Modeling the Contribution of Traditional Sero Fisheries to Blue Economy Goals: Evidence from Rural Indonesia

Abstract

This study examines the integration of traditional sero (staked weir) fisheries in Bone Regency, Indonesia, into the sustainable governance and blue economy frameworks. Despite their socio-cultural importance, these small-scale fisheries remain undervalued in policy discourse and local management plans. This research utilizes Structural Equation Modelling (SEM) to assess fishers’ perspectives and the factors driving regulatory compliance across six latent variables: economic characteristics, fishing techniques, social aspects, institutional dynamics, policy knowledge, and compliance behavior. The measurement model was empirically distinct, with all Heterotrait-Monotrait Ratio (HTMT) values below the 0.85 threshold. Key findings indicate that Policy Knowledge (C) has the most potent positive effect on compliance, with β = 0.902. Additionally, Livelihood Resilience (B) significantly affects compliance (β = 0.760), whereas Socioeconomic Characteristics (X) have a substantial adverse direct effect (β =1.003). Together, these variables explain a significant proportion of the variance in compliance behavior, with an R2 of 0.915. The results indicate that higher income, institutional trust, and strong community ties enhance compliance by enabling fishers to adopt sustainable practices. Conversely, economic instability hinders the application of policy knowledge. The study concludes that involving fishers in organizations and strengthening institutional support are vital for aligning artisanal practices with the blue economy. Implementing coastal spatial planning and adaptive interventions will help balance ecological preservation with the economic well-being of coastal communities.
