We are Cefas, the Centre for Environment, Fisheries, and Aquaculture Science. We are an agency of Defra (the Government’s Department of Environment, Food and Rural Affairs) and world leading experts in marine and freshwater science. We help keep our seas, oceans and rivers healthy and productive and our seafood safe and sustainable, by providing data and advice to Government and our overseas partners.

We are passionate about the work we do because we are committed to making a difference to the health of our planet and the people that depend on it. Our work helps tackle the serious global problems of climate change, biodiversity loss and food security, in support of the UK’s commitments to a better future (for example, UN Sustainable Development Goals, net zero by 2050, and Defra’s 25-year Environment Plan and Food Strategy).
