Fisheries in the EU-UK Trade and Cooperation Agreement (TCA) are provided for in Articles 493 to 511 TCA. This chapter highlights the fact that the TCA, whilst providing for no tariffs and charges (fiscal measures) on fisheries products moving between the two jurisdictions, has reintroduced new non-tariff (non-fiscal) measures on such movements when private parties are engaging in the export of fisheries to each other’s jurisdiction. For some, the TCA is the cod’s pollocks: short-term predictability for the fisheries industry was maintained by the TCA by suspending any changes to fisheries arrangements through the insertion of an adjustment period, applying until at least 2026. For others, the TCA could be considered a damp squid, given that post-2026, annual and multiannual negotiations will be introduced, which can amend various fishing opportunities concerning fishing quotas, stocks, and access to waters. This chapter provides an outline of the main fisheries provisions of the TCA, which adds to the EU’s growing repertoire of international agreements regulating fisheries.
