This study was carried out on fish channa punctatus to investigate the lethal concentration of cadmium nitrate at 24 hr. Experiment procedure repeated five times selected concentrations, noting number killed. The mean value taken. These values were taken determine LC50 for Toxicity heavy metals it may be depends upon dose and time exposure period.

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...

This 3x3 factorial study assessed pyrethroids, carbamates and neonicotenoids groups of pesticides in replicated samples of three fish species from low (S1, reference), medium (S2) and heavy (S3) polluted sites receiving agricultural run-offs around the Indus River. Water and sediment samples from the same sites were also analysed for these pesticides by using high performance liquid chromatogra...

AIM The objective of this study is to gain a better understanding of the antimicrobial properties of the mucus extract of snakehead fish, Channa striatus against selected human and fish pathogenic microbes. MATERIALS AND METHODS The fish mucus samples were extracted with crude, acidic and aqueous solvents to identify potential antimicrobial agents including aqueous and acid soluble compounds....

Two experiments were conducted with a view to assessing the effects of stocking densities on the growth and breeding performance and larval growth and survival of Channa striatus. The first one was carried out with a view to find a suitable stocking density of Channa striatus at which they could spawn while the second experiment dealt with the effect of stocking density on growth and survival o...
