In this study, we conducted a study on catch characteristics such as the total amount of catch and the catch per unit effort in the coastal area of Jeollanam-do Province for the sake of effective fisheries management of Octopus minor. The Gamak·Yeosa Bay were the only area characterized by high number of individuals, amount of catch and catch per unit effort through 2017 to 2018. On the other hand, Sinan coastal area was the lowest. Monthly number of individuals was high in February 2017 and January 2018. Monthly amount of catch per unit effort was high in January-March 2017 and January-February 2018. Monthly amount of money per unit effort differed from coastal areas to bays. The ratio of local immature of Octopus minor was the highest at Gangjin with 80.7% and the lowest at Jangheung with 50.9%. The ratio of monthly immature of Octopus minor was the highest at 91.3% in August and the lowest at 41% in July.
