초록
고리 주변 해역에 서식하는 새우류의 종조성과 계절 변동을 알아보기 위해 1996년 1월부터 12월까지 소형 otter trawl을 이용하여 새우류를 매월 소조기에 채집하였다. 조사기간 동안 채집된 새우는 6과 11종이 었으며, 자주새우 (Crangon affinis)가 매우 높은 점유율로 연중 우점하였다. 출현량의 계절 변동을 살펴보면, 6
Species composition and seasonal variation of a shrimp assemblage in the coastal waters of Kori, Korea were studied based on the monthly trawled samples through a year of 1996. In the study period, 11 species of shrimps from 6 families were collected. Of these Crangon affinis predominated throughout the year. The peak abundances occurred in June and November, and low ones in winter and early autumn. More species were collected in winter and spring than summer and autumn. Species diversity indices showed that the shrimp assemblage was more diverse in winter than spring and autumn. Predominance of C. affinis in June, July and November caused high abundances and low diversity indices. The shrimps in the study area can be grouped into two groups on the basis of their occurrence patterns: resident species and seasonal species.
