2种饵料模式对河蟹肌肉、肝胰腺和性腺营养组成及含量的影响
Effects of two feeding patterns on nutrient composition and content of muscle,hepatopancreas and gonads of Chinese mitten crab(Eriocheir sinensis)
摘要
Abstract
In order to study the effects of different feeding patterns on the nutritional quality of the edible parts of Chi-nese mitten crab(Eriocheir sinensis),a four-month culture experiment was conducted.Two groups were set up as group T1(compound feed),and group T2(compound feed+frozen fresh fish),with three replicates in each group,15 male and 15 female crabs in each replicate.The results showed that there was no significant difference in muscle,hepatopancreas and gonadal nutrient levels in male crabs between group T1 and T2,while in female crabs,muscle moisture and crude protein contents in group T2 were significantly higher than those in group T1,and crude lipid content was significantly lower than that in group T1.Meanwhile,the moisture content of the hepatopancreas in female crabs was lowest in group T2(P<0.05),while the crude lipid content was highest in group T2(P<0.05).In the gonads of female crabs,there was no significant difference in nutrient composition between groups T1 and T2;in the muscles of male crabs,the glu-tamic acid content in group T1 was significantly higher than that in group T2),while the contents of serine,threonine,valine,methionine,cysteine,and isoleucine were all significantly lower in group T1 than those in group T2.In the go-nads of male crabs,the contents of methionine,phenylalanine,and lysine were significantly higher in group T1 than in group T2,while the content of aspartic acid was significantly lower in group T1 than that in group T2.In the hepatopan-creas of male crabs,the contents of aspartic acid and methionine in group T1 was significantly higher than that in group T2,while the content of cysteine was significantly lower than that in group T2.In the muscle of female crabs,the con-tent of serine and cysteine in group T1 was also significantly lower than those in group T2.In the gonad of female crabs,the content of methionine,cysteine and isoleucine in group T1 was significantly higher than those in group T2.In the hepatopancreas of female crabs,the content of methionine in group T1 was significantly lower than that in group T2,while the content of cysteine was significantly higher than that in group T2.There were no significant differences in the other amino acid contents;however,the total amount of polyunsaturated fatty acids in the tissues of male crabs and the gonad and hepatopancreas of female crabs in group T1 was significantly higher than that in group T2.In conclusion,the whole diet is more conducive to the accumulation of polyunsaturated fatty acids,and can significantly increase the crude lipid content in muscle and hepatopancreas of female crabs,but the crude protein content in muscle of female crabs is low.关键词
