The present paper deals with the piscicidal and muricidal (mice killing effect) activities of latex extract of Euphorbia royleana against freshwater snakehead fish, Channa punctatus and Swiss albino mice Mus musculus. Calculated values of lethal concentration (LC and LC ) showed that latex extract is toxic 50 90 against both the experimental animal. The toxicity of latex extract against freshwa...

Nuvan (DDVP) is a member of organophosphorus compounds. It is extremely toxic to insects and is widely used as insecticides. Nuvan has been taken for the acute toxicity to a fresh water fish Channa punctatus LC50 value calculated for the acute toxicity, which were 0.024 ml/L. Histopathological study of kidney and liver after 24hr, 48hr, 72hr and 96hr exposure to acute toxicity of Nuvan. Treatme...

In an aquatic environment, there is a profound and inverse relationship between environment quality and disease status of fish. Parasites are one of the most serious limiting factors in aquaculture. Therefore, the present investigation has been undertaken to sort out the population dynamics of Pallisentis (Acanthocephala), in relation to host sex from freshwater fishes, Channa of Rohilkhand reg...

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...

We sequenced the complete genome of the highly virulent Aeromonas schubertii strain WL1483, which was isolated from diseased snakehead fish (Channa argus) in China. The full genome sequence of A. schubertii WL1483 is 4,400,034 bp, which encodes 4,376 proteins and contains 195 predicted RNA genes.

background: acanthocephalans are fish parasites of worldwide distribu-tion, penetrate their thorny proboscis into the intestinal wall of host and absorb nutrients. no diagnostic tool is available except postmortem inves-tigations and identification by parasitologists. the aim of present study was to explore and assign taxonomical status to pallisentis species prevalent in food fishes of river g...
