SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Portunus pelagicus

SPECIES NAME(s)

Blue swimming crab, Flower crab

In Thailand, P. pelagicus is distributed along the coasts of both the Andaman Sea (west) and the Gulf of Thailand (east) and is presently perceived and managed as a single unit. However recent analysis of genetic diversity and population differentiation originating from Ranong, Suratthani, Krabi, Prachuap Khiri Khan, and Chanthaburi suggested that BSC from these five different areas are regarded as different genetically isolated populations and should be treated as separate management units (Klinbunga, 2007). But this study only included one sample in the western coast, so one management unit is assumed given the lack of information..

This stock is part of a fishery improvement program (FIP).
