The Octopus cyanea fishery in the Sawu Sea contributes the biggest octopus production in Indonesia, not only for the local market but also for the international market that needs ecolabel certification. However, there is still insufficient information, especially about the impact of fishing and the ecosystem. This research studies the stock status of Octopus cyanea using the depletion model and the spawning potential ratio model to give information about octopus fishing for ecolabel certification purposes. The results showed that the depletion model indicated the initial stock was 3,225kg and the catchability coefficient was 0.0022, which means the fishing gear used has low efficiency. The remaining stock was 47%, indicating that octopus fishery in Sawu Sea is in moderate status. The stock status, based on the spawning potential ratio (SPR) model, was recorded at 14%, which means an over-exploited status. The results reveal contrasting exploitation indicators. The exploitation rate (E = 0.45) indicates moderate exploitation, whereas the SPR value (14%) suggests over exploitation from a reproductive perspective. This discrepancy implies that overall fishing pressure is relatively low in terms of biomass removal but disproportionately affects immature individuals before they reach reproductive maturity. These findings underscore the importance of implementing size-based regulations and selective fishing practices to enhance reproductive sustainability and strengthen the fishery’s eligibility for ecolabel certification. © 2026, Egyptian Society for the Development of Fisheries and Human Health.
