Transportation Prototype for Live Distribution of Mud Crab in Seafood Supply Chain

Abstract

Mud crabs of the genus Scylla have been considered as a potential species for aquaculture and is widely regarded as one of the most promising alternatives to penaeid shrimp culture in crustacean fisheries. The development of mud crab fishery has been quite slow initially, compared to other exportable commodities like tuna and shrimp. But later, a shift in the scenario occurred on account of its enhanced demand in both domestic and export markets. Therefore, the development of proper transportation techniques became critically important and attempts were made in the mid-fifties to store live crabs in large tanks onboard fishing vessels, with continuous aeration, water circulation and temperature regulation of seawater (Roach, 1956). In India, mud crab marketing practices vary in different parts of the country. They are sold primarily in the live condition, although some are sold as frozen and as cooked products. These species fetch very high prices, where they are regarded as a luxury food.
