Study of demographic pattern and prevalence of trematode parasite of digenia in Channa punctatus (Fresh Water Fish) of the Rohilkhand Region

Abstract

 Fish in a important article of food. It serve as a host to a number of pathogens. Most of the 
Fishes produce commercially most important by products. Fishes have ectoparasitic & endoparasitic 
diseases. Parasite produces an important role in growth of fishes and other animals. No systematic 
work has been done on trematodes and fish diversity of Rohilkhand region. So there is no record on 
impact evaluation of demographic parameter of parasite of fish community.
