This study conducted a survey using a sampling inspection method and acoustic technique for continuous monitoring of useful organisms and non-commercial fish species distributed in the water of Gwangyang Bay, and evaluated the marine resources. In June, 2018, 38 species were caught in the shrimp bea...

새우조망 어업이란? | , 2013). 새우조망 어업은 자루그물 양쪽에 달린 날개그물 사이에 막대를 부착하여 자루그물의 입구가 일정하게 벌어지게 한 어구를 한척의 어선이 저층을 끌어 갑각류를 어획하는 어업을 말한다. 다른 어업에 비해 그물 망목의 크기가 작아서 어업 시에 목적어인 새우류 보다 부수 어획물의 비율이 높지만(Slavin, 1982; Alverson et al. | |
조사 어구를 이용한 방법의 장단점은? | 한편, 조사 어구를 이용한 방법은 종을 명확하게 규명할 수 있는 장점이 존재하나 환경적 영향에 따라 어구 설치의 어려움이 있으며, 조사 정점이 불충분 하고 시간적, 경제적으로 어려움이 많다. 수산 자원의 관리 및 평가는 대상으로 하는 수산생물 자원의 현존량을 추정하는 것이 기본인데(Yang et al. | |
음향 기법의 시스템과 해석기법의 발전을 통해 얻을 수 있는 것은? | , 2015). 이러한 음향을 이용한 조사방법은 짧은 시간에 넓은 수층에 대한 정보를 얻을 수 있다는 장점이 있으며, 수산생물의 수직 및 수평 분포와 같은 다양한 정보를 얻을 수 있다(Lawson et al., 2008; Cox et al. |
