The mangrove shells is one of the economical fishery products and has high nutrition. One of the mangrove shell producing area is mangrove area of Kampung Bukit Tambun Tulang, Batang Kapas subdistrict, Pesisir Selatan regency. The decreased catch and the reduced mangrove shell population caused by the frequency of people that take mangrove shells and the damage of mangrove forest which is done continuously can affect the life of mangrove shells. Based on the background, the purpose of this research is to know the density of mangrove shells population (Polymesoda bengalensis Lamarck) in mangrove area of Kampung Bukit TambunTulang, Batang Kapas district, Pesisir Selatan regency. This research is done on March-April 2018 in mangrove area of Kampung Bukit Tambun Tulang, Batang Kapas subdistrict, Pesisir Selatan regency. The method used in this research is a descriptive survey. The technique of station determination is using purposive sampling by the consideration of environmental damage. The sampling is done at 2 stations, those are station I at mangrove area which had been cut down (wood is used) and station II at mangrove area which had not been cut down yet. The squared frame of 1m x 1m is put randomly as much as 20 squared frames in each station. The result of the research of mangrove shells population density (Polymesoda bengalensis Lamarck) in mangrove area of Kampung Bukit TambunTulang, BatangKapassubdistrict, Pesisir Selatan regency is 2,11 individual/m2. The condition of physical-chemical factor of mangrove area is still in tolerance range for the survival ofmangrove shells.
