Economically important freshwater fishes infected with fungi causes EUS

Abstract

The aim of this study was to investigate fungal infections in Channa punctatus and Channa striatus twenty specimens of each species were studied for the presence of fungal infections. Infected fish’s shows clinical signs such as fungal growth on skin, fins, eyes, eroded fins and scales, hemorrhages on body surface and abdominal distension. The ability of aquatic fungi to cause diseases in fish is well known potentially all freshwater fishes their incubating eggs are susceptible to fungal infection. The most common fungal diseases of fish are saprolegniasis, disease caused by Achlya, branchiomycosis, epizootic ulcerative syndrome (EUS). Saprolegniasis is one of the most common infections of freshwater fishes in warm temperature and tropical waters; distributed throughout worldwide. Although there are many reports of different Achlya species infecting fish, there is no consistent and regularly observed clinical condition such as occurs with Saprolegnia. EUS is a seasonal epizootic condition of great importance in wild and farmed freshwater.
