어류군집 분석을 통한 송천 수계 내 도암호의 생태학적 역할

초록

This study evaluated the ecological role of Lake Doam (in six sites: two upper reach points, two lake points, and two lower reach points) using the fish community distribution and eight matrices of fish assessment index (FAI) from June 2021 to October 2022. This research on fish community distribution identified three legally protected species at the lower reach points and two at the upper reach points. Concerning Korean endemic species, ten were identified at the lower reach points, whereas eight were identified at the upper reach points. The lower reaches attained approximately 16 points higher FAI than the upper reaches. The water quality analysis revealed that the quality of water of lower reaches was better than that of the upper reaches, particularly in terms of electrical conductivity and suspended matter. In conclusion, the purification actions such as sedimentation and dilution in Lake Doam had a positive effect on the lower reach points of the aquatic ecosystem.
