Sushama Kumari, Dina Nath Pandit

Abstract: The present work deals with histopathological alterations in the liver of an air breathing teleost, Channa gachua (Bloch) after getting an exposure to a biofertilizer (mustard oil cake). The 96hr-LC50 dose of mustard oil cake for fish was found 5065mg/L. In this study, fishes were exposed to 1 % and 5 % of 96hr-LC50 dose for 96hrs and 45 days to the biofertilizer and their light microscopically studies were made. It showed the oozing of blood from the capillaries, congestion of blood vessels, vacuole formation, vasodilatation, fatty changes and hypertrophy. The result showed that mustard oil cake is slightly toxic to the Channa gachua as it had caused mild degenerative changes in fish organs like liver. The results are significant from environmental pollution and human health point of view.
