eating anchovy. The use of natural resources of such shrimp should be given priority.
