![]() This study reports the yearly occurrence and the biology of fisheries belonging to the blue crab Callinectes sapidus (Rath.) in the catch yield of Bardawil Lagoon (BL) in Sinai Peninsula, Egypt over the past 15 years. The present data are important for supplying biological information required for an adequate management of this fishery. The Callinectes species in Amazon estuaries are still poorly studied, and there is a need for monitoring their stocks due to its importance for artisanal fishery. Additionally, this study describes the first reference of CW/CLRs and CL/WRs for these portunid species in the region. These relationships are a useful tool for field ecologists to estimate length and/or mass of portunid species, and it is not necessary to euthanize the organism to collect body measurements. The variable most strongly related to CW was CL with 99 % of the variability provided by C. All species had strong relationships between measurements with a coefficient of determination (r 2) ranging between 0.97 and 0.99. A total of 85 crabs were collected between May and October 2015 in intertidal zones of the Caeté, Pirabas and Salinas estuaries. Milne Edwards, 1879, Callinectes danae Smith, 1869, and Callinectes ornatus Ordway, 1863 from the northern coast of Brazil. The maximumĪbundance of blue crabs was recorded at a salinity range from 24‰ to 25‰ and the waterĪbstract Carapace width-carapace length (CW/CLRs), carapace width-weight (CW/WRs), and carapace length-weight (CL/WR) relationships are presented for the portunid species Callinectes bocourti A. Size group of female blue crabs was 60–69 mm of CL and 120–129 mm CW. Group size of male blue crabs was the 61–70 mm of CL and 130–139 mm of CW. ![]() The sex ratio was found to be 1.28:1, in favour of males. The sex ratio of the blue crab’s population was assessed by a Chisquare PERMANOVA analysis, using the abiotic parameters as factors. The species’ ecological preferences at Papapouli Lagoon were assessed with The length–weight relationships were expressed by theĮquation W = aLb. AbioticĮnvironmental parameters were obtained. Papapouli Lagoon is in Thermaikos Gulf and is ecologically impacted by the blue crabs.įyke nets with a 20 mm mesh opening were soaked for 12 to 14 h during each survey. The aim of the present study is to report quantitative and qualitative data on theīlue crab’s biology and ecology in its non-native range, that are indispensable for management In the Mediterranean, itĪppeared around 1949 and though that it is established in East Mediterranean waters, relevant We promise to reward your interest with information designed to help you make a carefully considered decision regarding your financial management goals and about how our experienced advisory team – through personal, customized solutions – can help you effectively pursue those goals.Callinectes sapidus is native to the Atlantic coasts of the Americas.
