The Antarctic krill Euphausia superba is important commercially and ecologically as a basic component of the Antarctic Ocean ecosystem. To manage this resource, it is important to determine the distribution and standing of krill in the water layer. Acoustic methods can capture information about the ...

남극크릴의 특징은? | 남극크릴(Euphausia superba)은 남극해에 서식하는 포유류 및 어류 등 상위 포식자와 식물플랑크톤과 같은 하위 포식자를 연결하는 해양 생태계의 먹이사슬의 관계에 중요한 역할을 하고, 남극해에 존재하는 동물플랑크톤 가운데 가장 큰 군을 형성하고 있다. 최근에는 건강식품과 약품 개발의 원료가 되는 등 미래 식량 대체 자원으로 각광받고 있다(Hewitt and Demer, 1993; Kang et al. | |
최근 각광받는 남극크릴의 용도는? | 남극크릴(Euphausia superba)은 남극해에 서식하는 포유류 및 어류 등 상위 포식자와 식물플랑크톤과 같은 하위 포식자를 연결하는 해양 생태계의 먹이사슬의 관계에 중요한 역할을 하고, 남극해에 존재하는 동물플랑크톤 가운데 가장 큰 군을 형성하고 있다. 최근에는 건강식품과 약품 개발의 원료가 되는 등 미래 식량 대체 자원으로 각광받고 있다(Hewitt and Demer, 1993; Kang et al., 1999; Everson, 2000; Kang et al. | |
동물플랑크톤 네트조사의 장단점은? | 남극크릴의 현존량 평가는 교정된 음향장비를 이용한 음향 조사를 수행하면서 과학어탐에 탐지되는 음향산란체의 종 식별을 위한 채집을 기본적으로 수행한다. 동물플랑크톤 네트조사는 채집된 종을 분류할 수 있고 정성적인 분석이 가능하나, 채집 시 유영생물이 회피를 하거나 조사 정점에 따라 많은 시간이 소요되는 단점이 있고, 음향기법을 이용한 자원량 추정 조사는 비교적 짧은 시간에 넓은 해역의 전 수층에 대한 정보를 알 수 있기 때문에 크릴의 시·공간 분포 및 현존량 평가에 많이 이용되어지고 있다(Lawson et al., 2008; Cox et al. |
