Abstract

The Saemangeum Reservoir was constructed in 2006 as a part of Saemangeum reclamation project in which desalination has been also carried out. The purpose of this study is to provide basic data for predicting changes in fish distribution in the Saemangeum area with respect to the desalination processand to identify current status of fish distribution along with salinity levels. Fish sampling and measurement of salinity were conducted 4 times from February to October in 2012 at 10 sites within the Saemangeum Reservoir. A total of 71 species classified into 34 families were confirmed, and dominant and subdominant species were Thryssa kammalensis (16.1%) and Konosirus punctatus (12.8%), respectively. Saltwater fishes were still dominant at the Saemangeum Reservoir. Study sites were classified into four groups (A=St. 1, 6; B=St. 2, 3, 7, 8; C=St. 4, 9, 10; D=St. 5) by Bray-Curtis cluster analysis. Species composition of each group was closely related with salinity level: group A corresponding to 0.2 psu, B to 14.2 psu, C to 19.5 psu, and D to 23.5 psu.

새만금호는 새만금 간척사업을 통해 2006년에 완공된 인공 호로 현재 담수화가 진행되고 있다. 본 연구는 새만금호 내의 염도 별 어류분포를 확인하여 담수화가 진행되고 있는 새만금호의 어류분포 변화 예측에 도움이 되는 자료를 마련하고자 실시하였다. 어류조사는 새만금 호내 10지점에 대해 총 4회에 걸쳐(2012년 2월~10월) 어류군집과 염도를 조사하였다. 조사결과 전체지점에서 총 34과 71종이 채집되었으며, 우점종은 Thryssa kammalensis (16.1%), 아우점종은 Konosirus punctatus (12.8%)로 새만금호내 해양성 어류의 우점현상을 나타냈다. Bray-Curtis Cluster 분석을 실시한 결과 어류는 4개(A=St. 1, 6, B=St. 2, 3, 7, 8, C=St. 4, 9, 10, D=St. 5)의 그룹으로 구분되었다. Cluster 구분에 따른 지점별 평균 염도는 A=0.2 psu, B=14.2 psu, C=19.5 psu, D=23.5 psu로 차이를 보였으며, 그룹별 1차 담수어, 주연어, 해산어의 비율이 차이가 나타나 4개 그룹의 어류 분포는 염도에 따라 종의 구성이 달라지는 것을 확인할 수 있었다.
