鮸鱼血液生理生化指标分析

测定了象山港网箱养殖鮸鱼的血液生理生化指标.结果表明:雌鱼血液红细胞数显著高于雌鱼(雌鱼为2.58×106个·mm-3,雄鱼为2.30×106个·mm-3);其余血液生理指标在雌、雄两性间均不存在明显差异;白细胞数为2.365×104个·mm-3,其中以淋巴细胞含量最为丰富,达到(70±2.88)%,嗜中性粒细胞占(23.45±2.59)%,嗜碱性粒细胞含量最少,仅占0.2%.鮸鱼血液生化指标以乳酸脱氢酶LDH含量最高,达到(161.4±10.23)U·L-1;最低为尿素氮,仅(1.14±0.20)U·L-1;除Ca2+含量雌性显著高于雄性外,两性个体间其他各项血液生化指标均没有明显差异.

Blood Physiological and Biochemical Indices of Miichthys miiuy

Blood physiological and biochemical parameters of fish is an important reference to studying fish health, nutrition, reproduction and disease prevention and so on. In this research, we study the blood physiological and biochemical parameters of cultured Miichthys miiuy in Xiangshan Harbor. The results show that no significant difference in blood physiologicals is identified between female and male, except that the number of red blood cell in female is significantly higher than in male （2.58×106 mm-3 and 2.30×106 mm-3 in female and male, respectively）. In contrast, the number of white blood cell is 2.36×104 mm-3 in both genders. According to the leucocyte differential count, the percent of lymphocyte is the highest in white blood cell of Miichthys miiuy （70±2.88）%, and the percent of neutrophilic granulocyte is （23.45±2.59）%, and the percent of basophilic granulocyte is the lowest （0.20±0.42）%. In blood biochemicals, the content of lactic dehydrogenase （LDH） is at the highest level （161.4±10.23） U·L-1 and the urea nitrogen is at the lowest level （1.14±0.20） U·L-1. There is no significant difference of blood biochemicals between female and male, except that the content of Ca2＋in female is significantly higher than in male.
