COBEC’s marine research programme structure covers marine environment, marine biodiversity and marine fisheries. The programme focuses on understanding the impact that pressures have on the state of the marine environment, assessing whether the impact is of significance, and evaluating alternative management strategies. It also integrates a sustainable marine fisheries research with the wider marine research. The marine fisheries research assists managers in restoring and maintaining healthy fish stocks; adopting an ecosystem-based approach to fisheries management; and promoting marine biodiversity conservation.
