Vitamin D3- Induced Histological Changes in the Corpuscles of Stannius of a Freshwater Catfish, Heteropneustes Fossilis Kept Either in Artificial Freshwater, Calcium-rich Freshwater or Calciumdeficient Freshwater

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...

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 ...

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

Biochemical Changes in Blood of Freshwater Catfish Heteropneustes fossilis Exposed to Microcystin-LR

Present study reveals the effects of microcystin-LR (2.5 μg/25g bw) toxins on certain biochemical parameters in blood of H. fossilis. In treated fish serum bilirubin, serum cholesterol, serum creatinine and serum urea levels are increased. Serum protein content of treated fish is decreased. Present study suggests that MCLR is toxic to fresh water catfish Heteropneustes fossilis.

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...
