^ Total advised catch in 2026 relative to the EU–UK agreed catch limit approach for 2025 (2970 tonnes). This limit reflects the sum of the EU–UK agreed TACs in 2025 (2953 tonnes), divided by 0.9945 to account for a 0.55% deduction for third-country catches, following the method for projecting third-country catches (EU–UK Joint Committee, 2023).
