초록

본 연구는 2003년 3월부터 2004년 4월까지 강원도 연안에서 유자망어업에서 어획된 대구횟대를 매월 채집하여 성숙과 산란에 관하여 조사한 것이다. 대구횟대의 산란기는 생식소성숙도지수, 난경 등의 월별 변화에 의한 결과 12월에서 이듬해 2월로 추정되어졌다. 체장과 포란수와의 관계는 $F=285.11TL^{1.4092}$ ($R^2$=0.571)이었으며 체중과 포란수와의 관계는 $F=1.449.8BW^{0.5514}$ ($R^2$=0.577)이었으며, 포란수는 어체가 커질수록 증가하였다. 최소포란수로 8.814립 (TL: 14.7 cm), 최대포란수는 28,560립 (TL: 24.4 cm)이었다. 최소성숙체장은 15 cm였으며, 이때의 나이는 약 2세였다. 체장계급별 성비는 소형어에서는 수컷이 약간 우세하였으나 24 cm 이상에서는 암컷이 90%로 높게 나타났다.

We investigated the maturity and spawning of black edged sculpin, Gymnocanthus herzensteini caught by gillnet in the East Sea from March 2003 to February, 2004. We analyzed monthly changes in maturity stages, gonadosomatic index (GSI), gonad weight (GW), egg diameter, fecundity, total length at 50% group maturity and sex ratio. The spawning period was December to February. The fecundity ranged form 8,814 eggs at 14.7 cm (TL) to 25,560 eggs at 24.4 cm (TL). The relationship between total length (TL) and fecundity (F) was $F=285.11TL^{1.4092}$ ($R^2$ =0.571) and fecundity increased with total length. The total length at 50% group maturity was estimated to be 15.25 cm. The sex ratio was 60 for female and 40 for male, where the female population was seen to be slightly predominant. For sex ratio by length class, male was a little predominant in small size, but female was 90% more than 24 cm.
