Reproductive characteristics of the blue swimming crab, Portunus pelagicus (Decapoda, Brachyura: Portunidae) from the Bitter Lakes, Suez Canal, Egypt

Genetic population differentiation of the blue swimming crab Portunus pelagicus (Portunidae) in Thai waters revealed by RAPD analysis.

Genetic diversity and population differentiation of the blue swimming crab, Portunus pelagicus, in Thailand were analyzed by RAPD analysis. One hundred and twelve RAPD fragments were generated from 109 individuals of P. pelagicus using OPA02, OPA14, OPB10, UBC122, and UBC158 primers. The percentage of polymorphic bands in each geographic sample and that of each primer across overall samples wer...

Stock Assessment and Reproductive Biology of the Blue Swimming Crab, Portunus pelagicus in Bandar Abbas Coastal Waters, Northern Persian Gulf

Stock assessment and reproductive biology of the blue swimming crab, Portunus pelagicus, in Bandar Abbas coastal waters was conducted from August 2006 to July 2007. A total of 424 male and 348 female crabs were taken to the laboratory for length, weight and reproductive biometry. Estimate of growth parameter of crab showed t asymptotic carapace width (CW) was 172.5 mm, the curvature parameter, ...

Reproductive biology of the blue swimmer crab (Portunus pelagicus, Decapoda: Portunidae) in five bodies of water on the west coast of Australia

Portunus pelagicus was collected at regular intervals from two marine embayments and two estuaries on the lower west coast of Australia and from a large embayment located approximately 800 km farther north. The samples were used to obtain data on the reproductive biology of this species in three very different envi­ ronments. Unlike females, the males show a loosening of the attachment of the a...

morphometric characteristics of the blue swimming crab, portunus pelagicus (linnaeus, 1758) from the persian gulf, bandar abbas, iran

in this study, some external morphometric characters viz. carapace width (cw) and length (cl), chelar propodus width (chw) and length (chl) and abdominal width (aw) and also body weight (bw) of the blue swimming crab, portunus pelagicus (linnaeus, 1758), were examined. relative growth and regression slope compared among these parameters between 151 males and 158 females. specimens were collecte...
