Abstract

Fish respond sensitively to light, so it is possible to develop fish management technology using this feature. In this study, we developed a light-based fish barrier and analyzed itsblocking effect using the difference in illuminance for the major fish species in Korea, bass and bluegill. The light was generated by a light emitting diode and the facility was installed vertically from the bottom. Considering the fish's ability to travel upstream, the flow rate was divided into three stages (0.2, 0.1, and 0.05 m/s). To prevent the learning effect, an experiment was carried out with fish that had rested for more than one day in a rearing tank. The experiment was carried out in such a way as tocompare the number of fish which travelled upstream after the introductionof the fish barrier and that of the fish which travelled upstream after itsremoval. It was also carried out after sunset to increase the effectiveness of the barrier. According to the results of the experiment, the fish blocking effect depending on the difference in illuminance was high and, overall, the blocking rate for bass was lower than that for bluegill. Based on the total size of the experimental population, the blocking rates for bass and bluegill were 96.33% and 99.00%, respectively. Based on the number of fish that travelled upstream, the blocking rates for bass and bluegill were 91.73% and 98.73%, respectively.

어류는 빛에 대해 민감한 반응을 보이므로 이를 이용한 어류 관리 기술 개발이 필요하다. 따라서 본 연구에서는 빛을 이용한 어류 차단 시설을 개발하였으며 국내 대표 외래어종인 배스와 블루길을 대상으로 조도 차이를 이용한 차단 효과를 분석하였다. 빛은 발광 다이오드를 이용해 발생시켰으며 바닥에서 수직 방향으로 향하게 설치하였다. 유속은 어류의 소상능력을 고려하여 총 3단계(0.2, 0.1, 0.05 m/s)로 구분하였으며 학습효과를 방지하기 위해 양육수조에서 1일 이상 휴식한 어류를 대상으로 실험하였다. 실험은 차단시설 적용 시 소상하는 어류 개체수와 차단시설 종료 후 소상하는 개체 수를 비교하는 방식으로 수행하였으며 차단 시설의 효과를 높이기 위해 일몰 후 수행하였다. 실험 결과 조도 차이에 따른 어류 차단효과는 높았으며 전반적으로 배스의 차단율이 블루길보다 낮았다. 전체 실험 개체수를 기준으로 배스의 차단율은 96.33%, 블루길의 차단율은 99.00%이며 소상 개체수를 기준으로 하면 배스는 91.73%, 블루길은 98.73%로 나타났다.
