Demographic pattern and digenetic trematode prevalence in Channa punctatus of Rohilkhand Region.

Abstract

Fish is a worldwide food staple and a pathogen-host. Most fisheries produce commercially valuable byproducts. Fish have ectoparasitic and endoparasitic diseases. Parasites play an important role in the growth of Fish & other animals. Considering that no systematic work has been done on trematode, and fish diversity of Rohilkhand, there is no record on the impact evaluation of parasitism in the fish trematode Community. Pathogens that cause disease are always present in aquatic environments or on fish. They only become manifest as different fish diseases when the host becomes more vulnerable and allows the pathogen to multiply in the fish body. Attempts have been made to study the biodiversity of trematode parasites linked to fish in various parts of the world.
