Condition of Octopus Fishery Resources with Ecosystem Approach to Fisheries Managament Assessment on Langkai and Lanjukang Islands, Makassar City

The octopus is a type of fishery commodity with significant economic value in both local and domestic markets. The rise of irresponsible octopus fishing activities, particularly in the waters of the Spermonde Archipelago, has become a growing concern. Sustainable management of octopus fisheries is necessary to prevent the exploitation of resources. The areas surrounding Langkai and Lanjukang Islands exhibit high potential for octopus populations. However, the productivity and catch status of octopus fisheries require in-depth research, as there is a lack of relevant data. This study aimed to assess the status of octopus resources around Langkai and Lanjukang Islands. The research was conducted from January to March 2023 using field surveys and observation methods. Primary data were collected through direct observation of octopus fishing units and interviews with fishermen and octopus collectors on the islands. Respondents were selected using purposive sampling, focusing on active octopus fishermen. Secondary data were obtained from the South Sulawesi Agency of Marine Affairs and Fisheries. Data analysis was performed using flag modeling with several indicators in the octopus resource domain. The results indicate the following scores for each indicator: standard CPUE (0.8, medium), octopus weight trend (0.5, medium), proportion of juveniles caught (0.45, high), catch composition (0.15, high), octopus collapse range (0.2, medium), and ETP (endangered, threatened, and protected) species (0.15, high). These findings suggest that the condition of octopus fishery resources in the waters around Langkai and Lanjukang Islands is classified as moderate (yellow level), with an aggregate score of 2.25.
