초록
동해안의 연안성 어족인 세고리물레고둥에 대해 망목 크기를 20mm, 35mm, 55mm, 75mm의 장구형 통발을 사용하여, 2003년 7월부터 2004년 3월까지 총 6차례에 걸쳐 포항 근처 해역에서 어선을 용선하여 행한 어획실험으로부터 어획노력량 및 샘플량이 다른 경우에 대해 SELECT 방법을 적용하여 망목선택성을 구한 결과는 다음과 같았다. 망목 20mm와 35mm 사이의 통발에서 어획 비율의 차이에 대해 특별한 경향은 발견할 수 없었다. 망목 크기가 20mm와 55mm 및 20mm와 75mm 사이의 통발에 대해 SELECT 방법을 적용한 결과, estimated split model이 equal split model 보다 모델 편차(model deviance)가 적어 더 적절하다고 나타났다. 따라서, 이 estimated split model에 의해 망목 55mm와 75mm의 경우의 50% 어획될 세고리물레고둥의 각고는 각각 65.4mm, 96.0mm였고, 망목 20mm에 대한 상대어획효율은 각각 0.48 및 0.25이었다.
Abstract
The mesh selectivity of drum net traps for Buccinum opisoplectum Dall caught in the eastern sea of Korea was described. Serveral experiment were conducted between July 2003 and March 2004 and the data obtained from the experiment was fitted by SELECT (Share Each LEngth class's Catch Total) model with unequal fishing and sampling efforts. The selection curve was determined to be 'estimated fishing efficiency' by model deviance rather than AIC. However a fishing efficiency between 20mm and 35mm mesh size did not seem to be different. The L50 lengths of the selectivity for the 55mm and 75mm mesh size were 65.4mm and 96.0mm, respectively.
