Abstract

Fish assemblages in the coastal waters off Gampo in the East Sea of Korea were analyzed using the samples of fishes collected with pot nets June, September, and December 2005 and March 2006. During the study period, a total of 19 fish species representing 10 families in 4 orders were collected. The fish assemblages predominantly consisted of Conger myriaster, which accounted for 38.9% of the number of individuals and 52.2% in the biomass. The next major specimens were Takifugu niphobles, Sebastes schlegelii, Chaenogobius annularis, Hexagrammos agrammus and Hexagrammos otakii. These five fishes accounted 44.1% of total number of individuals and 37.3% of total biomass. The number of fish species was the highest in March 2006 and the lowest in December 2005. The number of individuals and biomass were the highest in September in 2005 and the lowest in December in 2005.

동해 감포 연안에서 2005년 6월, 9월 및 12월, 그리고 2006년 3월에 통발에 어획된 어류 종조성을 분석하였다. 조사기간 동안 총 4목 10과 19종의 어류가 채집되었다. 채집된 어류 가운데, 가장 많이 채집된 종은 붕장어 (Conger myriaster)로서 채집 개체수의 38.9%, 생체량의 52.2%를 차지하였다. 그 다음으로는 복섬 (Takifugu niphobles), 조피볼락 (Sebastes schlegelii), 점망둑 (Chaenogobius annularis), 노래미 (Hexagrammos agrammus), 쥐노래미 (Hexagrammos otakii) 등이 비교적 많았다. 이 5종은 전체 개체수의 44.1%, 전체 생체량의 37.3%를 차지하였다. 종수는 2006년 3월에 가장 많았고 2005년 12월에 가장 적었다. 개체수와 생체량은 2005년 9월에 가장 많았고 2005년 12월에 가장 적었다.
