中华绒螯蟹分子育种群体的区域养殖试验
Regional culture trial of molecular breeding population of Chinese mitten crab
摘要
Abstract
In order to study the production performance of the molecular breeding population of Eriocheir sinensis in different breeding areas,and to provide a basis for subsequent breeding and promotion of varieties,the diffe-rences of growth performance and nutritional quality of adult crabs in four breeding bases of Shanghai Songjiang Sanmao Town,Baoshan Luojing Town,Chongming Hengsha Township and Chongming Sanxing Town were com-pared.The results showed as follows:①There were significant differences in body mass,fattenity,hepatopancreas index and gonadal index of cultured crabs in different regions(P<0.05).The growth variation was greater when the breeding environment was poor.②The overall heritability of body mass and shell length of the selected popula-tion was 0.358 and 0.357,respectively,which belonged to the medium heritability.③The contents of total choles-terol in hemolymph of adult crabs from different bases were different to some extent,and the activities of lipase and amylase in hepatopancreas were significantly different among different bases(P<0.05).④Crude protein and crude fat in muscle and hepatopancreas were significantly different among different sites(P<0.05).Essential and non-essential amino acids in muscle were not significantly different among the four sites(P>0.05),but essential and non-essential amino acids in hepatopancreas were significantly different among the four sites(P<0.05).⑤The contents of saturated fatty acids,monounsaturated fatty acids and polyunsaturated fatty acids in muscle and hepato-pancreas tissues of crabs from different bases were significantly different(P<0.05).The results showed that the molecular breeding population of Chinese mitten crab had good production performance in different breeding areas,which could be used for further breeding and popularization of breeding.关键词
