中华绒螯蟹池塘套养与温室养殖的中华鳖雄体生物学指数和营养成分比较
Comparison of biological indices and nutritional composition of male Chinese soft-shelled turtle, Trionyx sinensis, reared in a greenhouse and eco-pond for Chinese mitten crab, Eriocheir sinensis
摘要
Abstract
Five male greenhouse reared Chinese soft-shelled turtles (Trionyx sinensis) and five male T.sinensis from the eco-pond for Chinese mitten crabs (Eriocheir sinensis) (defined as greenhouse reared [GR] and eco-pond reared [ER],respectively) were dissected to collect muscle,soft apron,and liver,and proximate composition and amino acid and fatty acid contents in edible tissues were determined to investigate differences in biological indices and nutrient composition of edible tissues.The results showed that the soft apron index and hepatosomatie index of GR were significantly higher than those of ER (P＜0.05).Muscle crude ash and soft apron moisture contents were significant higher in ER than those in GR (P＜0.01),while higher soft apron protein content was detected for GR,but no differences in any other proximate composition factors were detected between T.sinensis in the two environments.The contents of most amino acids,total essential amino acids (∑ EAA),and total amino acids (TAA)in muscle and the soft apron of GR were significantly higher than those of ER (P＜0.05),but higher cysteine content and ∑ EAA/TAA ratio were found in ER than those in GR.The muscle and soft apron essential amino acid scores (EAAS) were similar in ER and GR,but higher mean EAAS was observed in ER than that in GR.(4) C18:1n9 and C18:1n7 fatty acid and total muscle monounsaturated fatty acid contents were significantly higher in GR than those in ER,but C22:6n3,total polyunsaturated fatty acid (∑ PUFA),∑ n-3PUFA,total highly unsaturated fatty acid,and the n-3/n-6 ratio were significant higher in ER than those in GR (P＜0.05).Soft apron C17:0 and C20:2n6 contents were significantly higher in GR than those in ER (P＜0.05),but no differences were detected in any of the other fatty acids.These results indicate the high nutritional value of male T.sinensis reared in the two environments.关键词
