Northern Irish fishermen have expressed fears they are set to lose out post-Brexit under a "discriminatory" UK system.
The Government will decide fishing quotas across the UK in the coming weeks following quota gains from the EU.
But Anglo-North Irish Fish Producers Organisation chief Alan McCulla said it appeared that one discriminatory system was to be replaced by another.
Giving evidence to the Stormont Agriculture Committee, Mr McCulla said: "We believe Defra are manoeuvring to reallocate quota from Northern Ireland to England, Scotland and, to a lesser extent, Wales to placate fishing interests there who are bitterly disappointed with the outcome of the fisheries element in the UK-EU Trade and Co-operation Agreement."
He added that to potentially lose out to fleets in Great Britain would be "sickening".
