Abstract

Aquatics provide nutrient rich, bioactive compounds to the mankind which are ecologically and economically sustainable. Specifically, Crustaceans are diverse group of marine and freshwater organisms, are increasingly recognized for their bioactive compounds with significant nutraceutical and pharmaceutical potential. Among crustaceans, crabs are major source of proteins, lipids, essential amino acids, vitamins, minerals, fatty acids [saturated fatty acids, unsaturated fatty acids]. Polyunsaturated fatty acids which include EPA and DHA which involves in reducing risk of coronary heart disease and cancer. It also acts as supplement for omega 3 fatty acids and exhibits antioxidant, antimicrobial, anti-inflammatory, and anticancer activities. Their shells provide valuable bioactive substances such as chitin, chitosan, carotenoids. Increasing awareness of the health benefits of crabs has expanded their export in various edible forms, such as frozen and canned meat. This growth underscores the importance of analysing the bioactive composition of crabs before consumption. This article primarily concentrates on four economically significant crab species from a broader range, specifically Portunus pelagicus, Scylla serrata, Scylla tranquebarica, and Charybdis feriatus.

Keywords: Portunus pelagicus, Scylla serrata, Scylla tranquebarica, Charybdis feriatus, Omega 3 fatty acids.
