Against this backdrop, Tanzania has moved to rein in industrial involvement in fishing on Lake Victoria, marking a significant policy shift aimed at safeguarding fish stocks, protecting small-scale livelihoods and restoring ecological balance in one of the world’s most important freshwater systems.

The announcement was made during a recent visit to Tanzania’s Kagera region by the Minister for Livestock and Fisheries, Bashiru Ally, who stated that industrial operators will no longer be permitted to engage directly in fishing activities on the lake. The decision follows years of concern among scientists, policymakers and fishing communities that unchecked commercial practices are accelerating the depletion of fish populations.

“Industrial encroachment, particularly by operators linked to fish processing and export, has increasingly undermined traditional fishing systems,” Ally said. “Urgent action is required to protect Lake Victoria for the survival and livelihoods of millions of people in the region.”

A regional lifeline under strain

Lake Victoria is far more than a shared body of water. Covering nearly 69,000 square kilometres, it is the world’s second-largest freshwater lake by surface area and is shared by Tanzania, Kenya, Uganda, Rwanda and Burundi. Tanzania controls just over half of the lake’s surface, making it the largest custodian of this critical regional resource.

The lake supports the livelihoods of more than 47 million people through fishing, processing, transport and trade. It also supplies water for domestic use, irrigation and industry, generates hydroelectric power downstream, and plays a central role in regional climate regulation and biodiversity conservation.

Economically, Lake Victoria hosts one of the most productive freshwater fisheries in the world, yielding an estimated 1.5 million tonnes of fish annually. Species such as Nile perch, tilapia and dagaa underpin an export industry valued at more than $1bn a year, supplying markets in Europe, Asia and the Middle East.

Yet this productivity masks growing vulnerability. Environmental experts warn that a combination of overfishing, pollution, habitat destruction and climate change has steadily eroded the lake’s ecological resilience.

Industrial pressure and ecological decline

Overfishing remains among the most visible threats. The widespread use of illegal gear, including undersized nets that capture juvenile fish, has reduced the reproductive capacity of key species. Industrial-scale operations, often better financed and technologically equipped than artisanal fishers, have been accused of harvesting fish faster than natural systems can replenish them.

At the same time, environmental degradation across the lake’s catchment has intensified pressure on the ecosystem. Wetlands that once acted as natural filters have been cleared for agriculture, settlement and industrial development. Their loss has increased nutrient runoff into the lake, fuelling algal blooms that deplete oxygen and threaten aquatic life.

Deforestation in surrounding river basins has compounded the problem, accelerating soil erosion and sedimentation, while rapid urbanisation has led to the discharge of untreated sewage and industrial effluent into the lake.

The cumulative effect has weakened Lake Victoria’s capacity to recover, raising fears of long-term ecological damage if corrective measures are not enforced.

Protecting livelihoods alongside conservation

Tanzania’s decision to restrict industrial fishing is framed not only as an environmental intervention, but also as a social one. Small-scale fishermen, operating from thousands of landing sites along the lake’s shoreline, have increasingly struggled to compete with larger operators.

By limiting direct industrial participation in fishing, authorities aim to restore balance, ensuring that artisanal fishermen, many of whom rely on the lake for subsistence as well as income, are not displaced from their traditional livelihoods.

The government has stressed that the policy does not target fish processing itself, which remains a major employer and export earner. Instead, processing companies will be required to source fish through regulated, legal supply chains rather than operating fishing fleets of their own.

Enforcement of existing regulations is also set to be strengthened, including protection of the legally mandated 200-metre shoreline buffer zone and tougher penalties for illegal gear. Officials say this will involve closer monitoring and greater collaboration with local fishing communities.

Regional cooperation and technology-led oversight

Lake Victoria’s challenges extend beyond national borders, making regional coordination essential. Tanzania has pledged to work closely with neighbouring countries under the framework of the East African Community and the Lake Victoria Basin Commission, which coordinates joint conservation and development efforts.

In 2025, EAC member states reaffirmed their commitment to sustainable management of the basin, pledging closer cooperation on climate adaptation, pollution control and fisheries governance.

Tanzania is also backing its conservation agenda with significant investment. Several multi-million-dollar initiatives are under way, including a regional study launched in collaboration with the Lake Victoria Basin Commission that uses satellite and Earth observation technology to monitor water quality, algal blooms and changes in lake volume.

In addition, the government plans to establish 10 monitoring and rescue centres across the lake at a cost of approximately 4.2bn Tanzanian shillings. These facilities are expected to improve surveillance, enhance safety for fishermen and strengthen emergency response as extreme weather events become more frequent.

Ultimately, the future of Lake Victoria hinges on finding a sustainable balance between economic activity and environmental stewardship, between regional integration and national responsibility, and between present needs and future security.

The move to curb industrial fishing signals a recognition that the lake’s resources are finite and that protecting them is essential to long-term prosperity. Its success, however, will depend on consistent enforcement and effective regional cooperation.

For now, as fishermen haul in their nets under a rising sun, the message from Tanzania’s shores is clear: safeguarding one of Africa’s greatest natural assets has become an urgent priority, not just for today, but for generations to come.

Notes to Editors

• Tanzania has banned direct industrial fishing activities on Lake Victoria, as announced by the Minister for Livestock and Fisheries, Bashiru Ally, during an official visit to the Kagera region.
• The policy aims to curb overfishing, protect fish stocks, safeguard artisanal fishing livelihoods, and restore ecological balance in Lake Victoria.
• The restriction targets industrial operators engaging directly in fishing, not fish processing. Processing companies must source fish through regulated and legal supply chains.
