Blue Ventures (BV) is a marine conservation organization that rebuilds tropical fisheries with coastal communities. By supporting Indigenous practices of small-scale fishers(SSF), BV helps address overfishing, habitat destruction, and climate change impacts. Its approach leverages traditional governance systems like Sasi (Indonesia), Tara bandu (Timor Leste), and Dina (Madagascar) to promote sustainable fisheries management. By 2030, BV aims to support 5 million people and protect 200,000 km² of high-biodiversity coastal seas.

BV's model integrates four key pillars: securing fishers' rights, community-led fisheries management, financial inclusion, and food security. Its data-driven approach empowers communities to monitor fish stocks in near real-time, improving decision-making and sustainability. BV’s pathway to scale focuses on supporting local partner organizations in leading lasting change. The organization currently provides £3.8 million in subgrants to over 50 local NGOs and CBOs in 10 countries, with plans to scale support to 400 partners across 20 countries by 2030.

BV pioneers locally managed marine areas (LMMAs), empowering communities to take ownership of their coastal resources. As an enabling organisation, Blue Ventures operates through three pathways to impact: it finds and funds local organizations that possess the presence, proximity, and permanence necessary to work with communities in establishing legal and functional LMMAs; it provides ongoing support to enhance their skills while catalyzing, iterating, expanding, and sustaining these efforts; and it amplifies the voices of SSF and customary law communities at national and global levels to ensure their priorities are acknowledged.

BV’s initiatives include all-women fisheries monitoring groups, learning exchanges, and leadership training to enhance community capacity. In Madagascar, BV has helped establish a national LMMA network (MIHARI) representing over 200 communities. Its gender-inclusive approach ensures that women play a key role in fisheries decision-making, strengthening conservation efforts and local livelihoods and helping preserve Indigenous peoples' cultural identity and heritage.

BV actively advocates for small-scale fishers' rights in global conservation policies, contributing to the post-2020 Global Biodiversity Framework, a global roadmap to halt and reverse biodiversity loss by 2030. BV founded and hosts the Transform Bottom Trawling Coalition, now a 100-member network working to reduce bottom trawling’s impact. BV collaborates with various partners, including the ICCA Consortium, to amplify Indigenous and small-scale fishers’ voices in policy discussions. Its advocacy efforts have influenced national fisheries policies, including Thailand’s commitment to phase out bottom trawling.
