Mismanagement Issues in Sustaining Capture Fisheries in Lake Batur

Lake Batur holds significant aquatic value and has been prioritized nationally for developing Indonesia's aquaculture operations and economic growth. This initiative has transformed traditional fisheries into industrial aquaculture, significantly impacting both the ecological and socioeconomic status of the lake area. The catch per trip and income of fishermen in 2022 decreased by 7% and 11% compared to the previous five years, respectively. Through diverse research methods including surveys, field observations, and in-depth interviews, we identified several key findings that highlight the necessity for implementing appropriate regulations to improve Lake Batur's management practices. These findings include: (i) declining performance of current fisheries, (ii) concerns about the long-term sustainability of aquaculture, and (iii) inadequate management approaches. Therefore, policies should prioritize preserving sustainable fisheries industries to support local socioeconomic well-being while safeguarding the lake's ecological integrity. Recommendations include setting limits on catch rates and revising spatial zoning to maximize resource utilization. Additionally, supporting policies should enable some fishermen to transition away from fishing activities, thus easing pressure on the lake's natural resources. The findings of this research provide broader implications, emphasizing the crucial importance of thoroughly considering all technical and social impacts of any policy to achieve an effective balance between economic growth and ecological sustainability.
