A SURVEY ON THE DIVERSITY OF FRESHWATER CRABS IN SOME WETLAND ECOSYSTEMS OF BANGLADESH (Pages : 10 - 17)
M. A. RAHMAN, M. M. RAHMAN, A. T. A. AHMED, A. R. MOLLAH AND M. A. HOSSAINA survey was conducted in some wetland ecosystems located at the two Upazillas namely Shibalaya and Harirampur in Manikgonj District of Bangladesh during the period from January 2004 to January 2005 with a view to assess the status of freshwater crab resources in the area. The study was made on species diversity including its taxonomic position, morphometric and meristic characteristics, habits and habitat, distribution, and economic importance. A total of five species of crabs were recorded from the area namely, Sartoriana spinigera (Wood-Mason, 1871), Lobothelphusa wood-masoni (Rathbun, 1905), Acanthopotamon martensi (Wood Mason, 1875), Pyxidognathus fluviatilis Alcock, 1900, and Austrotelphusa transversa (von Martens, 1868). First three are belonging to the family Potamidae Ortmann, 1896 and the last two belong to the family Grapsidae Macleay, 1838 and Parathelphusidae Bott, 1970 respectively. Austrotelphusa transversa and Pyxidognathus fluviatilis are newly recorded species of freshwater crabs for the first time in Bangladesh. Among the recorded species, Sartoriana spinigera and Acanthopotamon martensi were found to be common but the rest three were uncommon. Download
