Laboratory infection of three species of fishes with the water mold Saprolegnia parasitica and methods of their treatment

Three fish species (Cyprinus carpio, Ctenopharyngodon idella and Carrassius auratus auratus) were artificially infected with the fungus Saprolegnia parasitica. The infection was done under certain laboratory circumstances represented by a change in temperature (10, 15, 20, 25 30°C) nutrients (normal, decrease increase nutrients) constant pH. statistical analysis of results showed that influence on fungal dominant. Thus, when decreases, increases vice versa. Time less influential.The treated different remedial materials (sodium chloride, methylene blue, potassium permanganate, ketoconazole fluconazole). All these positive total treatment fishes but best sodium chloride at concentration 9%.
