测定了5个不同盐度梯度(0、10、20、25、28)下分别饲养14d和21d的史氏鲟血液生理学参数。结果表明:在不同的饲养时间下,红细胞总数(RBC)、红细胞压积(HCT)、血栓细胞总数(PLT)、血红蛋白浓度(HGB)均随盐度的升高逐渐减少,红细胞平均体积(MCV)、平均血红蛋白含量(MCH)随盐度的升高逐渐增加,平均血红蛋白浓度(MCHC)无显著变化,红细胞体积分布宽度(RDW)、白细胞总数(WBC)、淋巴细胞数(LYM)、单核细胞数(MON)、嗜酸性粒细胞数(EOS)、中性粒细胞含量(NEUT)、嗜碱性粒细胞含量(BASO)随盐度的增加先升高后下降。在相同的盐度条件下,红细胞总数(RBC)、血栓细胞总数(PLT)、平均血红蛋白含量(MCH)、平均血红蛋白浓度(MCHC)、嗜碱性粒细胞含量(BASO)随养殖天数的增加逐渐下降,其它血液指标随饲养时间的延长逐渐升高。白细胞分类计数(DLC)值显示,在不同的盐度条件下,白细胞中各类细胞比例依次为淋巴细胞(Lym)>单核细胞(Mon)>嗜中性粒细胞(Neut)>嗜碱性粒细胞(Baso)>嗜酸性粒细胞(Eos)。通过盐度驯化后血液生理学分析,史氏鲟具有较强的渗透调节能力,经过驯化可以在28的盐水中生存。
The blood physiological parameters of Amur sturgeon were measured under 5 different salinity gradients (0, 10, 20, 25, 28) for 14d and 21d respectively. The results showed that RBC, HCT, PLT and HGB decreased with the increase of salinity at different feeding times. The average volume of erythrocytes (MCV ). The average hemoglobin content (MCH) increased gradually with the increase of salinity. The mean hemoglobin concentration (MCHC) had no significant change. The distribution of RDW, WBC, LYM, Cell number (MON), eosinophil count (EOS), neutrophil content (NEUT) and basophil content (BASO) increased first and then decreased with the increase of salinity. Under the same salinity conditions, RBC, PLT, MCH, MCHC and BASO gradually increased with increasing days Decline, other blood indicators increased with feeding time increased. The leukocyte count (DLC) values showed that under different salinities, the percentage of various types of leukocytes in order of lymphocyte (Lym)> monocyte> neut> basophilic Baso> Eos. After salinity domestication blood physiology analysis, Sturgeon has a strong osmotic adjustment ability, after acclimation can survive in the 28 of saline.
