Parasite Diversity and Histopathological Changes Due to Infection on Three Croakers (Pennahia Anea, Panna Microdon and Johnius Argentatus) of Saint Martin’s Island, Bay of Bengal

This study investigated the parasites of three species croakers (Pennahia anea, Panna microdon, and Johnius argentatus) their effect on host’s tissues. Fish samples were collected directly from local fishermen fish landing station Saint Martin’s Island, Bay Bengal a regular monthly basis. A total 448 individuals which nine identified including crustaceans, four nematodes, one pentastomida, acanthocephala. The nematode Procamallanus longus had highest prevalence (50%) intensity (10.33) compared with other parasites. slightly higher in female (55%, 35) than male (50%, 20). stomach liver most favorable infection sites (53.33%). Furthermore, largest length weight showed (66.66% 38.4 as well 80% 72.5, respectively). In histopathological investigations, important alterations various tissues hemorrhage, necrosis, fatty droplets, edema, vacuolar degenerations, missing villi, haemosiderotic nodules, ovarian follicle disruption, parasitic cell distribution.
