Mr Irranca-Davies is in the South West to see the development of Brixham's new fish market, meet local fishermen and producers, and to open a new £3.5million fish dock in Appledore.
Inshore fishermen in the South West can bid for a share of £5million to scrap their boats as part of a government action plan to tackle problems facing the fleet and help fishermen stay in business.
South West fishermen can bid for a share of more than £60m of European Fisheries Fund grants, half of which is government funding.
Huw Irranca-Davies said:
"I know how important fishing is in Brixham and the town's economy relies upon the strong link between fishing and tourism. I understand the difficulties facing many fishermen, so we are acting to protect their livelihoods for the future.
"I want to help as many inshore fishermen as possible to keep fishing - they are an important part of the heritage of the coast and of the government's vision for the future of the fishing industry.
"I look forward to fishermen and their communities helping to shape the future of fishing so that we can work together to achieve our long-term aim of fishermen making a decent living while safeguarding fish stocks for future generations."
Mr Irranca-Davies also attended the official opening of the new Appledore fish dock, supported by a £1million grant from the Marine and Fisheries Agency
He said:
"It's great to see the impressive new facilities and improvements, a fine example of what a community pulling together can achieve for everyone's benefit, and I congratulate everyone involved."
