A Few Words About Crabs
Crabs are also used in bisque, a global dish of French origin. Crabs are known to work together to provide food and protection for their family, and during mating season to find a comfortable spot for the female to release her eggs
Crabs typically walk sideways (a behaviour which gives us the word crabwise). This is because of the articulation of the legs which makes a sidelong gait more efficient. However, some crabs prefer to walk forwards or backwards, including raninids, Libinia emarginata and Mictyris platycheles. Some crabs, notably the Portunidae and Matutidae, are also capable of swimming.
Crabs are mostly active animals with complex behaviour patterns. They can communicate by drumming or waving their pincers. Crabs tend to be aggressive towards one another and males often fight to gain access to females. On rocky seashores, where nearly all caves and crevices are occupied, crabs may also fight over hiding holes.
Crabs are omnivores, feeding primarily on algae, and taking any other food, including molluscs, worms, other crustaceans, fungi, and detritus, depending on their availability and eating its own the crab species. For many crabs, a mixed diet of plant and animal matter results in the fastest growth and greatest fitness.
Crabs make up 20% of all marine crustaceans caught, farmed, and consumed worldwide, amounting to 1½ million tonnes annually. One species accounts for one fifth of that total: Portunus trituberculatus. Other commercially important species include Portunus pelagicus, several species in the genus Chionoecetes, the blue crab (Callinectes sapidus), Charybdis spp., Cancer pagurus, the Dungeness crab (Metacarcinus magister) and Scylla serrata, each of which yields more than 20,000 tonnes annually.
