Abstract: A first hand preliminary inventory of fresh water crabs found in the Kanwar lake of Begusarai has been prepared on the basis of random sampling through aquatic net (having big mesh size). The population count of each crab species in each & every net sweep has also been done in order to prepare the species level population diversity. The article deals with statistical approach of crab species abundance & richness computed through the fundamental sampling data of the lake. The available food resources useful for the crabs and present in the lake have also been investigated. This exercise provides information about the ecological wellbeing of the lake with respect to the crab’s population & their available food resources.
