南方鲇幼鱼和成鱼血液指标的比较

测定了南方鲇(Silurus meridionalis)幼鱼和成鱼部分血液生理及生化指标,结果表明,南方鲇幼鱼和成鱼血液中红细胞数量(RBC)、白细胞数量(WBC)、白细胞分类计数(DLC)、血红蛋白(Hb)、血糖(GLU)、总蛋白(TP)、胆固醇(CHOL)及甘油三酯(TG)二者差异不显著,在对幼鱼与成鱼做血液诊断时这些指标可以用同一个标准。成鱼血液中谷草转氨酶(GOT)活性显著高于幼鱼,而幼鱼血液中谷丙转氨酶(GPT)、碱性磷酸酶(AKP)活性显著高于成鱼,幼鱼血液中氯离子(Cl-)浓度极显著高于成鱼,在对南方鲇幼鱼和成鱼做血液学诊断时需要设定不同标准。

Comparative Study on Hematological Indices in Larval and Adult Southern Catfish

The present study investigated hematological and biochemical indices in larval and adult Southern Catfish(Silurus meridionalis).The results showed that erythrocyte number,leukocyte category and number as well as the concentration of hemoglobin in larval and adult Southern Catfish were not significantly different,but the number of erythroid precursors of the adult was higher than that of larvae.The concentrations of plasma glucose,total protein,albumin,globulin,cholesterol,triglyceride in larval and adult Southern Catfish were slightly different.However,the activity of alanine aminotransferase and alkaline phosphatase and the Cl~-concentration in larval blood were significantly higher than those of the adult,while the activity of aspartate aminotransferase was significantly lower in the larval than that in the adult.
