In fishes, parasitic diseases are very common and worldwide. The fish -parasite specificity depends on several internal and external factors including the environmental ones. The fish -parasite study is thus an important tool for assessing both the fish and environmental health. Bay of Bengal, Puri Coast Orissa, India is one of the important hotspots for pollution studies as it receives major rivers like the Ganga, the Brahmaputra, the Mahanadi, the Godavari and Krishna and the Kaveri. At site, various fish were analysed for the parasites using standard protocols.In presentresearch paper, Epinephalus marini n. g., n. sp is described from the intestine of a marine fish Epinephalus malabaricus.Thenew form belongs to the family Allocreadiidae (Looss, 1903) and differs from nearest genus Orientocreadium (Tubangui, 1931) in having aspinose body, terminal oral sucker, pre-pharynx absent, ceca simple terminating in the hind body, acetabulum sub-median extracecal situated in left part of the body al the level of cecal bifurcation and bilobed ovary and absence of laurer’s canal. The infection to marine fish Epinephalus malabaricus (reef cord) with parasite Epinephalus marini n. g. n. sp may be due to pollution especially due to hydrocarbon pollution in Bay of Bengal, Puri Coast Orissa, India.
