Stress of inorganic pollutant (Nitrate) Induced histopathological alterations in haemeopoetic tissues of Aspidoparia morar
Author(s): Sachar A, Raina S and Gupta K
Abstract: The present study examined the histological response induced by inorganic pollutant (nitrate) in a fish, A. morar inhabiting Jammu waters. LC50 value of nitrate for the studied fish was found to be 2 mg/l. The fish were subjected to three sublethal concentrations of nitrate viz., 25% (0.5 mg/l), 50% (1 mg/l) and 75% (1.5 mg/l) of LC50 value of nitrate were employed for the experimental duration of 9 weeks. The hemopoietic tissues were found to be totally damaged by the nitrate intoxication. Liver exhibited fibrosis, necrosis, steatosis followed by degenerative changes. Anterior kidney and spleen, however showed lymphocytic infiltration tubular necrosis followed by vacuolation and degenerative changes. The alterations observed were found to be responsible for hampering the entire metabolic machinery of the fish.
