Dejours, P. (1981). Farrelly, C.A. The blue swimming crab (Portunus pelagicus) is an important global fisheries resource because it has a high export value. Both species were having eight phyllobranchiatesas of the same structure but different in length and surface area. Three levels of water temperature (24 °C, 28 °C, and 32 °C) were used to determine their effects on the first 119 days of the crabs’ development after C8 stage in a recirculating aquaculture system. Mohamad N Azra1 and Mhd Ikhwanuddin2*.

Principles of Comparative Respiratory Physiology. Blue swimmer crabs (Portunus pelagicus) collected in three areas around Moreton Bay, Australia were examined for the presence of epizoic barnacles in their branchial chambers and on their carapace. De wetenschappelijke naam van de soort werd als Cancer pelagicus in 1758 gepubliceerd door Carl Linnaeus.. Portunus pelagicus is ook bekend als de blauwe zwemkrab. Female crabs possessed more species of parasites and symbionts, and had a more specialized fauna than did male crabs. Swimming crab samples were captured using gill nets with mesh sizes of 4 inches & net width of 80 cm. Tina, F.W. Evol. Entesar N. Sultan.
