Study of sodium arsenite induced biochemical changes on certain biomolecules of the freshwater catfish Clarias batrachus
Toxic impact of sublethal concentration (1 mg/L; 5% of 96h LC50 value) of sodium arsenite (NaAsO2) on certain biomolecules (proteins, nucleic acids, lipids, and glycogen) of five tissue components (muscles, liver, brain, skin, and gills) of the freshwater catfish Clarias batrachus was analysed. The important toxic manifestations include marked decrease in the concentration of proteins (21.72-45...
متن کاملEstimation of Acute Toxicity of Chromium to the Freshwater Catfish Clarias batrachus (Linn.)
Anthropogenic activities has increased the discharge of various concentrations of both essential and nonessential metals into aquatic ecosystems. The present study has been conducted to determine the median lethal concentration of chromium to the freshwater fish Clarias batrachus following standard procedures and was found that 40.56ppm, 38.15ppm, 36.65 ppm and 35.50ppm for 24h, 48h, 72h and 96...
متن کاملPesticides induced changes in circulating thyroid hormones in the freshwater catfish Clarias batrachus.
1. Effects of endosulfan, malathion and carbaryl on circulating T4, T3 and T3/T4 ratio in the freshwater catfish, C. batrachus have been studied during reproductively active phases, i.e. vitellogenic and post-vitellogenic phases of its annual reproductive cycle. 2. Endosulfan provoked a significant increase in T4 and a decrease in T3 as well as the T3/T4 ratio. 3. Malathion decreased T3 and T3/...

متن کاملAlterations in the Corpuscles of Stannius of Euphorbia royleana Treated Catfish, Heteropneustes fossilis
Background: We aimed to evaluate effect of Euphorbia royleana exposure on histocytology of corpuscles of Stannius in fish, Heteropneustes fossilis. Methods: Fish were subjected to 2.47 mg/L and 0.618 mg/L of E. royleana for short-term and long-term exposure, respectively. Blood samples were collected on 24, 48, 72 and 96 h in short-term and after 7, 14, 21, and 28 d in long-term experiment a...
