Abstract | This study aims to evaluate the reproductive potentiality of Octopus vulgaris to provide basic reproductive information for the management of biological resources. Samples were collected from May 2022 to September 2023 using octopus pots and drum-shaped nets in Yeosu and Wando, with a total of 1,821 individuals ranging in total weight from 64.5 to 1,598.5 g. The sex ratio (F:M) was 1:0.82 (n=1,001:820, 55.0% female), indicating a significantly higher proportion of females (p<0.05). The 50% maturity total weight in females was 169.3 g. In females, absolute fecundity was 116,602.7 eggs per individual, which was positively correlated with total weight. Relative fecundity was analyzed to be 123.8 eggs per gram in total weight. In males, the absolute fecundity was 123.9 spermatophores per individual, and the relative fecundity was 0.23 spermatophores per gram in total weight. The results of this study are expected to be used in estimating the amount of octopus resources in the future. 본 연구는 참문어 Octopus vulgaris의 생식잠재력을 평가하여 생물자원 관리를 위한 정보를 제공하고자 하였다. 시료는 2022년 5월부터 2023년 9월까지 여수 및 완도 인근 해역에서 문어단지 및 통발을 이용하여 전중 64.5-1,598.5 g의 1,821개체를 채집하였다. 성비(암:수)는 1:0.82 (n=1,001:820, 암컷 55.0%)로 암컷의 비율이 유의하게 높았다. 암컷에서 50% 군성숙 크기는 전중 169.3 g이었다. 암컷의 절대포란수는 평균 116,602.7개로 전중과의 상관관계가 있었으며, 상대포란수는 전중 g당 123.8개로 분석되었다. 수컷의 절대정포수는 평균 123.9개였으며, 상대정포수는 전중 g당 0.23개로 나타났다. 본 연구 결과는 추후 참문어의 자원량 추정에 사용될 것으로 판단된다. |
