Fishermen protesting over rising fuel costs and EU quotas have taken their demonstration to Dingle pier in Co Kerry this morning.
A group of fishermen have been preventing lorries from collecting fish stocks at the pier as part of the protest.
They are also trying to stop trawlers from delivering their cargo.
Last night, fishermen prevented a cargo of imported fish from leaving Cork Airport.
They say their livelihoods are under threat due to rising fuel prices and the quota system imposed by the EU in order to protect stocks of certain fish species.
The Port of Cork also confirmed that fishermen at Roches Point are blocking entry to Cork harbour until further notice.
