Not AvailableCrustaceans (shellfishes) are a large group of animals belonging to the sub phylum crustacea within the phylum Arthropoda. They are free living aquatic animals except for a few forms which are terrestrial and parasitic. Crustaceans also form an important group of genetic resources for aquaculture. The group comprises of several commercially important shellfishes like shrimps, lobsters, crayfish and crabs for human consumption and several tiny crustaceans like brine shrimp, copepods and cladocerans form valuable live food for commercial aquaculture. As per FAO, 62 different species of crustaceans were farmed globally in 2014 (SOFIA, 2016). This estimation mostly includes crustaceans produced for human consumption and the brine shrimp used as live food. The global crustacean aquaculture production in 2014 was around 6.9 million tonnes which is 9.3 % of the global aquaculture production excluding aquatic plants i.e. 73.8 million tonnes (FAO, 2016). However, the crustacean aquaculture production accounts for 22.6 % of the total value realised from global aquaculture. The global farmed shrimp production for the year 2014 was a staggering 4.58 million tonnes which is 66.37 % of the crustacean aquaculture production and 65.1 % of the value realised from crustacean farmingNot Availabl
