Marine and freshwater fisheries

Defra is the UK custodian of the marine and aquatic environment, which is a shared and valuable asset.

Oceans and seas cover 70% of the world’s surface and are of critical importance economically, environmentally and socially. They are a valuable source of food, minerals and fossil energy; provide essential and biodiverse habitats; account for almost 50% of the world’s carbon fixing potential; and offer us opportunities to exploit renewable energy sources’ such as wind and tidal power.

Freshwater and migratory fish are valued and important aspects of our ecosystems. Safeguarding these stocks contributes towards Defra’s biodiversity objectives, as well as bringing significant socio-economic benefits.

Marine fisheries

Defra’s marine fisheries work is an integral part of our work to achieve clean, healthy, safe, productive and biologically diverse oceans and seas. Information on our work on marine fisheries is therefore included in our marine pages.

Defra works closely with the Environment Agency to conserve salmon, eels and freshwater fish to maintain biodiversity and economic and recreational opportunities provided by these fisheries in England and Wales.
