Article
Hypoxia is a common stressor in aquaculture systems, which causes severe physiological disturbances, ultimately leading to mortality or reduced productivity. Arginine, as a precursor of NO, has a role in enhancing oxygen delivery. Thus, an experiment was conducted to evaluate the effect of dietary arginine (Arg) in Cirrhinus mrigala exposed to hypo...
Chapter
In recent decades, there has been increasing interest in the importance of radionuclide levels in the marine environment due to various accidents like Chernobyl and Fukushima, particularly in exportable and edible seafood products. These natural/manmade radionuclides accumulate in marine organisms and reflect difference in their diets. Therefore, r...

The Indian major carp, mrigal (Cirrhinus mrigala), is a bottom-dwelling fish that can survive hypoxic episodes in its natural environment. We hypothesise that it can better survive hypoxic conditions by altering metabolic responses through GABA (Gamma-aminobutyric acid) supplementation. In the first experiment, the hypoxia tolerance time of the fis...
