Toxicity studies of butachlor to the freshwater fish Channa punctata (Bloch).
The toxicity studies were conducted on the fish Channa punctata (Bloch) by employing static and continuous flow through systems, for the toxicant butachlor (technical grade+) and its commercial formulation+ (machete 50% EC). The LC50 values are 297.89 ppb and 247.46 ppb for 24 hr and 48 hr in static for technical and 636.45 and 546.09 for machete. In continuous flow through the values are 270.0...
متن کاملEstimation of length-weight relationship and condition factor of spotted snakehead Channa punctata (Bloch) under different feeding regimes
Comparative study was conducted to observe the efficacy of different feeding regimes on growth of Channa punctata. Six iso- proteinous diets were prepared by using different agro industrial by-products. Maximum weight gain was recorded with diet having 66.75% rice bran, 11.50% mustard cake, 23.0% groundnut cake, 5% molasses, 1.5% vitamin-mineral mixture and 0.5% salt with specific growth rate o...
متن کاملBiomarkers of monocrotophos in a freshwater fish Channa punctatus (Bloch).
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...
متن کاملEffect of different protein levels on reproductive performance of snakehead murrel Channa striatus (Bloch 1793)
In this study the effect of different protein levels on reproductive performance of Channa striatus was conducted. Snakehead juveniles (65.5±0.2 g) were randomly distributed into nine homogenous groups of 75 fish each. Three isocaloric experimental diets differing in protein levels were prepared. The experiment lasted for 8 months and gonadosomatic index, absolute fecundity, egg diameter, numbe...
متن کاملNotes on Some Snakehead Fishes of India with an Aid to Their Identification
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...
