Abstract: In order to choose a reasonable way of farming, improve the nutritional value and simple identification of Trionyx sinensis. Wild, bionics and hothouse Trionyx sinensis were used as experimental material, analyse the physical characteristics and nutritive components of three kind of Trionyx sinensis between different cultivation patterns. The results indicated that the skirt weight of wild turtle and bionics turtle were higher than hothouse turtle(P<0.05).The content of crude protein in muscle of wild turtle was higher than that of the other turtle 0.78%,6.37%, respectively(P>0.05).The content of crude protein, crude ash and moisture in livers of wild turtle were significantly higher than bionics and hothouse turtle(P<0.05),but the content of crude fat was lower than others. There were also differences in composition of fatty acids. The wild turtle had higher PUFA content in muscle compared with that in bionics and hothouse turtle(P<0.05). The EPA+DHA content in muscle were significant difference in three turtles, hothouse turtle> bionics turtle> wild turtle(P<0.05).
