Protein banding pattern of eight snakeheads – Channa species viz., Channa striatus, Channa marulius, Channa punctatus, Channa diplogramme, Channa bleheri, Channa gachua, Channa stewartii and Channa aurantimaculata collected from different regions of India were used to study the phylogenetic relationship among them. The banding pattern from muscle protein indicated a unique profile for each spec...

The identity of snakehead fishes (Perciformes: Channidae) in India, particularly species belonging to Channa gachua complex remains to be confusing due to clubbing of a number of species under the synonymy of Channa orientalis Bloch and Schneider by several authors including Talwar and Jhingran (1991), Jayaram (1999) and Menon (1999) as well. Courtenay and Williams (2004) considered most of the...

Ammonia is the chief excretory product in fishes. However, non-availability of enough of water in the habitat, may lead to the formation of urea, in fishes. In the present study, the possible role of urea formation to avoid the toxicity of ammonia under water-restricted condition was tested in Channa gachua. Circulatory urea and ammonia were estimated in the blood of the fishes and glutamate de...

In search of other provitamins A, the metabolism of cryptoxanthin was studied in several species of freshwater fish, i.e. Channa gachua, Labeo boga (retinol-rich) and Heteropneustes fossilis (dehydroretinol-rich). The fish were either allowed to starve for 20-25 d to make their intestines free from carotenoids and vitamin A or kept on a vitamin-A-deficient diet for 140-150 d to deplete the init...

Heavy metals are considered as the most important pollutants of the aquatic environment. In the present study, acute toxicity test was used for the determination of lethal toxicity of Nickel in adult fish, Channa gachua as the test organism. Toxicity test is most reliable for accessing the adverse effect of pollutants on aquatic life. The LC50 values were determined and observed that the values...
