Banggai Laut Regency is one of the largest octopus producers in Central Sulawesi Province. The potential of octopus resources in these waters is estimated at 10,652 ton/year. This potency has a close correlation with production. However, there has been a decrease in octopus production, indicating that the utilization rate in these areas has already overexploited. This study aims to determine the status or current utilization level of the octopus fishing ground. The status of octopus fishing ground in Banggai Laut waters was analyzed using Length Based-Spawning Potential Ratio measured by mantle length of captured octopus. The result of Spawning Potential Ratio analysis showed that its value was 15%, which is below the biological reference point (<20%). This value indicates that the utilization rate of octopus fishing ground in Banggai Laut Regency area has already overexploited. The countermeasures which can be used for the restoration and improvement of octopus stocks are necessary for the sustainability of octopus fishery in the future. © Published under licence by IOP Publishing Ltd.
