南方鲶血液的研究

测定了南方鲶血液生理指标及其季节变化,结果表明: 南方鲶血液的红细胞数量和血红蛋白含量高于鳙鱼、鲫鱼、团头鲂和日本白鲫等鲤科鱼类, 表现出与它凶猛的肉食性生活习性及生长快、 病害少等特点的一致. 在白细胞分类计数上,南方鲶属于以淋巴细胞为主, 嗜中性粒细胞和单核细胞均低,血栓细胞偏高的新类型. 红细胞数量、小淋巴细胞和血栓细胞百分比以及各种血细胞大小都表现出非常明显的季节变化.

Heamatological Study on Southern Catfish Silurus Meridionalis

From September, 1998 to August, 1999, the Heamotological indices of Southern catfish( Silurus meridionalis )are investigated. The result shows that the erythrocyte count and hemoglobin content value of Silurus meridionalis are higher than those of Aristichthys nobilis, Carassius auratus, Megalobrama amblycephala and Carassius auratus cuvieri , which indicates the consistency with its eating flesh habit and the features of fast growth and less disease. The differential leukocyte count is a new type, i.e., the kind that is composed mainly by lymphocytes, and has few neutrophilic granulocytes and monocytes and many thrombocytes. The erythrocyte count, the percentage of lymphocytes, the percentage of thrombocytes and the size of all the kinds of blood cells have significant year-round changes.
