Abstract :

The present study is aimed to assess the histological changes in kidney caused to the fresh water fish, N. botia exposed to sub lethal concentration of Bis (tributyltin) oxide (TBTO). In this study, sub&ndash;lethal concentration is determined based on one tenth of lethal concentration. Light microscopic studies exhibited sever histopathological changes in the kidney. Increase in vacuolization, glomerulus shrinkage, damage to blood vessels, degeneration of tubules and necrosis with pycnotic were the most significant changes observed in fish kidney after Bis (tributyltin) oxide exposure. The effects were more pronounced in 96 hrs sub lethal concentration of Bis (tributyltin) oxide.
