This paper was aimed to determine the population density of Saxidomus purpuratus according to the habitat environmental conditions of the southern coastal waters in Korea. The sediment type in Yeosu coast was dominated by silt (79.6 ± 0.5%), and followed by clay (19.7 ± 0.5%) and sand (0.7 ± 0.3%), and that in Geoje coast was similar to that of Yeosu coast (Silt 77.6 ± 0.4%, Clay 21.7 ± 0.7% and Sand 0.67 ± 0.4%). Thus the Saxidomus purpuratus habitat was mainly composed of silt. The population density of S. purpuratus in Yeosu coast was in the range of 0.5-2.0 ind./m2 and that in Geoje coast was 0.25-7.25 ind./m2. Among the caught individuals, the`proportion of immature individuals was 7.6% and 13.4% in Yeosu and Geoje coast, respectively.
