The compound crotocaudin extracted from the stem bark of the medicinal plant Croton tiglium Linn. was administered for 24 h or 96 h to the freshwater vector snail Lymnaea (Radix) acuminata Lamarck in order to test its toxicity. L. acuminata is the intermediate host of Fasciola hepatica and Fasciola gigantica which cause immense harm to man and his domestic animals. It was observed that the moll...

Different genetic biomarkers have been used to evaluate the mutagenic effects of pollutants such as agriculture pesticide and also a great variety of chemicals delivered on the environment by human activities. This way, the aim of present study was to evaluate the effect of agriculture pesticide in Channa punctatus through the micronucleus test as cytogenetic parameter and Haematological studie...

BACKGROUND Acanthocephalans are fish parasites of worldwide distribution, penetrate their thorny proboscis into the intestinal wall of host and absorb nutrients. No diagnostic tool is available except postmortem investigations 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 Gomt...

Changes in hsp gene expression profiles in murrel Channa striatus experimentally exposed to temperature stress (36°C) for 4, 15, and 30 days were investigated; fish collected from aquaculture ponds and maintained in laboratory at the pond temperature (25 ± 1°C) served as control. Channa collected from a hot spring runoff (36°C) was included in the study to examine the hsp profiles beyond 30 day...

Abstract Fish is generally appreciated as one of the healthiest and cheapest source of protein and it has amino acid compositions that are higher in cysteine than most other sources of protein. Heavy metals are natural trace components of the aquatic environment but their levels have increased due to industrial wastes, geochemical structure, agricultural and mining activities. All these sources...

Efficient management and prevention of species invasions requires accurate prediction of where species of concern can arrive and persist. Species distribution models provide one way to identify potentially suitable habitat by developing the relationship between climate variables and species occurrence data. However, these models when applied to freshwater invasions are complicated by two factor...

The present paper deals with the study of epizootic ulcerative syndrome on Hematological responses Fish Channa punctatus. A number fishes have been found to suffer from this epidemic disease. We are observed that decreases was due microcytic anaemia which in torn syndrome. Decrease count basophils, neutrophils and eosinophils fish punctatus malathion toxicity also observed.
