초록
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.
