| 摘 要： | 对细鳞鲑和哲罗鲑的全血、血浆的理化特征及生理功能进行比较研究,结果表明,在8周的同等养殖条件下,细鳞鲑与哲罗鲑的SGR和DWG不存在显著性差异(P>0.05),均属健康状态下生长。血液生理学方面,细鳞鲑和哲罗鲑的红细胞形态均呈椭圆,细胞核呈长椭圆形;红细胞核体积分别为(50.12±7.85)μm3和(66.25±10.21)μm3。细鳞鲑与哲罗鲑的RBC、Hb、Hct、MCV和RDW存在显著差异(P<0.001),哲罗鲑的MCHC显著高于细鳞鲑的(P<0.01);这些血液生理学数据表明,细鳞鲑和哲罗鲑的耐低氧能力较弱。血液生化方面,细鳞鲑与哲罗鲑的Na+、P、AST、TG和CHOL存在显著性差异(P<0.05),且这几项指标前者均大于后者,这两种鱼的剩余其它生化指标均不存在显著性差异(P>0.05);血清底物浓度在正常范围内,AST和ALT可作为细鳞鲑和哲罗鲑的肝细胞损伤的特异性指标,且细鳞鲑的肝脏更容易受到损伤。

| Abstract: | The Brachymystax lenok and Hucho taimen were used to study the physiological and biochemical indices and physiological function of blood and plasma differences between them. The results indicated that these two fishes grew well under the same conditions for 8 weeks, and there were no significant differences between SGR and DWG (P>0.05). The erythrocyte of B. lenok and H. taimen were elliptic and the nucleus of them were long elliptic, with the erythrocyte volume of (50.12±7.85)μm3, (66.25±10.21)μm3, respectively. The RBC, Hb, Hct, MCV and RDW were significantly different between B. lenok and H. taimen, and MCHC of H. taimen were significantly higher than that of B. lenok (P<0.01). The results showed that B. lenok and H. taimen had poor capacity of dissolved oxygen tolerance. Na+, P, AST, TG and CHOL of B. lenok were significantly higher than H. taimen (P<0.05), while there were no significant differences of other biochemical indices between B. lenok and H. taimen. ASA and ALT can be specific indices of harmful hepatocyte, and the liver of B. lenok was easier to be damaged than H. taimen. |
