Abstract

In Sarawak, razor clam has long been consumed as food. The collecting activity started from August to March the next scar. Asajaya had known as the major collecting site of three main species of razor clam: So/en regularis. S. sarawrakensis and S. digitalis in Kuching Bay. The population study of razor clam had been done within the harvesting season at five sites at Asajava nameh Movan Laut, Sambir, Sampun, Sebandi and Serpan, in order to collect and compile a baseline data on its diversiy. and density. Overall, the highest number of razor clam was found at Sambir (760 individuals) while the lowest recorded at Serpan (209 individuals). The highest density of razor clam /100 m2 was found at Sebandi 2 (154 individuals) while Serpan recorded the lowest (30 individuals). The study showed that S. regularis has the highest density compare to the other 2 species (96% are collected throughout the stud)). It can be found at every tidal level; high tide. mid-tide and lov, tide area. However, S sarawakensis and S. digitalis were mostly found at mid-tide and low tide area. The distribution pattern of razor clam also had been determined and mapped. Overall, the density was high at high tide area, and decreased towards loti tide area. Longest total length was found at S. sarawakensis, followed by S. digitalis and S. regularis. However, greatest total weight and shell width was found at S. digitalis, followed by S. sarawakensis and S. regularis. Individuals with greater length, width and weight were mostly found at low tide area while smaller size and weight individuals were dominant at high tide area fhe data collected were compared according to species and study sites. The baseline data is essential for future scientific development of selected species: behaviour, conservation, resource management and fishery.
