초록

경남 고성군 당항만 하구에서 2011년 9월부터 2012년 8월까지 자연 하구인 배둔천 하구, 구만 마암천 하구는 소형 Beam trawl, 폐쇄 하구인 고성천 하구역에서는 투망으로 어류를 채집하였다. 염분은 폐쇄 하구가 자연 하구보다 변화 폭이 적었다. 자연 하구에서는 대부분 망둑어과 어류들이 채집되었으며 줄망둑(Acentrogobius pflaumi)과 문절망둑(Acanthogobius flavimanus) 순으로 우점하였다. 폐쇄 하구에서는 피라미(Zacco platypus)와 민물검정망둑(Tridentiger brevispinis) 순으로 우점하였고 담수 어종이 대부분 채집되었다. 당항만 하구역에 설치된 하구둑에 의해 염분을 포함한 환경조건이 바뀌어 서식하는 어류상이 크게 변화되었다.

The effect of estuarine dams on fish assembladge in Danghang Bay of Goseong, Korea was determined using monthly samples collected by a beam trawl and a cast net at the natural estuaries and damed estuary from September 2011 to August 2012. In the natural estuaries without dam, salinity was relatively high showing a large diurnal change. Estuarine fishes such as striped sandgoby, Acentrogobius pflaumii and yellowfin goby, Acanthogobius flavimanus, were dominantly caught in the sea side water. In the dammed estuary, freshwater species such as pale chub, Zacco platypus and triden goby, Tridentiger brevispinis were dominanlty caught. The dam in the Danghang estuary have significant effects on the fish assemblage through aquatic environmental change such as salinity.
