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. Temperature is an important factor that affects the immense response of the fish host, so indicated that outcome of temperature on the fish is an essential feature for the infestation rate of parasites. In the hot season the infestation rate was high. In some cases both trematodes and the pollutants could act together to cause tumorous growth, but it also appeared that combination of all these aspects has consist of mismanagement of marine resources and lack of enforcement of environmental laws which needed proper attention from the fisheries department and ministry of food and environment.
