초록

본 연구는 자연에서 채집한 불볼락(Sebastes thompsoni)을 대상으로 고 수온 노출에 따른 생물의 행동반응 및 내성 한계(tolerance limit)를 규명하기 위하여 연속적으로 행동관찰이 가능한 추적시스템을 사용하여 노출 수온구간별 행동패턴의 변화, 임계 수온범위 및 아치사 행동반응을 분석하였다. 실험 결과, 대조수온(15.0℃)을 20.0℃로 높였을 때, BI (behavioral index)는 노출 초기 10시간 동안 일시적으로 증가하였으나 60~70시간 동안 뚜렷한 행동의 변화 없이 일정한 속도로 안정된 유영 패턴을 보였다. 그러나, 25℃에서는 활동량의 급격한 저하, 30℃에서는 활동성 지연과 정지행동 등과 같은 비정상적 유영 및 대사활동 교란이 확인되었으며, 온도의 상승에 따라 개체의 사망률이 높아지는 경향을 보였다. 이러한 결과는, 불볼락의 수온에 대한 내성한계는 25.0~30.0℃이며 생존에 큰 영향을 미치는 수온은 30.0℃ 부근임을 나타낸다. 본 연구의 결과가 효과적인 불볼락의 양식을 위한 환경 조건 설정에 도움을 줄 것으로 기대한다.

To investigate the tolerance limit and critical thermal maximum (CTM), behavioral responses of wild goldeye rockfish Sebastes thompsoni according to exposure to high water temperature were observed using a continuous behavior tracking system. As a result, behavioral index (BI) of S. thompsoni in each temperature (20.0, 25.0, and 30.0℃) showed a significant difference (p<0.05) when compared with the value measured in a stable condition of 15.0℃. The activity level of S. thompsoni exposed to 25.0℃ decreased sharply after 20 hours. Their rest time at the bottom of experiment chamber increased, and their normal swimming and metabolic activities were disturbed. In addition, at a high water temperature of 30.0℃, S. thompsoni reached the limit of resistance and showed a sub-lethal reaction of swimming behavior, with energy consumption in the body increased and all test organisms died. In conclusion, the eco-physiological response of S. thompsoni to water temperature varied greatly depending on the fluctuation range of the exposed temperature and the exposure time. In addition, the tolerance limit of S. thompsoni to high water temperature was predicted to be 25.0-30.0℃. The maximum critical thermal that had a great influence on the survival of this species was found to be around 30.0℃.
