[1] Carapace width is typically 150 mm (6 in), or exceptionally up to 250 mm (10 in). Metacarcinus anthonyi, the yellow rock crab or yellow crab, is a species of edible crab native to the Pacific coast of North America. [5] Females grow at about half the rate of males, [5] probably due to the energetic demands of egg laying. 1: 824 pp. A Common Name(s): Edible Crab, Brown Crab Scientific Name: Cancer pagurus Family: Usual Size: cm Largest Cromer Crab 280 mm. by a bottom trawl (out of Brixham) over sand or stones while out for a [4], The first pereiopod is modified into a strong cheliped (claw-bearing leg); the claw's fingers, the dactylus and propodus, are black at the tips. [3] A fold of the carapace extends ventrally to constitute a branchial chamber where the gills lie. [8] Their diet includes a variety of crustaceans (including the crabs Carcinus maenas and Pilumnus hirtellus, the porcelain crabs Porcellana platycheles and Pisidia longicornis, and the squat lobster Galathea squamifera) and molluscs (including the gastropods Nucella lapillus and Littorina littorea, and the bivalves Ensis, Mytilus edulis, Cerastoderma edule, Ostrea edulis and Lutraria lutraria). [11] The Norwegian catch is 8,500 tons annually, compared to 20,000 tons in the United Kingdom, 13,000 tons in Ireland, 8,500 tons in France, and a total 45,000 tons globally. [11] The fishery is widely dispersed around the British and Irish coasts, and C. pagurus is thought to be overfished across much of this area. Leewis, R. (2002) Flora en fauna van de zee [Marine flora and fauna]. [2], The first developmental stage after hatching is a planktonic larva (1 mm) called the zoea that develops into a postlarva (megalopa), and finally a juvenile. Linnaeus, C. (1758). Sexual maturity is reached at a carapace width of 12.7 cm (5.0 in) in females, and 11 cm (4.3 in) in males. [5] The main predator of Cancer pagurus is the octopus, which will even attack them inside the crab pots that fishermen use to trap them. [1], From the front, the antennae and antennules are visible. my hands. It is a flattened, reddish brown animal, up to 23 cm (9 in) long and 14 cm (6 in) wide, with flattened antennae and no claws. [21], International Code of Zoological Nomenclature, "Responsible Sourcing Guide: Crabs & Lobsters", "Systema Brachyurorum: Part I. 1-7: pag. [13], Around one third of the weight of an adult edible crab is meat, of which one third is white meat from the claws (see declawing of crabs), and two thirds is brown meat from the body. They live in all the world's oceans, in fresh water, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers.

C. pagurus is a nocturnal predator, targeting a range of molluscs and crustaceans. [2] The catch of C. pagurus has increased steadily, rising from 26,000 tonnes in 1978 to 60,000 t in 2007, of which more than 70% was caught around the British Isles. [2] Between 250,000 and 3,000,000 fertilised eggs[5] are held under the female's abdomen up to eight months until they hatch. [3] It is frequently found inhabiting cracks and holes in rocks but occasionally also in open areas. [13] Recent studies have shown that edible crabs are negatively affected by electromagnetic fields emitted from sub-sea power cables around offshore wind farms. Cancer pagurus, commonly known as the edible crab or brown crab, is a species of crab found in the North Sea, North Atlantic Ocean, and perhaps the Mediterranean Sea. [18], Although the genus Cancer formerly included most crabs,[19] it has since been restricted to eight species. Systema Naturae per regna tria naturae, secundum classes, ordines, genera, species, cum characteribus, differentiis, synonymis, locis.

Sexual maturity is reached at a carapace width of 12.7 cm (5.0 in) in females, and 11 cm (4.3 in) in males. for exceptionally large specimens and keep my camera and calipers close [11] The fishery is widely dispersed around the British and Irish coasts, and C. pagurus is thought to be overfished across much of this area. [19], Although the genus Cancer formerly included most crabs,[20] it has since been restricted to eight species. [2] The crabs are caught using crab pots (similar to lobster pots) which are placed offshore and baited. [1] The other pereiopods are covered with rows of short stiff setae; the dactylus of each is black towards the tip, and ends in a sharp point. with a carapace width of 292mm, and a weight of 14 lb, at a processors Accepted name: Cancer pagurus Linnaeus, 1758. Muller, Y. able to measure is a male from the collection of the Museum National d'Histoire Phillip Whelpdale the processors fishermen would probably hold back any really large males Beside these there are the orbits in which the eyes are situated. [2] Internal fertilisation takes place before the hardening of the new carapace, with the aid of two abdominal appendages (gonopods). Front with 5 blunt teeth, not produced beyond outline of carapace; anterolateral margin with 9 wide, blunt teeth with rounded tops, separated by closed fissures. Juveniles settle to the sea floor in the intertidal zone, where they stay until they reach a carapace width of 60–70 mm (2.4–2.8 in) and then migrate to deeper water.

Pesq. be properly documented and preserved! Cancer productus, one of several species known as red rock crabs, is a crab of the genus Cancer found on the western coast of North America. [1] Carapace width is typically 150 mm (6 in), or exceptionally up to 250 mm (10 in). We’re sorry, but GBIF doesn’t work properly without JavaScript enabled. It includes eight extant species and three extinct species, including familiar crabs of the littoral zone, such as the European edible crab, the Jonah crab and the red rock crab. 244 pp. It occasionally bears white patches, and is shaped along the front edge into nine rounded lobes, [1] resembling a pie crust. A mature adult may have a carapace width of up to 25 cm (10 in) and weigh up to 3 kg (6.6 lb). An intermediate value of 130 mm (5.1 in) is used in the rest of the North Sea between the 56°N and the Essex–Kent border, and in the Irish Sea south of 55°N. [10] Its parasites include viruses, such as the white spot syndrome virus, various bacteria that cause dark lesions on the exoskeleton, and Hematodinium -like dinoflagellates that cause "pink crab disease". on the large brown crab, a colleague here at Cefas has measured a crab
