Abstract
The seasonal changes in species composition of fishes in Kwangyang Bay were determined using bimonthly samples with a bottom trawl at five stations from February to December 1990. A total of 32 families 54 species, 9,497 individuals, and 65,838.2g of fishes were collected. Leiognathus nuchalis occupied 64.9% of the total number of individuals. L. nuchalis and Konosirus punctatus occupied 28.8% and 22.3% of the total biomass, respectively. The number of species, the number of individuals and the biomass were lowest in February. More than 20 species occurred during the period when the water temperature was higher than
광양만 어류의 종조성과 계절변동을 파악하기 위하여 1990년 2월부터 12월까지 5개 정점에서 격월로 소형 저인망을 이용하여 어류를 채집하였다. 조사기간 동안 총 32과(科) 54종(種), 9,497개체, 65,838.2g이 채집되었다. 주둥치(Leiognathus nuchalis)가 총 개체수의 64.9%를 차지하였으며, 주둥치와 전어(Konosirus punctatus)가 각각 총 생물량의 28.8%와 22.3%를 차지하였다. 수온이 낮은 2월에는 출현종수와 개체수, 생물량이 모두 연중 가장 낮은 수준을 보였다. 수온이
