초록
우리나라 동해안에 분포하는 도루묵의 분포 특성에 대하여 2004〜2008년까지 자망어업과 동해구기선저인망어업의 해구별 어획량을 이용하여 분석하였다. 도루묵은 동해구기선저인망어업과 자망어업에 의해 주 어획이 나타났다. 동해구기선저인망어업의 주 어획기간은 4〜10월로 나타났고, 자망어업의 주 어획기간은 10〜12월로 나타났다. 동해구기선저인망어업의 어장은 동해안 전 연안에 걸쳐서 형성되었고, 분포중심은 2004〜2005년에 비해 2006년에 들어 수온의 상승과 함께 도루묵의 어장이 연도별로 점차 북상하는 경향을 나타내었다. 자망어업의 어장은 대부분 강원도 연안에서 형성되었고, 2006년부터는 수온의 상승에 따라 점차 북상하는 경향을 나타내었다. 도루묵의 분포는 여름철에 강원도에서 울산까지 넓게 분포하였고, 가을철에는 산란장인 강원도 연안으로 회유하였다. 동해구기선저인망어업과 자망어업의 공동신뢰영역에대한 면적당 CPUE는 면적이 넓어질수록 면적당 CPUE가 작아지는 역상관계를 나타내었다.
Abstract
Distribution pattern and fishing conditions of sandfish, Arctoscopus japonicus in the East Sae were explored using catch and catch per unit effort (CPUE) by eastern sea Danish seine and coastal gill net fisheries from 2004 to 2008. A. japonicus was one of major target species for the eastern sea Danish seine and coastal gill net fisheries in the East Sea, which were caught from April to October for the eastern Danish seine, and from October to December for the coastal gill net, respectively. In recent, the distribution and centroid of fishing ground moved northward, as seawater temperature increased. The species spawned in the coastal areas of Gangwon, northern East Sea, during winter, started to move to deeper water after spawning from spring, extended widely from Gangwon to Ulsan, southern East Sea, during summer, and migrated back to the spawning ground off Gangwon during autumn.
