Copenhagen: The annual fishing quotas for the Baltic Sea have once again been agreed under conditions of substantial pressure on stocks, and the underlying biological trajectory of several species shows little improvement. Eastern Baltic cod, which sustained one of Europe’s most economically significant fisheries for decades, remains in a state that scientific advice describes as severely depleted. Western Baltic cod is in a comparable condition. The advice from the International Council for the Exploration of the Sea has for several consecutive years been for closures of directed fisheries on these stocks, and the political decisions taken at the Fisheries Council have followed that advice in substance though with carve-outs for bycatch and small-scale fishers.
The collapse of Baltic cod has been an ecological event of considerable significance, and the policy response has accumulated lessons that are likely to inform other regional fisheries. The primary diagnostic factors are environmental rather than overfishing alone. Oxygen depletion in deeper waters, elevated water temperatures and changes in prey availability have created conditions in which the population cannot reproduce at rates sufficient to sustain commercial extraction. The Common Fisheries Policy provides instruments for managing fishing pressure but has limited reach over the underlying environmental drivers, which are addressed through the Marine Strategy Framework Directive, agricultural nutrient regulation and broader climate policy.
The economic consequences for coastal communities have been severe. Fishing fleets in Bornholm, the Polish coast, the Lithuanian coast and parts of Sweden have shrunk, with vessel decommissioning schemes supported under the European Maritime, Fisheries and Aquaculture Fund. The fund has been used to facilitate exit and to support diversification, but the social fabric of fishing villages depends on more than financial compensation. The cultural dimension of fishing communities is not easily reconstituted once vessels and crews are dispersed.
Denmark’s position in the Baltic debate reflects its dual interest as a fishing nation with substantial pelagic catches and as an environmental advocate with a strong record on marine protected areas and habitat restoration. Danish fisheries managers have been active in developing the regional management plans that allocate effort across multiple stocks and in advocating for ecosystem-based approaches that consider the interaction of species and their environment.
A broader question now sits over European fisheries policy. The Common Fisheries Policy was designed around the idea of maximum sustainable yield as the management objective for each stock. The conceptual framework remains valuable but is incomplete when ecosystems are changing rapidly under climate and pollution pressures. Several stocks have shifted in distribution, with Atlantic herring moving northward and warm-water species appearing in waters where they were previously rare. The management instruments must adapt to these changes, and the regional management plans provide some flexibility but their amendment is administratively slow.
The relationship with third countries adds another layer. The post-Brexit arrangement with the United Kingdom requires annual negotiation of shared stocks, with detailed scientific input but with political tensions over allocation and access. The Norway-EU arrangement is older and more stable but also depends on continuous scientific dialogue. The Atlantic-wide stocks managed through the North-East Atlantic Fisheries Commission show that international cooperation can produce results, but the negotiations are difficult and the conservation outcomes mixed.
The next reform cycle of the Common Fisheries Policy is approaching, and the diagnostic from the Baltic experience is one that will need to be reflected in the proposals. Sustainable fisheries cannot be managed as a single sector independent of environmental policy, and the architecture of regulation must reflect that interdependence rather than working against it.
