ABSTRACT

Among the Indian major carps, Rohu is one of the most preferred species in the country and commands a higher price in the market. Aeromonas hydrophila bacterium causes disease in fresh water fishes and responcible for economic loss of the country. In present study the fishes were infected with bacterium Aeromonas hydrophila and various behavioural changes were observed. We found that the symptoms range from sudden death in otherwise healthy fish to lack of appetite, swimming abnormalities, pale gills, bloated appearance, and skin ulcerations. The skin ulcers may occur at any site on the fish and often are surrounded by a bright rim of red tissue. Aeromonas hydrophila causes disease in fish known as “Motile Aeromonas Septicemia” (MAS), “Hemorrhagic Septicemia,” “Ulcer Disease,” or “Red-Sore Disease.”
