花鲈溃疡病的防治研究

Study on Prevention and Cure of the Ulcerous Disease of Lateolabrax japonicus

在海水网箱养殖花鲈溃疡病的流行病学研究和病原菌的生物学特性研究基础上,进行养殖水域细菌学分析和防治药物的研究,提出了以生态防病结合药物防治的综合性防治技术。结果表明:依细菌数量的动态规律可预测鱼病的发生时期。环丙沙星、氯霉素、庆大霉素、磺胺+TMP、磺胺甲基异恶唑等可作为首选药物,联合用药效果更佳。试验点的花鲈成活率为93.9%～98.6%,比较同一海区另两个养殖点的成活率72.7%和37.5%分别提高了约23个百分点和58个百分点,表明综合防治技术应用试验效果显著。

On the basis of studies of the epidemiology and the biological characters of pathogenic bacteria about the ulcerous disease of Lateolabrax japonicus in marine net -cage culture,the bacteriological analysis of cultured waters and development of preventive medicine were carried out.Synthetical technique combining with medicines and ecology was presented for its disease.The result showed occuring period of its disease were prob-able forecasted on the variation of bacteria numbers.The chemotherapeutants of Ciprofloxacin,Chloramphenicol ,Gentamycinum,Sulfarmehoxazole /Trimethoprim,Sulfamethoxazole were first selected and the combination of them can achieve best results.Survival of cultured fish was93.9%～98.6%in testing area,which was23%and58%respectively higher than that of 72.7%and37.5%in two culture areas.The result showed that synthetical technique test has achieved remarkable success.
