The present study reports the parasitic isopod infection on commercial fishes of the northern part of the east coast of India collected during the period 2010-2015 from the marine waters of Odisha and West Bengal. During the study, 394 isopods were collected after examining 2668 fishes. These include 14 species of isopods, out of which 13 belong to 5 genera under the family Cymothoidae, and a single species belongs to the family: Aegidae. Of theses, 03 species viz., , and are first record to the northern part of east coast of India. Out of the 2668 fishes examined, 326 examples belonging to 34 species under 19 different families were infected by different isopods. Members of the host fish family Carangidae were more parasitized by isopods, followed by Clupeidae, Scoberidae, and Leiognathidae. The dominant isopods were and . The total prevalence was 12.21. The prevalence was high on the host fish and lowest on . The total infection caused by genus was 1.52%, was 5.07%, was 24.87%, was 0.25%, was 65.73%, and was 2.55%. The isopod prevalence was high during post-monsoon than pre-monsoon and monsoon.
