Stone Crabs
Carapace transversely oval or transversely hexagonal, front broad and not ched centrally, never produced in form of a rostrum; antero lateral margin lobate (in the species
listed herein) ortoothed; antennules folding transversely or obliquely. A single species
of interest to fisheries in the area: Menippemer cenaria Say, 1818 (Tavares 1998).
Ghost Crabs
Carapace usually rectangular or nearly so, ortrapezoidal; front relatively narrow and
somewhat bent downward; orbits occupying whole anterior border outside front,
outer walls of orbits often open, eyes talks long (longer than width of front); third
maxillipeds usually completely covering mouth cavity, concealing the mandibles;
dactyls of walking legs smooth or ridged but not conspicuously spiny (Tavares 1998).
2.2.2.4 Production and Trade of Crabs
Crabs are found in all the oceans of the world. There are also many kinds of freshwater and land-type. Annual production in world seas is around 1.6 million tons. It
constitutes 20% of all marine arthropods hunted all over the world. Crabs are found
in all the oceans of the world; There are also many kinds of freshwater and landtype. Annual production in the world seas is around 1.7 million tons. It accounts for
27% of all crustaceans caught all over the world (FAO 2016). Total world imports
of crab increased slightly to 294,000 tonnes during the first threequarters of 2017
compared to the same period in 2016. The main importers were the United States of
America (91,700 tonnes), China (59,900 tonnes), Republic of Korea (29,800 tonnes)
and Japan (29,200 tonnes). There were significant differences from country to country. Republic of Korean and Japanese imports fell by 8.1 and 16.7%, respectively,
while Chinese imports increased by 23.2% to almost 60,000 tonnes, and Thai
imports rose by 58.1% to 12,700 tonnes, during this period. Two of the most significant exporters of crab were the Russian Federation and China. In the Russian
Federation, exports of crab rose by almost 29%, to 44,000 tonnes, during the first
9 months of 2017. The main market was the Republic of Korea, with as much as
70% of these exports. In contrast, Chinese exports fell by 9.4% during the same
period. The Republic of Korea imported less Chinese crab, while Taiwan Province
of China imported slightly more (FAO-Globefish 2018).
2.2.2.5 Fishing of Crabs
The crab fishing season is between March and September. The most quantity of crab
is obtained between May and June. Fishing of crab is influenced by the movement
of the crab into the deep waters in winter and into the shallow waters in the spring.
