이매패류 패각운동 계측원리는 무엇인가? | , 2013). 계측원리는 이매패류 좌패각에 홀소자를 우패각에 자석을 부착시켜 개폐 거리에 따라 변화하는 자기력 값을 전기적 출력값으로 치환하여 패각운동을 측정하였다(Fig. 2). | |
고수온에 따른 폐사 방지를 위한 생물모니터링 시스템 설치 시 언제 조기 경보를 내려야 할까? | 이는 $30^{\circ}C$이상에서도 $20^{\circ}C$와 같은 신진대사를 보이는 개체군이 있었으나, 대부분이 신진대사의 활력의 감소에 기인하여 폐각상태가 지속되는 것으로 나타났다. 따라서 참굴 양식장에 고수온 감지를 위한 참굴 패각운동 BMS를 설치한다면, 경계단계는 빠른 패각운동(약 30.0회/hr 이상)일 때, 심각단계는 수시간 이상 폐각상태일 때, 조기경보(early warning)를 내릴 수 있을 것이다. 따라서 참굴 패각운동을 활용한 BMS는 이상고수온의 조기경보에 대하여 효과적으로 활용이 가능할 것으로 판단된다. | |
이매패류의 패각운동은 무엇인가? | 한편, 이매패류의 패각운동(Shell-Valve Movements; SVMs) 은 이매패류의 대사와 활동성을 대표하는 지표로 호흡, 섭식, 심박률 및 내인성리듬 등의 생리적요인과 포식자의 회피 및 자극 등의 외부적 요인에 따라 영향을 받는다(Rao, 1954; Langton, 1977; Ameyaw-Ajynfu and Naylor, 1987). 최근에는 이러한 이매패류의 패각운동을 이용하여 해양환경 변화를 파악하는 생물모니터링시스템(Bio-Monitoring System; BMS) 연 구가 활발히 수행되고 있다(Curtis et al. |
