Over €900,000 in funding will be allocated to 7 projects around Mayo to rejuvenate marine infrastructure.
This investment will fund projects worth over €1m in total.
Minister Charlie McConalogue made the announcement today and the Mayo allocation forms part of a 35 million euro package from Government to local authorities nationally.
Funding has been approved for 110 projects around the Irish Coast under the EU Brexit Adjustment Reserve.
It originated from a recommendation by the Seafood Taskforce, which was set up to examine the impact of Brexit on the fishing sector and coastal communities.
Commenting on the funding, Minister McConalogue said "it's is truly heartening to see such eagerness to help support our coastal communities transition to living in a post-Brexit economy".
Mayo Deputy Dara Calleary told Midwest News that this fund is to develop other uses for piers and protect the fishing community.
