In all over the world fish and its products are taken as food. Besides other sea foods, fish give the world basic supply of high grade protein, not only flesh as well as eggs and air bladder are also the best option for human being. Zoonotically fish transfer several diseases to humans through fish parasites. An immense deal of information on seasonal variation in the incidence and intensity of infection of fish with helminths has been accumulated form surveys and life-cycle studies made to recognize the factors responsible in the life-cycle of intermediate and definitive hosts and parasites.
