Size of Catch
These figures should be viewed as estimates because the various sources of such data varies significantly. What is interesting is the relative sizes of the catch and the approximate size of the catch.
These are world-wide catch numbers, and it should be kept in mind that the catch varies each year.
Crabs make up 20% of all marine crustaceans caught, farmed, and consumed worldwide, amounting to 1½ million tonnes annually.
One species,the Brown Crab (Portunus tritubercalatus) , accounts for one fifth of that total. Other commercially important taxa include the Flower Crab (Portunus pelagicus ), several species of Snow Crabs (in the genus Chionoecetes), the Blue Crab (Callinectes sapidus), Charybdis spp., the Brown Crab (Cancer pagurus), the Dungeness Crab (Metacarcinus magister) and the Mud Crab (Scylla serrata), each of which yields more than 20,000 tonnes annually.
