Temperature fluctuations induced histopathological alterations in the liver of fish, Labeo boga inhabiting Jammu waters

Abstract

Presently an attempt has been made to elucidate the effect of temperature variance viz., 20 o C, 26 o C and 32 o C on the liver of fish, Labeo boga for the experimental period of 60 days. The stress of different temperatures induced various histopathological alterations in the liver tissue that ultimately disrupt the entire metabolic functioning of the fish. Where higher temperature (32 o C) induced only mild necrosis and increase in MMCS (to overcome the stress) in the liver while the stress of lower temperature (20 o C) resulted in necrosis followed by vacuolation and total degeneration of the tissue. The results are the clear indicative of the fact that lower temperature (20 o C) proved to be more deleterious to physiological functioning of the liver compared to higher temperature (32 o C).
