Histological alterations in the kidney of Nile tilapia (Oreochromis niloticus), exposed to Celecron 50EC

Abstract

Tilapia is widely cultured and most demandable fish species in Bangladesh as well as in the world. The current experiment was undertaken to investigate the histopathological conditions of the kidney of Nile Tilapia, Oreochromis niloticus after exposure to the pesticide Celecron 50EC. To determine the impact of histo-architectural changes in the kidney of the studied fish, the fishes were exposed to different sublethal concentrations of Celecron 50EC for 24, 48, 72, and 96 h. The kidneys of the treated groups showed highly deteriorated bowman’s capsule, necrosis, impaired renal tubules, pyknosis, vacuolization, damaged hematopoietic tissue, and necrosis. The current study demonstrated that Celecron 50EC harms fish organs.
