Public money can be better spent to support sustainable fishing and the wellbeing of fishing communities

In 2020-22, almost two-thirds (65%) of government support to fisheries (as measured in the OECD Fisheries Support Estimate database) risked encouraging unsustainable fishing in the absence of sustainable fisheries management. Investments in assessing and ensuring fish stock health is beneficial for both a sustainable ocean economy and fishers’ livelihoods. But some support drives unsustainable fishing practices. The risk that this happens depends on two things: 

  • The type of support policy and how directly it affects fishing costs and benefits. . 

  • The condition of the fisheries benefiting from support – in particular, whether they are effectively managed, and whether there is scope for fishing the target stocks more intensively without compromising stock health.

Governments need to review their support policies to understand how they are affecting fishing costs and benefits, and whether they are encouraging over-capacity, over-fishing or illegal fishing. 

Improving the productivity and resilience of fisheries

Fisheries and aquaculture provide food for billions and employment for millions. But illegal fishing, overfishing and pollution are all endangering fish stocks and ecosystems. The OECD Review of Fisheries 2025 analyses the current state of fisheries and aquaculture, as well as policies covering 79% of global fish production in 2020-2022.

  • Climate change is one of the major issues facing the fisheries sector. Variations in ocean water temperatures and changes in currents and acidification as well as extreme weather events, have, and will increasingly have, significant impacts for fish stocks and the fishing industry in both the short and long term.

  • This note explores the issue of climate change mitigation in capture fisheries. At a global scale, fisheries’ greenhouse gas (GHG) emissions are estimated to account for around 4% of all emissions from food production and 0.5% of total emissions. Fuel use during fishing is estimated to account for between 60% and 90% of the sector’s emissions up to the point of landing.

  • Fisheries and aquaculture provide employment for millions and food for billions. They play key roles in global food security and the economies of coastal fishing communities. But climate change, illegal fishing, overfishing and pollution are all endangering fish stocks and ecosystems. The economic, social and environmental performance of the fisheries sector is dependent on sustainable management, smarter government spending and forward-thinking public policies.

  • The OECD has created a new legal instrument to fight illegal, unreported and unregulated fishing –helping governments to keep public money out of the hands of unscrupulous actors.
