Introduction: Human consumption on freshwater crab has increased day by day in world wide. As a whole, seafood products, freshwater fishery products like fishes, prawns, and crustaceans are commonly used. The nutritive value of crustacean’s meat has been extensively investigated in various parts of country. Chemical composition like proteins, fats, carbohydrates, minerals, vitamins etc. has great importance due to their nutritive role in human health. Freshwater crab is well known for having antioxidants, which reduces risk of chronic diseases including cancer and heart diseases. Crab meat consists of Omega 3 fatty acids, selenium, riboflavin, copper and phosphate that are useful for storage and absorption of iron.

Materials and Methods: In the present review the crab byproducts useful in regular diet of fisher tribes are highlighted. Our aim was to review on how to increase the population of black crab species through captive breeding and to determine the chemical composition and their current applications.

Results: The suggested captive breeding technique is one successful step towards captive rearing as backyard crab hatchery as nutritional security, instead of time spending hunting of this crab resulting in to its ecological vulnerability.
