【摘要】 虹鳟鱼，鲤鱼和尼罗罗非鱼是不同品种，不同食性，不同生活水温的淡水养殖经济鱼类．本文测试了它们血液的生理、生化、血液流变学性质突出的２１项指标，计算出了１３项指标，三种鱼合计测试了１６０个样本，共得到５４４０个数据。通过以全血粘度为中心的血液流变学性质的比较研究，运用逐步回归分析，方差分析及差异显著性检验的手段，探讨了每种鱼血液中各因子对全血粘度的影响，比较了三种鱼血液之间各因子的差异。更多还原

【Abstract】 In this paper,the hemorheology values of 46 Salmo grirdneri,56 Cyprinus carpio and 58 Tilapia nilotica were measured. 5440 data were compared by statistical methods of step-by-step regression analysis and new multiple range test. The results show that there are significant differences among the three fishes in blood viscosity at high shear rates,in erythrocyte deformability and aggregation,lower than that of mammal. but not in blood viscosity at low shear rates and in relative viscosity. The blood viscosity of salmo gairdneri is the highest,that of Tilapia nilotica is the lowest. The main facfors that affect blood viscosity sighificantly are haematocrit,plasma viscosity,erythrocyte deformability and erythrocyte aggregation. All hematological differences are interrelated to blood viscosity.更多还原
