^ Total advised catch in 2027 relative to the EU–UK agreed catch limit approach for 2026 (3086 tonnes). This limit reflects the sum of the EU–UK agreed TACs in 2026 (3069 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).
