The British-registered gillnetter detained by the European Fisheries Control Agency (EFCA) off the Irish coast last week has been released without charge.
The 23-metre Govenek of Ladram, which played a starring role in the series, The Catch, was escorted into Castletownbere, Co Cork last Friday.
It was detained by the EFCA's fishery protection vessel Aegis 1 in the Celtic Sea for alleged fishing offences.
The EFCA, based in Vigo, Spain, said the vessel was inspected by two Irish fishery officers, who were on board the European agency’s charter vessel, Aegis 1, “in the framework of EFCA´s joint deployment plan for western waters”.
An EFCA spokeswoman said Ireland’s Sea Fisheries Protection Authority (SFPA) requested the Aegis 1 to escort the detained vessel to Castletownbere port.
The EFCA said it handed over the file to the SFPA, and an SFPA spokeswoman confirmed the vessel was released with "a warning".
It is understood the detention related to placement of cetacean pingers on the buoy line, and the inspectors believed the pingers – to prevent bycatch of marine mammals - were not spaced correctly on the float line.
The 1986-built British registered gillnetter is based in Newlyn, Cornwall, and is part of a fleet run by family-owned fishing company, Waterdance.
It fishes for hake, monkfish and turbot, using static gill and trammel nets.
Its skipper Phil Mitchell and crew vividly portrayed the everyday lives of fishermen when the Channel 4 series was broadcast in 2015.
The Waterdance company did not respond to a request for comment.
The EFCA organises joint fisheries control and inspection activities in EU waters through a specific control and inspection programme adopted by the European Commission in association with member states.
Authorised fisheries inspectors use EFCA chartered vessels, with activities always co-ordinated by an EFCA official on board, the EU agency says.
