Ecologicala Spectsin Relation to Digenean Trematodeparasites in Fresh Water Fish Channa Striatus (BLOCH)

Abstract

Fishes are found adequately in the different water sources of Jaunpur India. Five rivers (Gomti, Sai,Varuna,Pili and Basuhi) ,Gujar tal and different pond are available here as a aquatic habitat. In research work author consider only two sites of river Gomti and two different ponds in district Jaunpur, U.P. They are external as well as internal .In this studyauthor focused on digenetic trematodes parasites. Digenean trematodes are completing their life cycle in two hosts so both are susceptible to the infection. There are considerable change occur in the environment wih the passage of time. We also know that environmental factors affect the life forms of any place. So it is important to study the different ecological terms in relation to the host and their infectious agents. From ancient time humans beings use large amount of fish food for survival because they are easily available from different water sources. When human beings eat unadequate cooked fish then suffered with food borne tremadiases.So it is important to know the infection level in the fishes.
