摘　　要：为掌握哲罗鱼、白点鲑和美洲红点鲑血液学原始数据,测定了哲罗鱼、白点鲑和美洲红点鲑血液生理、生化指标,以及在5.75/S,9.6/S、11.5/S、23.0/S、46.0/S、115.0/S、230.0/S7个切变率(γ)全血粘度和230/S切变率血浆粘度;将3种鱼在不同切变率下的全血黏度拟合成逆函数回归曲线,其全血质量分数都呈典型幂函数变化,其曲线回归方程分别为:哲罗鱼y=12.328x-0.1353,R2=0.9917;白点鲑y=7.8942x-0.1046,R2=0.9979;y=7.5059x-0.1062,R2=0.9931。统计分析表明:3种鱼Fb值呈显著性差异P<0.05;Tp差异不显著(P>0.05),但存在大小关系:白点鲑>美洲红点鲑>哲罗鱼;红细胞聚集性指数(A1、A2)相互之间差异不显著(P>0.05),白点鲑与美洲红点鲑之间红细胞刚性系数差异不显著(P>0.05),均与哲罗鱼呈显著性差异(P<0.05)。Blood physiological-biochemical indices in Hucho taimen,Salvelinus leucomaenis and Salvelinus fontinalis were determined.The whole blood viscosity was determined at seven shear rates of 5.75 /S,9.60 /S,11.50 /S,23.0 /S,46.0 /S,115.0 /S,230.0 /S while plasma was at the shear rate of 230 /S.Regression curve of inverse function was built by the result of the whole blood viscosity at different shear rates.It showed that the whole blood viscosity had a typical power function change and the curvilinear regression equation was that Hucho taimen y=12.328 x-0.1353,R 2 =0.9917,Salvelinus leucomaenis y=7.894 2x-0.1046,R 2=0.997 9,y=7.505 9x-0.1062,R 2=0.9931.The statistical analysis showed the 3 fishes had significant difference in the value of Fb P ﹤ 0.05,but not in that of Tp （P0.05）.The relationship of the Tp value in different fishes was Salvelinus leucomaenis Salvelinus fontinalis Hucho taimen.There was no obvious difference in the index of erythrocyte aggregation （A1,A2） of the 3 species of fish （P0.05） so as the rigidity coefficient of erythrocyte between Salvelinus leucomaenis and Salvelinus fontinalis.But they all had significant difference from the rigidity coefficient of erythrocyte of Hucho taimen.
