摘要
本文报导了病鱼的组织(肠、肝、胰、肾)病理变化,及血液(血清的钠、钾、氯化物、肌酐、尿素氮、谷草转氨酶总活力及谷草转氨酶同工酶。白细胞血式)病理变化,从而阐明了引起病鱼慢性死亡,而累计死亡率又高达60％的机理。查明了病原(崇明长棘吻虫)的中间寄主是模糊裸腹溞,找到了用生石灰或漂白粉清塘、在发病地区用鱼种池培育的鲤鱼鱼种的有效预防方法。
The parasite Rhadinorhynchus chongmingnensis infects the digestive tract of the carp, the intestines wall tissue is damaged immediately, a lot of epithelial cells proliferated from the intact tissues to cover damaged positions. At same time, the damaged tissues grow granulation tissue and form granuloma, and the adherence of internal organs occurred. Other organs of the diseased fish such as liver, pancreas and kidney are also damaged to varying degrees. The process of forming, developing and disappearing concerned with granuloma is observed and described.The contents of K, Na, Cl, CRE and BUN in serum of diseased fish are almost the same as the healthy fish. Only GOTs and no GOTm exists in the serum whether the diseased or the healthy fish, the total GOT actively in serum of diseased fish is distinctly higher than that of the healthy ones. The neutrophil content showed by percentage in leucocyte quantities of diseased fish is higher than that of healthy fish.The middle host of Rhadinorhynchus chongmingensis is Moina dubis. Using quick lime (CaO) or beaching powder (CaOCl_2) to sanitize fish pond before stock(?)ng is efficacious in prevention.
