日本囊对虾两种形态差异体形态性状、生长特性和耐热性比较研究

Abstract

日本囊对虾Marsupenaeusjaponicus(Bate，1888)是我国沿海重要的经济养殖虾类，依据其头胸甲侧部斜纹全延伸与否可分为两种不同形态的差异体，二者地理分布不同并具较大遗传分化。以两类群体为材料，开展相关育种基础研究，具重要现实意义。本文首先研究比较了两种形态差异体群体生长特性，并通过多元分析确定影响其体质量的主要形态性状；其次，比较了二者的热耐受性，并初步探讨其耐高温机理；同时，克隆了日本囊对虾的HSP60基因并分析其热激时空表达，以期为更好开展日本囊对虾养殖生产和相关遗传育种提供实验依据和理论参考。主要研究结果如下： 1.室内养殖环境下两种形态差异体群体生长特性研究 ...

Kuruma shrimp (Marsupenaeus japonicus Bate, 1888) is one of the most important species of shrimp culture along the coast of China. Previous study recognized two morphologically similar of M. japonicus and which were characterized by diagnostic color banding patterns on the carapace, moreover, these two varieties dad different geographical distribution and exsisted high genetic differentiation. In...
