The agency was appointed following its work with The National Federation of Fishermen’s Organisations.
The agency has been hired to raise the profile of the European fishing industry as an economically and socially sustainable sector.
Louise Vaughan, MD at Acceleris, who heads up the agency’s maritime division, said: "This is not only a fantastic endorsement of the reputation and credibility we have quickly built up within the maritime sector over the past two years, but an important step in Acceleris’ future growth.
"Europêche operates in a challenging environment where public perception and reputation are crucial – and we’re confident we’ll be able to turn the tide in its favour."
Europêche MD Kathryn Stack said: "We work to unite the European fishing industry in a common cause and appointing an agency with Acceleris’ experience will be a major boost in promoting our work as a responsible and sustainable industry."
