Abstract

A Korean trawl fishery was conducted on the Emperor Seamounts in the northwestern Pacific Ocean from 2005 to 2007. Total catches were 750 mt, 460 mt and 440 mt in 2005, 2006 and 2007, respectively. Splendid alfonsino (Beryx splendens) and North Pacific armorhead (Pseudopentaceros wheeleri) were dominant in the commercial fisheries on the Emperor Seamounts during 2005-2007. Biomass of each species was estimated by the swept area method from March 2005 to August 2007. During three years, average biomass of Splendid alfonsino and North Pacific armorhead were 791 mt and 266 mt, respectively.

2005년부터 2007년까지 북서태평양 황제해산해역에서 한국 트롤어업에 의해 어획된 어획 자료를 수집하여 어류종조성과 생물량의 시 공간 변동을 분석하였다. 어획량은 2005년에 750 mt, 2006년에 460 mt, 2007년에 440 mt로 어획되었다. 2005년부터 2007년까지 어획된 북서태평양 황제해산해역의 우점종은 빛금눈돔(Beryx splendens) 및 민사자구(Pseudopentaceros wheeleri)이었다. 직접자원량추정법인 소해면적법(swept area method)를 이용하여 빛금눈돔과 민사자구의 2005~2007년 동안 3년간 평균 생물량은 각각 791 mt과 266 mt로 추정되었다.
