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

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-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 ...

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...

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...

Effects of malachite green (Triarylmethane dye) and Pyceze (Bronopol) on the hematological parameters of a freshwater catfish Heteropneustes fossilis (Bloch)

Malachite green is an extensively used biocide in the aquaculture industry world-wide. It has been widely used due to lack of a proper alternative. Pyceze, however, is a pharmaceutical alternative to malachite green, with bronopol as its active ingredient. The catfish Heteropneustes fossilis were exposed for four days to 1/5th of LC50 values of each of malachite green (0.24mg/l) and Pyceze (0.4...
