Effects of Starvation and Refeeding on the Physiological and Biochemical Indices of Blood of Hucho tajmen Juveniles

Hucho tajmen juveniles were disposed with the starvation for 7 d,14 d,21 d and 28 d,then resumed to refeed for 49 d,42 d,35 d and 28 d respectively.The effects of starvation and refeeding on the physiological and biochemical indices of the blood of H.tajmen juveniles were studied in this experiment.Results were revealed as following:The numbers of the red cell,white cell and the hemoglobin increased obviously(P0.05)after starvation for 14 d and then decreased after starvation for 21 d.The serum glucose levels decreased sharply(P0.05)after starvation for 7 d and then kept stably.The concentration of total protein,albumin and globin decreased significantly after starvation for 21 d,28 d and 7 d respectively.The serum triglyceride and the total cholesterol decreased sharply(P0.05)after starvation for 7 d and 14 d.The ALT and AST decreased significantly(P0.05)after starvation for 14 d.The AKP decreased significantly(P0.05)after starvation for 7 d.The concentrations of Na+ and Cl-decreased significantly(P0.05)after starvation for 7 d,then increased significantly(P0.05)again after starvation for 14 d.The concentration of Ca2+ increased sharply(P0.05)after starvation for 14 d,then decreased significantly(P0.05)after starvation for 28 d.The concentration of K+ increased after starvation,but there were no differences among the groups.After re-feeding,the blood indices all recovered with different dedree.
