摘要

真菌感染是可养殖淡水鱼类中非常严重的疾病。本研究工作旨在调查从巴德拉水库项目(BRP)鱼种生产单位收集到的四种具有重要经济价值的淡水鲤鱼(Catla catla、Labeo rohita、Cirrhinus mrigala 和 Cyprinus carpio)的真菌感染情况。受感染的鱼类用聚乙烯袋收集起来,带到实验室进行真菌学研究。使用马铃薯葡萄糖琼脂和沙保德葡萄糖琼脂培养基分离真菌菌株。在 240 尾鱼类中,有 168 尾(70%)感染了六种不同的真菌属,分别是无患子属(54.167%)、青霉属(7.14%)、曲霉属(14.285%)、毛霉属(6.546%)、根霉属(4.167%)和粘孢属(13.695%)。这些真菌经常根据孢子结构和形态特征进行分离和鉴定。鲶鱼真菌感染的月变化和百分比为 35.10%,鲮鱼为 24.99%,鲤鱼为 21.41%,鲫鱼为 18.42%。冬季(57.5%)和雨季(39%)比夏季(10%)更有利于无患子的生长。为研究无患子对受感染鱼类的影响,进行了组织病理学研究。结果表明,鲶鱼比其他品种的鱼类更容易感染沙门氏菌。

Diversity of Fungal infections and Histopathological preparations of some economically important Fresh Water Fishes in Bhadra Reservoir Project, Karnataka, INDIA
Fungal infections are very serious diseases in culturable freshwater fishes. The present research work aimed to investigate the fungal infections in four economically important freshwater carps i.e. Catla catla, Labeo rohita, Cirrhinus mrigala and Cyprinus carpio which were collected from the Fish seed production unit at Bhadra Reservoir Project (BRP). The infected fishes were collected in polythene bags and brought for mycological study in the laboratory. The fungal strains were isolated using potato dextrose agar and Sabourd’s dextrose agar media. Out of 240 fishes, 168 (70%) infection have been recorded with six different fungal genera of Saprolegnia sp. (54.167%), Penicillium sp. (7.14%), Aspergillus sp. (14.285%), Trichoderma sp. (6.546%), Rhizopus sp. (4.167%) and Mucor sp. (13.695%). These fungi were frequently isolated and identified based on spore structure and morphological characteristics. The monthly variation and percentage of fungal infection in Catla catla was 35.10 %, Labeo rohita was 24.99%, Cirrhinus mrigala was 21.41% and Cyprinus carpio was 18.42%. Winter season (57.5%) and the rainy season (39%) was more favorable for the growth of Saprolegnia sp. than summer season (10%). Histopathological study was carried out to study the effect of Saprolegnia sp. on infected fish. Based on the results, Catla catla fishes were more susceptible to Saprolegnia sp. than other varieties of fishes.
