Abstract

The southwest coast of Madagascar is home to small-scale Coral Reef Fisheries (CRFs), a vital activity for livelihoods and the local economy of the fishermen community. Understanding all about the components of this CRFs, the nature of their interactions and the resulting outcomes is crucial for designing policies that promote equitable and sustainable fisheries. This research aims to apply the Social-Ecological Systems (SES) framework and network analysis to assess the SES structure and the characteristics of Ranobe Bay CRFs, Madagascar. This research was carried out from September to October 2024, requiring primary data from field observations, interviews with respondents, and secondary data from literature studies. The Socio-Ecological Network Analysis (SENA) was used to analyze the connectivity of the CRFs in this region. The research findings of the SENA results showed that this fishery is heavily centered around the fishermen's community: the Masikoro and the Vezo as the main actors of this activity. Nevertheless, according to the cluster value analysis, the findings highlight a high number of clusters showcasing a low connectivity and less compact SES structure. Ranobe Bay's CRFs' sustainability depends on fishermen's central connectivity within the network, which can be strengthened through improved policies and management to ensure effective governance.

Abstract

The Sawu Sea National Park (SSNP) is a critical marine conservation area that supports the sustainability of fish resources and the livelihoods of coastal communities in Rote Ndao Regency. This study aims to analyze the dynamics of fish resource utilization in the Traditional Sustainable Fisheries (TSF) sub-zone, examine actor networks and catch distribution, and identify potential conflicts and strategic issues in small-scale fisheries management. A mixed-methods approach was applied, including a quantitative survey, in-depth interviews, field observations, and spatial analysis using GIS. The findings reveal the presence of external fishers utilizing modern fishing gear within the TSF sub-zone, leading to increased exploitation pressure and rising conflict potential. Declines in CPUE, fish size, and the disappearance of particular species are early signs of overfishing. Overlapping fishing grounds among fleets exacerbate social tensions and threaten ecological sustainability. Strategic recommendations include enhanced monitoring, evidence-based adaptive zoning, participatory conflict resolution, habitat restoration, and incentives for eco-friendly fisheries. This study underscores the importance of participatory and collaborative governance approaches to ensure the sustainability of fish resources in conservation areas.
