Abstract

Parasitic fish diseases constitute one of the most important problems in fisheries sector. Among fish parasites, cymothoids are obligatory parasites, infesting mostly commercially important fishes. They are protandric hermaphrodites and blood suckers, living on the skin, gill filaments, or in the mouth of the fishes. These parasites retard growth and cause emaciation followed by death. Pathological conditions resulting from parasitic diseases assume high magnitude of epidemics under crowded and other unnatural conditions among fish.Isopod parasite of the family Cymothoidae under order Beloniformes have been reported from about 350 fish species and over 80% of these occurrence are from tropical and subtropical seas, majority being from the Indo-Malaysian archipelago (Lester, 1995).
