	Blue Crab 11 The Blue Crab 11, also called the Gloucester 11, is an American utility dinghy that can be rowed, used as a motorboat or as a sailing dinghy. It was designed by Harry R. Sindle and first built in 1971. The design is named for the family of crustaceans.Sherwood, Richard M.: ''A Field Guide to Sailboats of North America, Second Edition'', pages 8-9. Houghton Mifflin Company, 1994. Production The design was built by Lockley Newport Boats and Mobjack Manufacturing in the United States, but it is now out of production. Lockley Newport Boats was originally known as Newport Boats and later known as Gloucester Yachts. A total of 900 examples of then type were completed. Design The Blue Crab 11 is a recreational sailboat, built predominantly of fiberglass. It has a fractional sloop rig, with a loose-footed mainsail and aluminum spars, a raked stem, a plumb transom, a transom-hung rudder controlled by a tiller and a retractable daggerboard. It displaces . The boat has a draft of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Callinectes Sapidus ''Callinectes sapidus'' (from the Ancient Greek ,"beautiful" + , "swimmer", and Latin , "savory"), the blue crab, Atlantic blue crab, or regionally as the Chesapeake blue crab, is a species of crab native to the waters of the western Atlantic Ocean and the Gulf of Mexico, and introduced internationally. ''C. sapidus'' is of considerable culinary and economic importance in the United States, particularly in Louisiana, the Carolinas, the Chesapeake Bay, Delaware, and New Jersey. It is the Maryland state crustacean and the state's largest commercial fishery. Due to overfishing and environmental pressures some of the fisheries have seen declining yields, especially in the Chesapeake Bay fishery. Unlike other fisheries affected by climate change, blue crab is expected to do well; warming causes better breeding conditions, more survivable winters, and a greater range of habitable areas in the Atlantic coast. Whether this will have negative effects on the surrounding ecosystems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Cardisoma Guanhumi ''Cardisoma guanhumi'', also known as the blue land crab, is a species of land crab found in tropical and subtopical estuaries and other maritime areas of land along the Atlantic coast of the Americas from Brazil and Colombia, through the Caribbean and Gulf of Mexico, to the Bahamas, and north to Ponce Inlet, Florida Princess Place Preserve on the Palm Coast, and Bermuda. The species varies in colour from dark blue to brown or pale grey, and may grow to in carapace width and weigh over . Description The carapace of ''C. guanhumi'' can reach a width up to . As with many crab species, males possess dimorphic claws: the larger claw can grow up to around in length, eventually becoming larger than the carapace itself. The eyes are stalked and their colour ranges from a deep blue to a pale grey. Juveniles generally have a brown carapace with orange coloured legs. Females usually appear light gray or white. Adult colours are usually present between and . Individuals of the spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Paralithodes Platypus ''Paralithodes platypus'', the blue king crab, is a species of North Pacific king crab which lives near St. Matthew Island, the Pribilof Islands, and the Diomede Islands, Alaska, with further populations along the coasts of Japan and Russia. Although blue king crabs are among the largest crabs in the world and reputedly may exceed in weight, they are generally smaller than red king crabs. Fisheries Commercial blue king crab harvest around the eastern Bering Sea began in the mid-1960s and peaked in 1981 with a catch of . The Pribilof Island harvest by the United States peaked in 1980 at and was closed in 1988 due to population decline, then again in 1999 after being opened for three years. The St. Matthew fishery peaked in 1983 with but experienced a similar decline and was closed in 1999. It was opened in 2009, and was featured on the television show ''Deadliest Catch''. The St. Matthew stock is rebuilding but the fishery remains closed, while the Pribilof stock has not dras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Portunus Pelagicus ''Portunus pelagicus'', also known as the flower crab, blue crab, blue swimmer crab, blue manna crab or sand crab, ''rajungan'' in Indonesian, and ''alimasag'' in Tagalog, Kapampangan, and Pangasinan, is a large crab found in the intertidal estuaries around most of Australia and east to New Caledonia. Description The males are bright blue in color with white spots and with characteristically long chelipeds, while the females have a duller green/brown, with a more rounded carapace. The carapace can be up to wide. Behaviour They stay buried under sand or mud most of the time, particularly during the daytime and winter, which may explain their high tolerance to ammonium (NH4+) and ammonia (NH3). They come out to feed during high tide on various organisms such as bivalves, fish and, to a lesser extent, macroalgae. They are excellent swimmers, largely due to a pair of flattened legs that resemble paddles. However, in contrast to another portunid crab (''Scylla serrata''), they ...

	Portunus Segnis ''Portunus segnis'', the African blue swimming crab, is a species of crustacean, a swimming crab belonging to the family Portunidae. While native to the western Indian Ocean, it is also invasive in the Mediterranean. It is thought to have come through the Suez Canal from the Red Sea but it may have been transported by ships. Taxonomy ''Portunus segnis'' was first formally described in 1775 as ''Cancer segnis'' by the Swedish-speaking Finnish explorer, orientalist, naturalist, and an apostle of Carl Linnaeus Peter Forsskål with the type locality given as “Mari Rubro”, the Red Sea. It has been classified within the subgenus ''Portunus'' by some authorities. Until a review of the genus ''Portunus'' in 2010 ''P. segnis'' was considered to be a junior synonym of ''Portunus pelagicus''. The specific name ''segnis'' means “slow”, “torpid”, “lazy”, “unenergetic”, “tardy” or “inactive”, and Forskål described it as proceeding slowly in water ("''tarde ...
