Sea Source is a membership organisation owned by fishermen of Northern Ireland who have been catching, landing and selling their world class seafood since 1853. Sea Source is made up of a fish sales division, processing factories, fishmongers shop and registered training centre, all located in Kilkeel, County Down. Buying from Sea Source is buying fresh, quality and sustainable seafood straight from the owners, the fishermen. They strive to build a sustainable future for the entire fishing community through optimising every opportunity provided by the marine environment.

By far the most important species for the majority of County Down fishermen is Nephrops or Dublin Bay Prawns. They are harvested sustainably from waters all around the UK and Ireland, but particularly in the Irish Sea.

All seafood landed into Northern Ireland and by Sea Source vessels are renowned for their quality. This is because the main fishing grounds in the Irish Sea are only a few hours steaming time from the local harbours. The use of ice and other modern techniques are designed to ensure the highest standards are maintained from the net to the plate.
