The study was conducted during March 2011 to August 2011 in the east southern coastal area of Bangladesh marine territory to record landing trends, percentage composition and exploitation practice of marine swimming crabs from Shahparir dwip, Teknaf sadar, Shamlapur, BFDC fish harbour and Moheskhali fish landing centers at Cox’s Bazaar district. In this study three swimming crab species were recorded under the family Portunidae, such as- Blue swimming crab-Portunus pelagicus (Linnaeus,1758), Three spot swimming crab- Portunus  sanguinolentus (Herbst, 1783) are abundantly available and Cross crab- Charybdis  feriatus (Linnaeus, 1758) is found incidentally in the artisanal fishing. A total 74.650 MT of swimming crabs species were landed different select landing centers which exploited from the Elephant point area (in the Bay of Bengal) at Cox’s Bazaar district. In the total catch, highest landing amount was recorded 23.480 MT (31.45%) at BFDC fish harbour and lowest was 8.520 MT (11.41%) at Shaparir dwip landing center. The highest landing of catch per boat per day (CPUE) was 1.81 kg in Teknaf sadar landing center in May, 11 and the lowest CPUE was 0.18 kg in August, 11 at Shahparir dwip. Lower grade of male crabs were 30-80 gm in weight and female crabs were 40-90 gm constituted 18.0% and 24.0% respectively in total exploitation.

Keywords: Landing centers, Marine swimming crabs, exploitation practice, landing trends, percentage composition and Elephant point area.
