摘要:Present survey was conducted to investigate physico chemical parameters in relation to Crab abundance in Gho-Manhasan Stream located in Western Region of Jammu. JandK (India). For this purpose, monthly sampling was done from two stations identified on the basis of the extent of anthropogenic activities. Physico-chemical parameters viz temp Air/Water, pH, DO, FCO, Cl- , Ca , Mg , HCO were assessed from Jan 2012 to Dec 2012. This water body harbours only one species of crab i.e. Paratelphusa masoniana. Population survey over a period of one year (Jan 2012-Dec 2012) revealed abundance of Crabs, to be more at station II as compared to station I as indicated by catch per unit. Presently, an attempt has been made to co-relate the observed variations with habitat disturbance. It was observed that total crab population exhibited a positive correlation to water temperature .009885, pH 0.338326, Dissolved Oxygen 0.174293, Calcium 0.056325 Magnesium 0.602844, while negative correlation was exhibited with chloride --0.00447, HCO- --0.245292 and FCO --0.396196.
