초록
2005년 8월1일 - 10월 22일까지 83일 동안 북서태평양 공해 40°-43°N, 150-155°E에서 원양오징어채낚기어업에 의한 어획시험 결과는 평균 38대의 자동조획기를 사용하여 총 4종, 47,524kg을 어획하였고, 단위노력당어획량은 8.9kg/lineㆍday이었다. 단위노력당어획량은 매월 수온 전선대를 형성하는 수역에서 높은 값을 보였다. 주 어획 대상종은 총 어획량의 96.8%를 차지하는 빨강오징어였으며, 그 다음이 문어오징어로 3.2%를 차지하였다. 동장은 조업 초기인 8월에는 작다가 시간이 경과함에 따라 점차 커졌으며, 사용낚시별 크기별 어획된 빨강오징어의 동장 역시 낚시 크기가 클수록 증가하였다. 오징어의 탈락률은 수중 탈락률이 28.2%로 가장 높았고, 다음으로 프론트 롤러 탈락과 공기중 탈락 순으로 나타났다.
Abstract
To investigate the catches of squid jigging fishery, a series of fishing experiments was conducted in the high seas of the Northwest Pacific(40°-43°N, 150°-155°E) during the period of 1 August to 22 October, 2005 by commercial fishing vessel. The number of 142 test fishing was carried out in the Northwest Pacific during 83days. The total catch were 47,524kg as 4 squid species and CPUE was 8.9kg/lineㆍday. CPUE showed high values in the frontal zone during the survey. Main squid species caught from the experimental fishing were the neon flying squid, Ommastrephes bartrami(96.8%) and the boreopacific gonate squid, Gonatopsis borealis(3.2%). Dorsal mantle length of the neon flying squid were increased by the time and increasing of the hook size. Loss rate of the neon flying squid in the water showed the highest values in 28.2% compare to the others. And the loss rate of the front roller and in the air were 1.1% and 1.0%, respectively.
