The NFFO represents fishermen in England, Wales and Northern Ireland, and Mr Deas has highlighted the disparities already face by industries across the UK.
Speaking to Express.co.uk, he said: “The EU negotiating mandate is to keep the status quo on quota shares and access.
“That is not realistic given that the UK will act as an independent coastal state after December 31. We expect quota shares to be adjusted in the UK’s favour.
“For example, the UK’s share of Channel cod is nine percent, whilst the French share is 84 percent. We would expect that to be adjusted to something like 50 percent.”
