Species composition and seasonal change were examined monthly with shrimp assemblage caught in the coastal waters of Solido, Korea. Samplings were conducted in Solido using a beam trawl from June 2000 to May 2001. In the study period, a total of 16 species of shrimp belonging to six families were collected. Species was dominated by Palaemon gravieri, Crangon hakodatei, Trachysalambria curvirostris and Metapenaeus joyneri. Higher abundance of shrimp occurred in September and November, and lower abundance in June. Species diversity was reached its maximum (0.82) in November and its minimum (0.06) in January. Shrimp species in the study area can be grouped into three groups on the basis of their occurrence patterns: resident, seasonal and temporary species.
