Macrobrachium snpurii sp. nov., collected from the Karamana River, in the lower reaches of Western Ghats, is described and illustrated. DNA barcoding using Cytochrome B gene sequences has elucidated the taxonomic status of the new species and the NJ tree reveals that M. snpurii sp. nov., is phylogenetically close to M. idella idella. However, morphometric and meristic features of the species sh...

N-ethyl-N-nitrosourea (ENU) mutagenesis is a useful approach for genetic improvement of plants, as well as for inducing functional mutants in animal models including mice and zebrafish. In the present study, mature sperm of grass carp (Ctenopharyngodon idellus) were treated with a range of ENU concentrations for 45 min, and then wild-type eggs were fertilized. The results indicated that the pro...

The current research was conducted with the aim to investigate rate of chromium accumulation in various tissues commercially valuable freshwater fish, Grass Carp, Ctenopharyngodon idella. Investigation included skin, muscles, liver, swim bladder, intestine, and gills fish. For this purpose, fish were exposed sub lethal concentration hexavalent form potassium dichromate a dose 120 mg/L for 40, 2...
