본 연구는 경남 통영과 사천지역의 연안에서 2007년 2월부터 2008년 1월까지 매월 1회 연안통발어업에 의해 채집된 참문어를 대상으로 참문어의 성숙과 산란에 관하여 조사하였다. 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. 난소의 성숙발달에 따른 난경크기 변화를 알아보기 위해 난소 내 난경조성의 월 변화를 조사한 결과 9월에 1.1-1.2 mm로 최고값을 나타냈다. 암수의 비율은 약 0.48:0.52로 나타났지만 암수의 성비(1:1)에 대한 유의한 차는 없었다(p > 0.05).
Samplings have been monthly collected in Tongyeong 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 and sex ratio. Mean biomass (total wet weight) of the female specimens ranged from 129.8 to 3,381.4 g and that of the male specimens ranged from 128.6 and 2,378.4 g. The spawning periods were May to June and September. The fecundity ranged from 5,715 eggs at 252.0 g to 240,990 eggs at 3,381.4 g of total wet weight. The relationship between total wet weight (TW) and fecundity (F) was F = 26.539 TW1.1548 (r2 = 0.8199) and fecundity increased with total wet weight. Sex ratio was not significantly different from the 1:1 (p > 0.05).
