摘要

This research aims to examine the morphological characteristics of all the life stages of the isopod Nerocila orbignyi (Guérin, 1832), which parasitizes the host fish Plotosus canius Hamilton, 1822 (Gray eel-catfish) in Chilika Lagoon, Odisha, India. A detailed examination of the morphology, life cycle, and prevalence of the isopod N. orbignyi, was conducted following the standard protocols. The observations included 104 females, 32 males, 11 juveniles, and 47 embryonic stages. This study enhances our understanding of this species’ biology, making identification clear and straightforward. This study may be helpful in developing effective management strategies that could prevent isopod infections in aquaculture.
