The present study was designed to investigate metazoan parasites from freshwater cat fish
Wallago attu. Nearly 123 specimens of Wallago attu were collected from Sunkesula reservoir
from January 2023 to February 2024. By the study it was observed that the fish were infested
with three species of ectoparasites namely ergasilus malnadensis (copepod), Thaparocleidus
indicus, Thaparocleidus wallagonius (Monogeneaus) and one endoparasite namely
Isoparorchis hypselobagri (Trematode) (Digena). The present study indicates the correlation
between the fish size and parasitic richness. It was observed that in small size host fishes the
parasitic number is less and in large size host fishes the parasitic number is more.
