Callinectes similis ( englanti )

tarjonnut wikipedia EN

Callinectes similis, sometimes called the lesser blue crab[1] or dwarf crab,[2] is a West Atlantic species of blue crab. It was described by Austin B. Williams in 1966.

Description

Callinectes similis is a good swimmer, and its last pereiopods are expanded to paddles with which it swims. Adult males may grow up to a width of 122 millimetres (4.8 in), while females may reach 95 mm (3.7 in).[3]

Callinectes similis is most closely related to Callinectes danae,[4] a species also found in the Gulf of Mexico, but whose range extends as far south as Rio Grande do Sul,[5] and C. ornatus, a species found from North Carolina to Rio Grande do Sul.[6] C. similis is most easily separated from C. danae and C. ornatus by the form of the first and second pleopods in males.[7] It can be told apart from the more distantly related C. sapidus by the number of teeth on the front edge of the carapace, there being six in C. similis and only two in C. sapidus.[7]

Distribution

Callinectes similis is found in the Western Atlantic Ocean, Caribbean Sea and Gulf of Mexico from the United States to Colombia. It reaches its northern limit near Delaware Bay.[3] There has been considerable confusion between the various species of Callinectes, and it now appears that all individuals reported as C. danae and C. ornatus from the Gulf of Mexico (with the exception of parts of Florida) are actually C. similis.[7]

Ecology

Callinectes similis lives in marshes and estuaries, being the dominant crab in open bays. The species is limited to salinities of at least 15, and temperature may also affect reproduction.[3]

The diet of C. similis consists of a variety of foodstuffs, including plants, fish, polychaetes, other crustaceans including Farfantepenaeus aztecus and Portunus gibbesii, molluscs such as Mulinia lateralis, and detritus.[2]

Spawning takes place in the spring and fall, with females returning to estuaries to release their eggs.[3] Ovigerous (egg-carrying) females carry an average of more than 250,000 eggs.[2]

Fishery

Although it is not usually targeted because of its relatively small size, C. similis is sometimes caught alongside C. sapidus.[3]

Callinectes similis ( portugali )

tarjonnut wikipedia PT

Callinectes similis, às vezes chamado siri-azul pequeno [1] ou siri-anão, [2] é uma espécie de siri descrita em 1966.

Descrição

Callinectes similis é um bom nadador, e seu último par de patas funciona como remos, com os quais ele nada.

Os machos adultos podem crescer até uma largura de 122 milímetros, enquanto as fêmeas podem atingir 95 mm [3]].

C. similis é mais estreitamente relacionado com Callinectes danae,[4] uma espécie também encontrada no Golfo do México, mas cujo alcance se estende ao sul até o Rio Grande do Sul,[5] e Callinectes ornatus, uma espécie encontrada da Carolina do Norte até o Rio Grande do Sul.[6] C. similis é mais facilmente separado do C. danae e C. ornatus pela forma dos primeiro e segundo pleópodos no macho.

Distribuição

Callinectes sismilis é encontrado no Oceano Atlântico, Mar do Caribe e Golfo do México, dos Estados Unidos à Colômbia. Atinge seu limite norte, perto da baía de Delaware. Tem havido uma grande confusão entre as várias espécies de Callinectes, e agora parece que todos os indivíduos relatados como Callinectes danae e Callinectes ornatus do Golfo do México (com exceção dos partes da Flórida) são realmente C. similis.[7]

Ecologia

C. similis vive em pântanos e estuários, sendo o siri dominante nas baías abertas. A espécie é limitada pela salinidade, de pelo menos 15 ‰, e a temperatura também pode afetar a reprodução.[3]

A dieta de C. similis consiste em uma variedade de produtos alimentares, incluindo plantas, peixes, poliquetas, crustáceos, moluscos e detritos.[2]

A desova ocorre na primavera e no outono, com as fêmeas retornando aos estuários para liberar seus ovos.

Pesca

Embora não seja geralmente procurado por causa de seu tamanho relativamente pequeno, C. similis é por vezes capturado juntamente com C. sapidus.

小藍蟹 ( kiina )

tarjonnut wikipedia 中文维基百科
二名法 Callinectes similis
A. B. Williams, 1966[1]

小藍蟹學名Callinectes similis)是一種美青蟹屬物種[2]

特徵

小藍蟹最後的步足扁平,適合游泳。公蟹可以闊達12.2厘米,雌蟹則闊9.5厘米。[3]

小藍蟹的最為接近Callinectes danae[4]Callinectes ornatusCallinectes danae也在墨西哥灣出沒,更南至南里奧格蘭德州[5]Callinectes ornatus則分佈在北卡羅來納州至南里奧格蘭德州。[6]小藍蟹公蟹的第一及第二步足與C. danaeC. ornatus有所分別。[7]小藍蟹的甲殼上有6隻牙齒,而藍蟹的只有兩隻。[7]

分佈

小藍蟹分佈在大西洋加勒比海及由美國哥倫比亞墨西哥灣。其北方界限位於德拉瓦灣(Delaware Bay)。[3]美青蟹屬中的物種很易混淆,現時相信在墨西哥灣內(除了佛羅里達州)所有聲稱為C. danaeC. ornatus其實是小藍蟹。[7]

生態

小藍蟹棲息在沼澤河口,在海灣中數量最多。它們只限於不少於15‰鹽度的環境,而溫度也會影響繁殖[3]

小藍蟹主要吃植物魚類多毛類、其他甲殼類北褐蝦軟體動物侏儒蛤、及碎屑。[2]

小藍蟹會於春天冬天產卵,雌蟹會回到海濱帶產卵。[3]雌蟹平均可以帶著25萬顆卵。[2]

漁業

雖然小藍蟹並非主要漁獲,但有時也會與藍蟹一同被捕捉。[3]
