湖泊围养鱼类血液学指标的初步研究

本试验测定了185尾在湖泊围养区和池塘内体质健壮的草鱼、青鱼、团头鲂、鲢鱼、鳙鱼的血液,共取得红血球、血红蛋白、血糖、总蛋白、白蛋白、尿素氮、胆固醇、甘油三酯八项指标的1367个数据。经可靠性分析,除血糖指标的相对误差值略高于5％外,其余各项血液指标均值的相对误差,均达到生物调查实验要求。

ON HEMATOLOGY OF THE BLOOD OF FISHES CULTURED IN THE LAKE PEN

In this experiment, the blood of 185 healthy fish including grass carp, black carp, wuchang fish, silver carp and bighead carp were measured, 1367 data including erythrocyte, hemoglobin, blood sugar, total protein, albumin, urea nitrogen, cholestrol and triglyceride were obtained. Through the reliable analysis, the average error rate of all the data was less than that of the biological tests in investigutions except that the blood sugar has a relative error above 5%. The results of experiments have shown as follows:1. The blood indexes of fish are variable with species Except for the erythrocyte, the value of other seven indexes is in the following order: carnivorous fish herbivorous and omnivorous fishesfiltering feeders.2. The blood indexes of fish are affected by the environmental conditions The values of blood sugar, total protein, albumin, hemoglobin and urea nitrogen of wuchang fish and grass carp reared in running water are much higher than those of the pond fish.3. The blood indexes also related to the nutrtive availability. Fish of higher nutritive value can be cultured by taking natural organisms as the main food source and the commercial food as supplementary.
