摘  要:本研究对奥利亚罗非鱼(Oreochromis aurea)(♀)×鳜(Siniperca chuatsi)(♂)远缘杂交子代(F2和F3)与双亲的血液常规参数和血液生化指标进行了比较,探讨杂交对子代血液学指标的影响。杂交子代具有两种来源,第一种的杂交母本为中心奥利亚罗非鱼(子代简称中心奥利亚杂交);另一种的母本为埃及奥利亚罗非鱼(子代简称埃及奥利亚杂交)。用于对照实验的母本为中心奥利亚罗非鱼。结果显示,中心奥利亚杂交F2与对照母本F2在2个血液常规参数和1个血液生化指标上存在显著差异(P<0.05),与父本鳜则有6个血常规参数和4个血液生化指标具有显著差异(P<0.05)。中心奥利亚杂交F3与对照母本F3在4个血液常规参数和2个血液生化指标上存在着显著差异(P<0.05),与父本鳜有6个血常规参数和4个血液生化指标具有显著差异(P<0.05)。埃及奥利亚杂交F2与对照母本F2在4个血液常规参数和4个血液生化指标上存在着显著差异(P<0.05),与父本鳜则有6个血常规参数和4个血液生化指标具有显著差异(P<0.05)。埃及奥利亚杂交F3与对照母本F3在2个血液常规参数和3个血液生化指标上存在显著差异(P<0.05),与父本鳜则有7个参数和3个血液生化指标具有显著差异(P<0.05)。不同品系来源的杂交后代中,2个F2群体在1个血常规参数和1个血液生化指标上具有显著差异(P<0.05),而2个F3群体仅1个血液生化指标具有显著差异(P<0.05)。研究结果表明,杂交子代与双亲在血液组成上均存在差异,但其更接近于母本。这些差异可能是由于杂交所引起的遗传结构变化所致。This research focuses on the haematological influence of distant hybridization by comparison on 9 haematological parameters which are haematocrit (HCT), hemoglobin (HGB), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), mean corpuscular volume (MCV), platelet (PLT), red blood cell (RBC), red blood cell distribution width (RDW), white blood cell (WBC) and 7 biochemical indices which are albumin, globin, Alb/Glo, glucose, total cholesterin, total grease, total protein between hybrid offsprings (F2 and F3) of Oreochromis aurea (♀) ×Siniperca chuatsi (♂) and their parents. Two strains of hybrid offspring were used in the study whose mothers were center O. aurea and Egypt O. aurea, respectively. Center O. aurea was the control. The results show there are significant differences on 2 haematological parameters and 1 biochemical index between center F2 (hybrid offspring of center O.aurea and S.chuatsi) and control mother F2 (P〈0.05), and 6 haematological parameters and 4 biochemical indices are significantly different between center F2 and father (P〈0.05). Furthermore, there are significant differences on 4 haematological parameters and 2 biochemical indices between center F3 and control mother F3 (P〈0.05). Between center F3 (hybrid offspring of center O.aurea and S.chuatsi) and father, significant differences on 6 haematological parameters and 4 biochemical indices are detected (P〈0.05). Moreover, Egypt F2 (hybrid offspring of Egypt O.aurea and S.chuatsi) is significantly different from control mother F2 on 4 haematological parameters and 4 biochemical indices (P〈0.05), and on 6 parameters and 4 indices from father (P〈0.05). There are significant differences on 2 haematological parameters and 3 biochemical indices between Egypt F3 and control mother F3 (P〈0.05), and on 7 haematological parameters and 3 biochemical indices between Egypt F3 (hybrid offspring of Egypt O.aurea and
