Omissions
The quota loss was not a random consequence of Brexit but the result of the EU-UK Trade and Cooperation Agreement, which reallocated quota shares according to zonal attachment, with Ireland transferring roughly 15% of its quota value in UK waters.
The decommissioning of Irish boats was funded largely through the EU's Brexit Adjustment Reserve, i.e., EU compensation for Brexit losses.
The most recent data (Dáil Éireann debate, 22 October 2025) shows continued Brexit-linked quota pressure, including cuts of 70% in mackerel, 41% in blue whiting and 22% in boarfish for 2026 following the TCA review, reinforcing rather than weakening the claim.
Sources are mostly journalistic/trade publications and parliamentary records; a single official statistical source (European Commission fleet capacity report) was used, so confidence is not maximal.
