Population Dynamics of Helminth Parasites in Fresh Water Fishes Channa punctatus and Heteropneustes fossilis in Moradabad, U.P., India

In the present report two types of fish Channa punctatus (Bloch) and Heteropneustes fossilis (Bloch) were examined to explore the status of helminthic infection in fishes from various water bodies of Moradabad district.
