What does Cefas do?

We are the government’s marine and freshwater science experts. We help keep our seas, oceans and rivers healthy and productive and our seafood safe and sustainable by providing data and advice to the UK Government and our overseas partners. We are passionate about what we do because our work helps tackle the serious global problems of climate change, marine litter, over-fishing and pollution in support of the UK’s commitments to a better future (for example the UN Sustainable Development Goals and Defra’s 25 year Environment Plan).

We help keep our seas, oceans and rivers healthy and productive and our seafood safe and sustainable

We work in partnership with our colleagues in Defra and across UK government, and with international governments, business, maritime and fishing industry, non-governmental organisations, research institutes, universities, civil society and schools to collate and share knowledge.  Together we can understand and value our seas to secure a sustainable blue future for us all, and help create a greater place for living.
