Ontogeny of the digestive tract in stinging catfish, Heteropneustes fossilis (Bloch) larvae

Microcystin-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 ...

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...

Endosulfan induced changes in phospholipids in the freshwater female catfish, Heteropneustes fossilis (Bloch).

The catfish, H. fossilis were exposed to endosulfan for 30 days at sub-lethal concentration (0.002 ppm) during different phases of its annual reproductive cycle. Its impact on total (TP) and different phospholipids- phosphatidylcholine (PC), phosphatidylserine (PS), phosphatdylinositol (Pl) and phosphatidylethanolamine (PE) were measured in liver plasma and ovary. On pesticide exposure, during ...

Testosterone 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 ...
