Effect of Arsenic (As2o3) on Haemetological Parameters of Freshwater Air Breathing Fish, Channa punctatus (Bloch)
Arsenic is a naturally occurring element found widely in the environment. However, on recent days the level of arsenic in the environment has increased several folds due to its use as pesticide, defoliant, electronics, thermal power plants, wood preservatives and metal industry. Arsenic has been reported as one of the most alarming chemical in the environment [1], present in different forms and...

Biomarkers of monocrotophos in a freshwater fish Channa punctatus (Bloch).
Activity of a few biomarkers have been investigated on freshwater fish Channa punctatus treated with monocrotophos for acute exposure to 18.56 ppm at 96 hr and subacute exposure viz. 0.46 ppm, 0.96 ppm and 1.86 ppm for 30 days. Biomarkers such as total protein, lipid peroxidation and acetylcholinesterase have been measured in different tissues of fish viz. gills, liver, brain and muscles. The p...
متن کاملIsolation, purification and characterization of the egg-yolk proteins from the oocytes of the indian freshwater murrel, Channa punctatus (Bloch).
In oviparous organisms, yolk accumulation in the oocytes is critical and indispensable for the development of the newly hatched young ones. In fish and many other oviparous vertebrates, the major constituents of the egg-yolk are synthesized as a precursor in the liver. The precursor is transported to the oocyte for uptake and cleaved into major yolk proteins lipovitellin, phosvitin and beta'-co...
