초록
양식산업에서의 어류의 성장의 기초자료를 성립하기 위하여, LED 광원에 노출된 어류의 행동을 분석하였다. 본 내용에서는 1개의 적색광 (광파장: 622 nm; 광파워: 811 mW), 1개의 녹색광 (광파장: 518 nm; 광파워: 648 mW)를 사용하였다. 볼락의 행동은 1분간 평균 이동 거리(AMD) 및 이동률을 이용하였다. 수온 및 LED 광원에 대한 볼락의 평균 AMD는 적색광, 녹색광 및 대조구에서 각각 1.5 m, 1.9 m 및 0.7 m 이었다. 수온 및 LED 광원에 대한 볼락의 평균 이동률은 적색광, 녹색광 및 대조구에서 각각 54%, 65% 및 45%이었다.
Abstract
In order to establish the basic data for the growth of fish in the aquaculture industry, the behavior analysis of rockfish (Sebastes inermis) depending on the temperature and LED lights was conducted. In this study, water temperatures were set from 3℃ to 30℃ were used. One red light (wave length: 622 nm; light power: 811 mW) and one green lights (wave length: 518 nm; light power: 648 mW) were used. Behavior of the rockfish was expressed as average moving distance (AMD) for 1 minutes and a rate of movement. The mean AMD depending on the temperature was 1.0 m and the mean rates of movement was 50%. The mean AMD were 1.5 m, 1.9 m and 0.7 m in the red LED light, green LED light and control condition respectively. The mean rates of movement were 54%, 65% and 45% in the red LED light, green LED light and control condition respectively.
