      <Abstract>Freshwater crabs have a great role in nutrient cycle in freshwater ecosystem, these species has a significant use as food in rural peoples. Recently these species are considered as bio-indicator in environmental monitoring. Some species of freshwater crabrecently found as carrier of paragonimiasis a serious disease caused by the Lung-fluke from Manipur and Arunachal Pradesh. Freshwater crab constitutes only a small fraction of the brachyuran fauna of our country. True freshwater crabs are those which spend their entire lives in freshwater without return to the sea for whatever reason. There are some crabs which occasionally wander or even live in freshwater habitats, especially those occurring near the sea, but they are always common in estuarine areas and their larval development occurs in the open sea. True freshwater crabs belong to two superfamilies viz. Potamoidea and gecarcinucoidea. All the members of the Potamoidea and Gecarcinucoidea spend their entire lives in freshwater or surrounding wetland area.The NortheastIndia are more considered as one of the global biodiversity hotspot of India,This area harbour a total 44 species of Freshwater crab, Among the total 96 species of Freshwater crab occurs in Indian Territory. A list of 44 species of crabs has been prepared with State-wise distribution in this region. Their economic use, Threats and conservation measures of these crabs are also discussed in full paper.</Abstract>
