摘要
于1989至1992年对水库网箱养殖罗非鱼综合症各发病期、各症状型的病鱼进行了病理组织学研究。研究结果表明:网箱养殖罗非鱼综合症的病理基础是肝肾功能障碍,病鱼的肝、肾、脾、肠、鳃、性腺、脑均有不同程度的坏死或变性。本文还对细菌继发性感染,各症状型的病理学变化及防治对策作了讨论。
From 1989 to 1992, histopathological study on the syndrome of tilapia (Oreochramis spp.), cultured in netcages in freshwater reservoir, sampled from each outbreak of the disease, was performed. The results of the histopathological study indicated:Degeneration and necrosis in different degree were observed in liver, kidney, spleen, intestine, gill, sexual glands, brain of the diseased fish, and the blockages in the liver and the kidney functions are the pathological base of the syndrome of tilapia cultured in netcages. Bacterial secondary infection, pathological changes of each symptom and prevention and control of this disease are discussed in this paper.
