| Abstract: | To observe the variation of body composition of Squaliobarbus curriculus,36 specimens with body length of 68～175 mm and body weight of 4.78～104.88 g were collected from the lower reaches of Hanjiang river in June,2010,and divided into 5 groups according to the body length(L).Chemical compositions and energy density were measured.The results showed that the contents of water(WAT),protein(PRO),lipid(FAT) and ash(represented by percentages of them in fresh body weight of fish,respectively) ranged 72.79%～75.54%,12.99%～17.06%,8.18%～12.88% and 2.35%～3.38% respectively.The energy density(E) ranged 6.29～9.11 kJ/g.With the increase of L,PRO,FAT and E,WAT decreased.PRO,FAT and E were all positively correlated with L,while WAT was negatively correlated with L(P<0.05).The contents of PRO,FAT and E were all negatively correlated with the content of WAT(P<0.05).The results suggested that the contents of PRO,FAT and E of S.curriculus could be estimated by the content of water or body size.The high content of lipid with the increasing body size in this species may be resulted from its acclimation to the slow flow water environment and abundant food resources. |
