The present study aims to explore scientific knowledge about biodiversity of fresh water crabs in Surpul stream of district Harnai. Collection of Crabs was started from March 2017 to February 2018.Specimen collected from altitude ranging from 288 to 719 MASL (meter above sea level) covering 5 spots. Overall, five species of Crabs were collected in the investigated area such as, Himalaypotamon emphyseteum, Himalayapotamon atkinsonianum, Trichopotamon sikkimense, Liotelphusa quadrata, Maydelliatelphusa lugubris. A total of 142 crabs were collected among which Maydelliatelphusa lugubris is most dominant accounts to 64% followed by Liotelphusa quadrata accounts to 28.16% and Himlayapotamon atkinson with 2.11% of total collected. Statistical data indicates no significant difference in diversity among 5 spots. However considerable difference was observed in altitude range of sampling area. Due to lack of facilities traditional hand-picking method was used for collection of specimens.
