Abstract

Fisheries resource assessment is pivotal for grasping marine ecosystem dynamics and guiding sustainable management practices. This study focuses on exploring the fisheries resources within Berau Bay, situated in the biodiverse-rich West Papua Province, known for its significant marine biodiversity and importance to local livelihoods. Despite its importance, there is a notable absence of comprehensive assessments concerning the bay’s fisheries resources and their utilization potential. This research endeavors to fill this gap by providing a detailed analysis to inform sustainable management strategies. Our findings reveal a diverse range of fish families dominating Berau Bay, with significant contributions from Carangidae and Scombridae. Moreover, acoustic surveys uncover substantial Fisheries Resource Potential (FRP) across three zones: Zone 1 at 501.555 tons, Zone 2 at 854.634 tons, and Zone 3, primarily designated as a conservation area, at 678.188 tons. The cumulative FRP potential amounts to 2.034.377 tons, encompassing various species categories, with an estimated annual utilization rate of around 1.627.502 tons. These results challenge previous assumptions regarding the bay’s fisheries composition and potential, emphasizing the necessity of updated assessments. Additionally, they enhance our understanding of the region’s marine biodiversity, underscoring the urgency of targeted conservation efforts for sustainable resource management. This study emphasizes the significance of holistic approaches to fisheries management, integrating ecological, socioeconomic, and conservation considerations. Such interdisciplinary efforts are paramount for safeguarding marine ecosystems and supporting the livelihoods of coastal communities worldwide.
