Dose- and time-dependent micronucleus induction in peripheral erythrocytes of catfish, Heteropneustes fossilis (Bloch) by zinc
As far as the detection of metal genotoxicity in fish is concerned, micronucleus (MN) test is considered an extremely suitable measure. In this study, frequencies of micronucleated erythrocytes were scored in peripheral blood of catfish, Heteropneustes fossilis (bloch) after acute in-vivo exposure of zinc at different concentrations (5, 10 and 30 ppm) in the laboratory condition. These three co...
متن کاملMicrocystin-lr Attenuates Blood Calcium and Phosphate Levels in Stinging Catfish Heteropneustes Fossilis
The present study was aimed to investigate the effects of microcystin–LR (MCLR) on the blood electrolytes of Heteropneustes fossilis. The fish were injected microcystinLR (2.5 μg/25 g) intraperitoneally at the initiation of the experiment. Blood samples were collected and the serum calcium and phosphate levels were estimated at 1, 3, 5, 10, 15 days. There is no change in serum calcium level of ...
متن کاملBacillus cereus infection in stinging catfish, Heteropneustes fossilis (Siluriformes: Heteropneustidae) and their recovery by Argemone mexicana seed extract
Mass mortality of stinging catfish, Heteropneustes fossilis, was observed in a fish farm of Kulgaria, Burdwan in West Bengal, India. The cumulative mortality rates reached up to 5% of the total fish in the farm per day. The clinical signs of the affected fish showed ulcers on the skin which gradually grew in size and progressed to form ulcerous dermatitis. Clinical signs of catfish experimental...

متن کاملTestosterone and estradiol-17 beta dependent phospholipid biosynthesis in ovariectomized catfish, Heteropneustes fossilis (Bloch).
Effect of cumulative doses (7, 14 and 28 mg kg(-1) body weight) of testosterone (T) and estradiol-17 beta (E2) on total phospholipids (TP), phosphatidylcholine (PC), phosphatidylserine (PS), phosphatidylinositol (PI) and phosphatidylethanolamine (PE) in tissues were investigated during the gonadal recrudescence, in prespawning phase of the annual reproductive cycle in intact and ovariectomized ...
