초록
본 연구는 양식 산업에서의 LED 광원의 적극적인 활용을 위한 기초 자료 수립을 목적으로 영상 분석을 실시하여 광파장 및 광강도에 따른 볼락의 행동 특성을 실험하고 분석 하였다. 실험을 위한 LED광은 1개의 적색광 (Wave length: 622 nm; Light power: 811 mW), 2개의 녹색광 (Wave length: 518 nm; Light power: 648 mW, Wave length: 518 nm; Light power: 810 mW)을 사용하였다. 볼락의 행동은 볼락의 5분간의 이동거리 (MD5)를 사용하여 분석하였으며, 먹이공급시의 평균MD5는 ch1, ch2, ch3 및 ch4에서 각각 20.0 m, 19.6 m, 16.3 m, 및 20.5 m이었다. 일출의 직전 및 직후의 채널 전체의 평균 MD5는 각각 6.3 m 및 8.2 m 이었으며, 일몰의 직전 및 직후의 채널 전체의 평균 MD5는 각각 13.6 m 및 12.0 m이었다. 실험①의 24시간의 평균 MD5는 ch1, ch2 및 ch3에서 각각 13.2 m, 9.6 m 및 6.8 m 이었으며, 실험②의 24시간의 평균 MD5는 ch1, ch2 및 ch3에서 각각 5.2 m, 3.8 m 및 2.9 m 이었다.
Abstract
In order to establish the basic data for the active use of the LED light source in the aquaculture industry, the experiment about the behavior of rockfish (Sebastes inermis) corresponding to the LED light was conducted by image analysis. LED lights for the experiment were one red light (wave length: 622 nm; light power: 811 mW) and two green lights (wave length: 518 nm; light power: 648 mW, wave length: 518 nm; light power: 810 mW). Behavior of the rockfish was analyzed using a moving distance (MD5) for 5 minutes where MD5s during the period of feeding were 20.0 m, 19.6 m, 16.3 m and 20.5 m in the ch1, ch2, ch3 and ch4. At the sunrise, mean MD5 of the entire channel about right before and right after were 6.3 m and 8.2 m. At the sunrise, mean MD5s of the entire channel about right before and right after were 13.6 m and 12.0 m. In the ch1, ch2 and ch3, mean MD5s during the period of 24 hours were 13.2 m, 9.6 m and 6.8 m at experiment 1and 5.2 m, 3.8 m and 2.9 m in the experiment 2.
