How do ICES scientists count all the fish in the sea?

Let a newly published brochure explain it for you.
Published: 18 June 2014

‚ÄčIt is, of course, impossible for scientists to count every single fish in the sea. Instead, they collect as much information as they can from three main sources: landings at ports, fishers, and research vessels surveys.

The collected data is then used to estimate the size of commercial fish populations such as cod, haddock, and hake, and the estimates are used by ICES to give advice to international commissions and governments on the sustainable exploitation of these fish populations.

Our newly published brochure "Fish stocks: counting the uncountable?" explains how fish stocks are assessed in the Northeast Atlantic and gives insight into the types of science and information that goes into scientists' stock estimates. It also describes the ICES advisory process and sheds light on the efforts in integrating ecosystem considerations into fisheries advice.
