The freshwater fishes are an important source of animal protein to human population. They are adversely affected by aquatic pollutants such as pesticides used in agriculture, which are easily washed off into the water bodies. The effect may be direct when the pesticide is absorbed into the body through the skin, gill, intestine, wound, etc. It may be indirect when the pesticide alters the quali...

The study was carried out to identify muscle protein patterns and gut protease activity of rohu (Labeo rohita), catla (Catla catla), climbing perch (Anabas testudineus) spotted snakehead (Channa punctatus). Twelve percent Polyacryleamide substrate SDS-PAGE done visualize the enzyme after casein hydrolysis pattern species. Three alkaline proteases different molecular weight were observed in rohu...

The genotoxic and mutagenic potential of medicinal plant Jatropha gossypifolia, was investigated in fresh water fish Channa punctatus in the present study using micronucleus assay and comet assay. Fishes were exposed at 20% and 40% of the 24 h-LC50 value of plant extract containing Apigenin (76.48 mg L ) and crude latex (22.33 mg L). Both the test chemicals induced significant (P<0.05) genotoxi...

Population growth (length-weight relationship), and reproductive potential (e.g. fecundity, and sex-ratio) of five important fish species (‘mola’: Amblypharyngodon mola, ‘puti’: Puntius sophore, ‘tengra’: Mystus vittatus, ‘shing’: Heteropneustes fossilis and ‘taki’: Channa punctatus) collected from two important fresh waters bodies (namely Hilna beel and Beel Kumari beel) Rajshahi, Bangladesh, ...

The spotted snakehead Channa punctatus is a seasonally breeding teleost widely distributed in the Indian subcontinent and economically important due to high nutritional value. The declining population of C. punctatus prompted us to focus on genetic regulation of its reproduction. The present study carried out de novo testicular transcriptome sequencing during the four reproductive phases and co...

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...
