Fisheries and Aquaculture - Towards sustainable development of fishing and aquaculture activities
“To develop an ecosystem-based holistic approach to fishery management by assessing non-fishery influences.”

The problem

Traditional single-species fishery management has failed, partly because individual species are not isolated, but are integral part of the wider ecosystem. To overcome this shortcoming involves improving the responsiveness of European fishery management to the anthropogenic and natural factors affecting exploited populations. A holistic, ecosystem approach would help to assess the effects of a range of factors on the biological cycle of exploited stocks and the ecosystem that supports them.

IN EX FISH  Incorporating non-fishery influences into stock assessments


IN EX FISH aims to increase the responsiveness of fishery management to a range of anthropogenic and natural factors through a review of fish stock dynamics in four European sea areas: the North Sea, the Baltic Sea, the West Iberian Sea and the Mediterranean Sea. It has four objectives:

  • To review the effects of anthropogenic and natural factors on the dynamics of fish stocks
  • To develop a framework for evaluating anthropogenic and natural factors on the dynamics of exploited
    fish species
  • To review indicators of ecosystem status and identify effective ones
  • To demonstrate the effect of integrating the IN EX FISH knowledge into fishery management

Contribution to policy development:

  • IN EX FISH will improve the scientific understanding and robustness of advice presented to the EU and its institutions by ICES (International Council for the Exploration of the Sea) and GFCM (General Fisheries Council for the Mediterranean)
  • The development of eco-status indicators and management tools incorporating them into fishery management will contribute to the ongoing reform of the CFP and developing sustainable European fisheries
  • Advice based on an ecosystem approach to fishery assessment will enable the EU and Member States to make better informed decisions for future fishery management
