Although, local consumption of this species is low, the species support a fast growing industry. Knowledge of natural diet in Portunus pelagicus is essential to understand its nutritional requirements, its interactions with other organisms and its potential for culture. Presence of the blue swimming crab (Portunus pelagicus) in the diet of the Pharaoh Eagle-Owl (Bubo ascalaphus) in Abu Dhabi, United Arab Emirates. (2010).

Hepatopancreatic sections of the swimming crab Portunus pelagicus juveniles in the control treatment (a, b), the 20% dietary soybean meal (SBM) treatment (c, d) and in the 100% dietary SBM treatment (e, f). The Journal of Raptor Research publishes the biology and conservation of diurnal and nocturnal raptors, such as their ecology, behavior, and conservation.
Relevant recreational fishing regulations for Australia (as of March 2016) are tabled below. They are found inshore on sandy and muddy habitats and among sea grass beds.
P. pelagicus is, however, easily distinguished because it have 4 frontal teeth (3 in P. trituberculatus) and it have 3 spines in the merus of chelipeds (4 in P. trituberculatus).

Obtained and accredited under fair use. Journal of Raptor Research, 42(1):70-72. The males are bright blue in color with white spots and with characteristically long They stay buried under sand or mud most of the time, particularly during the daytime and winter, which may explain their high tolerance to The species is commercially important throughout the These characteristics, along with their fast growth, ease of larviculture, high fecundity and relatively high tolerance to both The species is commercially fished in Australia, and is also available to recreational fishers and regulated by various state governments. Figure 2: Schematic diagram of Portunus pelagicus by Lai et al. The blue swimmer crab Portunus pelagicus has a wide geographical distribution and is an important commercial species throughout the subtropical waters and as such constitutes part of the fisheries resources. The natural diet of blue swimming crabs, Portunus pelagicus, was investigated from October 2008 to October 2009 using hand sampling and a crab gill net.The results showed that the major prey items in the stomach contents of P. pelagicus were teleost fish (29.61%), organic matter (20.69%), crustaceans (18.3%) and shelled molluscs (11.46%).
The natural diet of P. pelagicus was studied in Strait of Tebrau, Johor, Malaysia via gut content analysis and molecular analysis.
