Abstract

The common octopus, Octopus vulgaris is commercially important species in Korea. Korean fishing vessels have actively caught it. However, the study of this species has been poorly known. Therefore, the purpose of this study is to provide information about maturation and spawning period of this species. Samplings have been monthly collected in Tongyoung and Sacheon of Gyeongsangnam-do, using traps. A total of 748 individuals were sampled from February 2007 to January 2008. We analyzed monthly changes in maturity stages, gonadosomatic index, total weight at 50% group maturity. The octopus total weight was between 128.6 and 3381.4 g. Females were distributed between 129.8 and 3381.4 g and males between 128.6 and 2378.4 g. The spawning periods were May to June and September. The total weight at 50% group maturity was estimated to be 919.6 g.

이 연구는 경남 통영과 사천지역의 연안에서 2007년 2월부터 2008년 1월까지 연안통발어업에 의해 어획된 참문어를 매월 1회 채집하여 성숙과 산란에 관한 연구를 수행하였다. 조직학적 검경을 통한 생식소 성숙도의 월별 발달과정을 분석한 결과 암컷의 경우, 조사 기간 중 미숙, 중숙, 성숙, 완숙기의 개체들이 혼재하여 출현하였으며 산란이 가능한 완숙 개체는 10월과 12월을 제외하고 연중 관찰되었다. 수컷의 경우도 조사기간 중 미숙, 중숙, 성숙, 완숙기의 개체들이 혼재하여 출현하였으며 방정이 가능한 성숙 이상의 개체는 전 기간에 걸쳐 관찰되었다. 생식소 중량지수의 월 변화는 암컷의 경우, 2월 1.26에서 5월 4.84로 증가하다 이후 감소하였으며 8,9월에 다시 상승하였다가 10월에 0.38의 낮은 값으로 감소하였다. 이러한 생식소 성숙도의 월별발달과정과 생식소 중량지수의 월변화를 바탕으로 참문어의 산란기를 추정한 결과 주 산란기는 9월로 나타났다. 수컷의 경우는 연중 1.5이상의 높은 값을 나타냈다. 참문어의 50% 군 성숙체중은 919.6 g로 추정되었다.
