The state of the world’s fisheries: Six takeaways
Current research
Managing impacts on vulnerable species
What drives fishery improvements?
Climate change
Completed research
Socioeconomic impacts
Understanding impacts of MSC certification, such as market access and retention, and gaining trust.

Funding research
Over £5.25 million has been dedicated to 144 fisheries and research projects around the world through our Ocean Stewardship Fund.
In 2024, almost £1 million was awarded to research projects that will safeguard fish stocks and minimise fisheries’ impacts on wildlife.
