초록

낙동강 수계의 임하호에 서식하는 담수어류의 다양성과 종 목록을 고찰하고자 1992년부터 2016년까지의 문헌을 분석하였다. 그 결과, 임하호 내에서 출현한 전체 어류는 총 4목 11과 36속 46종 23,269개체가 보고되었다. 잉어과가 27종(58.7%), 미꾸리과 5종 (10.9%), 망둑어과 3종 (6.5%), 메기과, 꺽지과, 검정우럭과가 각각 2종(4.3%)씩 보고되었다. 우점종은 9,333개체 (40.1%)가 출현한 강준치였고, 아우점종은 2,281개체(9.8%)가 출현한 끄리로 나타났다. 우리나라 고유종은 17종으로 출현어종 46종의 37.0%를 차지하였고, 환경부 지정 멸종위기종은 3종, 국내이입종은 5종, 외래종은 3종이 보고되었다.

Diversity of fish fauna and species list collected from the Imha-Dam Reservoir of the Nakdonggang River system were reviewed based on the published materials from 1992 to 2016. As a result of the present study, 46 freshwater fish species/subspecies belonging to 36 genera, 11 families, 4 orders were reported in the Imha-Dam Reservoir. Of them, Cyprinidae occupied 58.7% (27 species), Cobitidae 10.9% (5 spp.), Gobiidae 6.5% (3 spp.), and Siluridae, Centropomidae, Centrarchidae were 4.3% (2 spp.) in the number of species, respectively. The dominant species in the number of individuals was Erythroculter erythropterus (40.1%, 9,333 inds.), and the subdominant species was Opsariichthys uncirostris amurensis (9.8%, 2,281 inds.). Among 46 species/subspecies, 17 species (37.0%) were identified as endemic species to Korea. Three species were endangered fish species by the Ministry of Environment of Korea, five translocated species, and three exotic species were reported.
