Final assessment
Explanation assessment

The fishing pressure on blue (swim) crab is too high at this moment, the stock of P. pelagicus is overfished in this area. Due to the short lifespan of crab and their fast reproduction, there is a chance for relatively fast recovery from overfishing.

There is no management plan made and the current management is not sufficient to protect this species. There are also no signs of a management plan on the short term.

 

General

Blue crab

The blue crab is also known as the horse crab, blue crab, blue swimmer crab and sand crab. There are two different species of the blue crab that have a very similar appearance. One occurs in the Indian Ocean and the Pacific whilst the other species occurs in the Atlantic Ocean. The blue crab is a relatively large crab with a carapace width of 20 centimetres. The crab has blue coloured legs of which the last pair is flattened and function as paddles for swimming. Another characteristic feature of the blue crab are the white spots on its carapace and two pointy extensions on both sides of the carapace.
