Description

The major objective of the research was to evaluate integrative impacts of fish movements and migrations after the constructions of weirs and fishways as a part of the "National River Restoration (NRR) Project" in Korean government. In the presentation, we introduce some plans and scales of the "National River Restoration Project" in Korea, and discuss some ecological problems on fish passage along with chemical water quality. The specific targets of our research are summarized as follows. First, fish species distribution and compositions were evaluated in the tributaries and mainstream sites of Yeongsan-River watershed after the completion of the fishway and weir constructions in migrations and fish passage in fishways and weirs. Third, we traced the passage of migratory and non-migratory fishes using various fish tracking methodologies including Passive Integrated Transpondents (PITs) tags, ultrasonic telemetry, video recording, trap-setting, and ultra eco-sounder monitoring approaches, and evaluated some impacts of the weir/fishway constructions. Lastly, we are trying to establish a "national protocol of fish monitoring methodology" for the surveys of the weirs and fishways in Korea. Currently, this study is on-going project in 2013 and will be continued until 2014. Our outcomes are preliminary results now, but will contribute to the ecological conservation of national rivers in Korea after the completion of our research.
