Temporal expression of thyroid hormone regulating genes (tsh-b, tsh-r, dio2 and dio3) and their correlation with annual reproductive cycle of the Indian freshwater catfish, Heteropneustes fossilis (Bloch).

Histological Studies on Kidney of Cadmium Chloride Exposed Freshwater Catfish , Heteropneustes Fossilis ( Bloch )

Acute toxicity bioassay of dimethoate on freshwater airbreathing catfish, Heteropneustes fossilis (Bloch).

Pesticides are chemicals used for pest control in the agricultural fields. They finally reach the surrounding water bodies through surface runoff affecting the aquatic fauna. Dimethoate is frequently used organophosphate pesticide due to its high effectiveness and rapid breakdown into environmentally safe products. A 96 hr static acute toxicity test was carried out to determine the LC50 value o...

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 ...

Microcystin toxicity in a freshwater fish, Heteropneustes fossilis (Bloch)

Microcystin is a toxin secreted by cyanobacteria, which are the dominant phytoplankton in eutrophic freshwater bodies. The present study reports histopathological, hematological and biochemical changes in the freshwater fish, Heteropneustes fossilis due to toxicity of microcystin. Toxic effects were observed in liver, kidney, corpuscles of Stannius, gills and gonads. Bilirubin concentration inc...

Microcystin-LR: Effects on Freshwater Catfish Heteropneustes fossilis Prolactin Cells

Background: Previous studies have been reported on the toxicity of Microcystin-LR, which is produced by cyanobacterial growth in fish, such as Heteropneustes fossilis (H. fossilis). However, no studies have been conducted on the effects of Microcystin-LR on the prolactin cells of H. fossilis. Methods: H. fossilis fish were intraperitoneally injected with Microcystin-LR (2.5μg/25g) and sacrif...
