Their catch. Their data. Their decisions.

In Jomvu Kuu, a fisher community in Kenya, fishers are using catch data to understand what is happening in their fishery and shape what happens next.

 

Across Africa, declining fish stocks are already affecting fisher communities that depend on healthy fisheries. Fishing pressure and unsustainable fishing practices are contributing to these declines, threatening incomes and food security. In East Africa, studies show an estimated 70% of the region’s coral reefs have been fished below a sustainable level.

In Jomvu Kuu, a fisher community in Kenya’s port city of Mombasa, life is closely tied to fishing. The community includes small-scale fishers who harvest prawns, crabs and finfish, as well as fish traders and processors who depend on the daily catch for their livelihoods. Other businesses, including boat builders and net repairers, also support the local fishing economy. For many households, fishing is an important source of income and food.

       

“While everyone in this community is not a fisher, in many homes, one fisher often supports a family of seven or more people,” said Stephen Oluoch, a programme manager from Blue Ventures’ local partner, Community Integrated Development Initiative, Kenya (CIDI).

The Jomvu Kuu fishery is located on a channel and is known for its variety of prawns, including white, tiger, jumbo and queen prawns. However, years of fishing in the same inshore waters, alongside unsustainable fishing practices, are putting pressure on the fishery, with fishers reporting declines in both the abundance and size of their catch.

“This is where we all go to fish every day, as our fishing gear is not sophisticated enough to venture into the open ocean,”  said Msoma Kombo, a prawn fisherman.

Reflecting on the changes he has witnessed, Samuel Kairu, a fish trader, said, “Five years ago I used to take between 30 kilos to 100 kilos of shrimps to the market in a day. These days, the highest I take is between 5 kilos to 10 kilos.”

The decline in shrimp catches has affected the income of community members and is a sign of the wider changes affecting the fishery.

“We are now catching fish that cannot be sold in the market or eaten at home,” Kairu explained. “They are too small.”

Towards the end of last year, the Jomvu Kuu Beach Management Unit (BMU) began working with CIDI to strengthen fisheries management through community-led catch monitoring. After just three months of catch data collection, spanning from January to March 2026, the community convened a feedback meeting to review and validate the findings.

     

The data revealed a high proportion of juvenile fish in the catch, prompting discussion within the community about management measures to improve the fishery.

“From the collected catch data, we realised we may be destroying our own fishery,” said Tima Mwinyi, one of the BMU’s data collectors.

The findings also showed that, although many fishers use legal fishing gear, some continue to use illegal and destructive fishing methods, including mosquito nets and beach seines. Recognising the potential long-term impact on their resources and livelihoods, the community organised a follow-up meeting to discuss potential fisheries management strategies.

“Catch data collection has happened before in our BMU. However, we have never had the data brought back to us. This exercise has shown us how our activities are affecting the fish stock,” said Hamisi Kahindi, the BMU chairperson.

Using the evidence collected, BMU members identified several priority actions. These included promoting the use of sustainable fishing gear that targets mature fish, discouraging destructive methods such as mosquito nets, raising awareness among fishers about sustainable fishing practices, and exploring options such as seasonal fisheries closures or no-take zones to allow stocks to recover.

     

Any decision to introduce a fisheries closure would require extensive community dialogue, as well as consideration of alternative livelihood opportunities. 

“We are taking advantage of experiences in neighbouring BMUs to inform effective community engagements and participation not just within our BMU but also with our neighbours should the community endorse a seasonal closure or no-take zones,” said Kahindi.

The BMU also recognised the need to strengthen its governance framework. Members proposed reviewing and updating outdated bylaws to address illegal fishing through measures such as regulating access by unregistered fishers, strengthening enforcement, and introducing clear leadership term limits to facilitate regular elections and improve accountability.

With access to the data and an active role in collecting and reviewing it, community members are now turning what they have learned into ideas for improving their fishery.

“When communities understand the data, they are better positioned to identify solutions that will help restore their marine ecosystem and improve future catches,” said Oluoch.

For Jomvu Kuu, this is only the beginning. Over the coming months, the community will undertake participatory mapping to identify fishing grounds and potential areas for fisheries closures or no-take zones, conduct sensitisation meetings to promote sustainable fishing practices, engage community members and neighbouring BMUs in dialogue to build consensus around fisheries closures, and explore gear exchange programmes to phase out destructive fishing methods.

By acting on evidence, the Jomvu Kuu BMU is laying the foundation for healthier fisheries, improved livelihoods and more resilient coastal environments for both people and the ocean.

Cabo Verde

At least 6,000 fishers and 3,500 processors – mostly women – and sellers are active in the fisheries sector. Almost all artisanal-caught fish is sold and consumed locally, but fish from the distant-water industrial fleet accounts for 80% of exports from Cabo Verde.

BV works closely with the local NGO Fundaçao Maio Biodiversidade to support communities to use robust data to inform fisheries management and improve value chains. Our partnership has so far focussed on Maio island, but we have plans to scale this approach to at least five of the ten islands that make up the archipelago.

Unlike other countries in West Africa, there is no practice of community management in Cabo Verde, although there are a variety of community associations on the islands that represent fishers’ interests. BV is supporting partner organisations to strengthen the capacity of these groups to move towards the co-management of marine resources and the development of community-driven protected areas.

The Gambia

The Gambia’s coastline is only 80km long, but is home to a rich mangrove ecosystem that supports locally important fisheries. Sadly, much of the coastline has been devastated by sand and ilmenite mining, uncontrolled property development (including in protected areas), and a rapid ratcheting up of industrial fishing effort, largely to feed the country’s three fishmeal and fish oil factories.

Our approach in The Gambia is to empower local actors including CETAG and Gambian Environmental Alliance to raise their voices against these drivers of environmental destruction, and find community-led solutions. BV is also working with the well-respected youth and women groups SANYEPD and Hallahin Women Oyster Farmers to help communities secure preferential access to fish and shellfish.

Senegal

Fishing and the collection of shellfish is central to the lives of most coastal dwellers in Senegal, and seafood is part of almost every meal in the country. 

But massive overfishing by both industrial and artisanal fleets, as well as increasing exports of fishmeal for aquaculture, is threatening the way of life and food security in the country. As fish stocks dwindle, the staple National dish of Senegal “Thiebou Djeun” –  “Fish and Rice” – is becoming a luxury for many. 

Blue Ventures’ work in Senegal is focused mainly in the Sine-Saloum and Casamance deltas   of the country, home to hundreds of thousands of hectares of fish-rich mangroves. We have teamed up with Kawawana, Senegal’s oldest LMMA (known locally as APAC), to support the protection of 18,000 hectares of mangroves, and to help monitor and manage the rich fisheries they contain. Through our partners Nebeday and EcoRurale, we are also working with other communities, and especially women groups, to put in place community-based fisheries management systems, focusing particularly on the oyster and shellfish collection that are major sources of income in estuaries and deltas.

We’re new to Senegal but working to scale our communities-first approach to more partners and communities. We’re also aiming to build alliances with grassroots, national, regional and other like-minded organisations to advocate for better marine protection and to strengthen national inshore exclusion zones for small-scale fishers in which industrial fishing is restricted.

Guinea-Bissau

The West African country of Guinea-Bissau is home to the unique Bijagos archipelago, a network of some ninety mangrove-fringed offshore islands and extensive mudflats supporting large amounts of migratory bird species, as well as megafauna such as manatees, dolphins, and sea turtles. The Bijagos people continue to live a very traditional lifestyle, where the collection of marine invertebrates plays an important role in food security and cultural traditions. The country is also home to extensive mangrove-fringed river systems that support rich fisheries.

Blue Ventures has been working with Tiniguena, one of the oldest conservation groups in Guinea-Bissau, to support the establishment of the country’s first community-led MPA, in the Bijagos islands. Guinea-Bissau is a new venture for us, and we envision scaling to new partners and communities in the coming years. Our focus is on data-driven community-led management of fisheries, which are of enormous importance to coastal communities, in particular women.

Timor-Leste

Since 2016, our work in Timor-Leste has evolved into a dynamic movement supporting community-led marine management and coastal livelihood diversification in Asia’s newest country. From our origins on Atauro Island, considered to harbour the most diverse coral reefs on earth, we’re now working with numerous communities on the island and the mainland to help improve management of critical coral reefs and seagrass ecosystems.

We’re helping communities reinvigorate traditional community governance practices − known as Tara Bandu − to support marine conservation, in particular through the use of temporary and permanent fishing closures, and community-led monitoring of marine ecosystems and fisheries.

We’re helping communities come together to exchange their experiences of conservation across their shared coastline, building a new movement of local support for systems change in the management and conservation of Timor-Leste’s coastal waters.

Alongside our community conservation efforts, we have also pioneered Timor-Leste’s first homestay association, which has provided income from visiting ecotourists on Atauro Island.

Our team in Timor-Leste’s capital Dili works closely with government, civil society organisations and NGO partners.

Tanzania

Like its neighbours within the Northern Mozambique Channel marine biodiversity hotspot, Tanzania harbours some of the most diverse marine ecosystems in the Indian Ocean. These habitats are facing unprecedented challenges from overfishing and climate change. 

The Government supports the use of co-management to improve the management of marine resources, but a community’s ability to be meaningfully involved in this partnership approach is all too often hampered by the capacity of its institutions, to organise and to acquire the skills and resources they need. 

Our Tanzanian team has worked with communities and local organisations to support locally led marine conservation since 2016. Our work has expanded from Zanzibar to the mainland regions of Tanga, Lindi and Kilwa. Our technicians work with local partners to help communities strengthen co-management systems, through Beach Management Units (BMUs), Shehia Fishing Committees (SFCs), and Village Liaison Committees.

We have three types of partners in Tanzania: NGOs, CSOs and government. Our NGO implementing partners Mwambao Coastal Community Network, Sea Sense, and Jongowe Development Fund have spearheaded a remarkable acceleration in the uptake of community-based fisheries management and conservation in recent years, notably through the use of short-term fisheries closures to catalyse broader community conservation.

Our CSO partners include Kilwa BMU Network, NYAMANJISOPOJA CFMA and Songosongo BMU, while our government partners comprise the Ministry of Fisheries in Mainland Tanzania, and the Ministry of Fisheries in Zanzibar, as well as local government authorities in Pangani and Kilwa.

Following the conclusion of the SWIOFish project in 2021, we are also working with partners on an initiative to support the establishment and functioning of a fisheries co-management forum. The forum will facilitate engagement between national and local government authorities and NGOs involved in fisheries co-management initiatives along the Tanzania mainland coast, with the aim of enhancing networking and strengthening management and governance.

Somalia

With one of Africa’s longest coastlines, Somalia’s diverse marine environment supports enormously productive coastal and offshore fisheries.  Decades of conflict have undermined the country’s capacity for fisheries management, with many foreign industrial vessels fishing with impunity, and little regard for the critical importance of Somalia’s coastal fisheries for local livelihoods and food security.

A period of relative political and social stability unprecedented in recent decades is now presenting new opportunities to address past challenges, and to realise the considerable opportunities that well-managed coastal fisheries and conservation can offer Somalia. We are forging partnerships with community organisations in Somalia to build their capacity and skills to help coastal communities manage their fisheries for food security, livelihoods and conservation.

Philippines

The Philippines forms part of the ‘coral triangle’ epicentre of global marine biodiversity, with unparalleled diversity of marine species.  Over half of the country’s 107 million people live in rural areas, and approximately three quarters depend on agriculture or fisheries as their primary source of livelihoods.

Through our partnership with People and the Sea, we are supporting communities in the eastern Visayas to set up and utilise participatory data systems to monitor and understand the status of their fisheries, in a way that is meaningful for them. Through provision of access to strong data systems and training in data collection this year, these communities will soon have access to real time fisheries data and visualisations that will enable them to make informed decisions around the management of their fisheries.

Indonesia

Indonesia comprises almost 17,500 islands stretching across three time zones. This archipelagic nation has the 2nd longest coastline in the world − and the largest coastal fisheries resource − of any country on Earth. More than ninety per cent of Indonesia’s seafood production comes from small-scale fisheries, which are underpinned by the planet’s most biodiverse marine ecosystem, known as the Coral Triangle.

We have supported community-led marine conservation in Indonesia since 2016. Our team works in close partnership with 17 Indonesian organisations supporting community-based approaches to coral reef and mangrove conservation across 81 communities in fourteen provinces, collectively reaching over 80,000 people. 

Since 2019 we have brought these partners together within a peer learning network of Indonesian organisations specialised in supporting community-based marine conservation. The network is based on the shared values of the organisations, including a commitment to promote the rights of traditional fishing communities in conservation. Our support across these communities is customised to each context − the local fisheries, community stakeholders, seafood supply chains, legal frameworks and customary traditions governing fisheries management and conservation.

In Sumatra and Kalimantan we are strengthening our work in community conservation of globally important mangrove forests. We are supporting and strengthening community-forest management and supporting local partners who are adapting our catalytic model for temporary fishery closures to mangrove-dependent fisheries like mud crab.

We are working closely with our local partners Forkani, Yayasan LINI, Yapeka, Yayasan Planet Indonesia, Foneb, Komanangi, JARI, Ecosystem Impact, Yayasan Tananua Flores, Yayasan Baileo Maluku, AKAR, Japesda, Yayasan Citra Mandiri Mentawai, Yayasan Mitra Insani and Yayasan Hutan Biru, Yayasan Pesisir Lestari and Lembaga Partisipasi Pembangunan Masyarakat (LPPM) Ambon.

Kenya

Kenya’s coast supports an extraordinary diversity of tropical marine and coastal habitats.  These waters are threatened by a proliferation of destructive fishing practices and over-harvesting within the artisanal and commercial fishing sectors.

Our approach in Kenya focuses on strengthening Beach Management Units (BMUs) to improve fisheries management. Since 2016 our Mombasa-based technical team has provided support, mentoring and assistance to local partners including Coastal and Marine Resource Development (COMRED), the Lamu Marine Conservation Trust (LAMCOT), Bahari Hai, and Kwale Beach Management Unit Network (KCBN), a network of 23 BMUs in Kwale County

These partnerships have seen notable achievements in community-led fisheries management and conservation, including training and mentoring BMU leaders in eighteen communities in Kwale and Lamu Counties.

Belize

Belize’s marine environment encompasses some of the most diverse marine ecosystems in the Caribbean Sea, including vast coral reefs, mangrove forests and seagrass beds. We have maintained a permanent presence in Belize since 2010, supporting diverse fisheries and conservation efforts.

We work in close partnership with the Belize Fisheries Department, MPA managers, fishing cooperatives and fishers’ associations, and championed the establishment of a national scale domestic fishery targeting the invasive lionfish.  We are actively promoting community led fisheries management, building on the success of our pioneering work with management of invasive lionfish.

We’ve led a decade-long MPA monitoring and evaluation programme in Bacalar Chico Marine Reserve, and provide regular training in coral reef monitoring methods to MPA authorities across Belize, including helping establish management targets for Turneffe Atoll Marine Reserve, Belize’s largest MPA.

Our team supports and strengthens  fishing associations that advocate for the rights of their communities to be involved in decision making around access and use of coastal fisheries and to be key members of MPA management groups. Across the country we are working to ensure that fishers interests are mainstreamed in the design and implementation of marine conservation and fisheries management, improving the effectiveness of co-management of coral reef, mangrove and seagrass areas.

Madagascar

Blue Ventures’ journey began in Madagascar in 2003, and we’ve been supporting communities in marine conservation across the country ever since. We have five regional field programmes along Madagascar’s west coast, as well as regional offices in the towns of Ambanja, Mahajanga, Morondava and Toliara. Our national headquarters is located in the capital Antananarivo.

Across all these sites we support communities with the establishment of locally managed marine areas (LMMAs), and work with government partners to secure national recognition for community conservation initiatives. First developed in Madagascar by Blue Ventures in 2006, the LMMA concept has since been replicated by communities at hundreds of sites over thousands of kilometres of coastline, now covering almost one fifth of Madagascar’s inshore seabed. Our research in Madagascar has demonstrated globally important evidence of the benefits of LMMAs to fisheries and conservation.

Our work focuses on strengthening community institutions in marine management and governance, and pioneering new approaches to catalyse community engagement in ocean conservation. These innovations have included establishing community led ecological monitoring and the country’s first mangrove blue carbon project.

At the national level, we partner with the LMMA network MIHARI, which brings together 25 partner conservation organisations supporting 219 LMMA sites across the country. Our policy team is also actively involved in advocating for more robust legislation to safeguard the rights and interests of fishing communities, and to remove destructive industrial fishing from coastal waters. In 2022 we supported the launch of Fitsinjo, an industrial fisheries watchdog organisation. The network highlights industrial fishing and IUU activities in Madagascar and the broader Western Indian Ocean region.

Given the lack of basic services in remote coastal regions in Madagascar, we also help communities access basic healthcare through training and supporting women to serve as community health workers. We do not replace government health systems, but work to strengthen existing structures in close collaboration with government health actors and specialist NGOs. We also incubate Madagascar’s national health-environment network, which brings together 40 partner organisations to address the health needs of communities living in areas of conservation importance across the country.
