Aquaculture and Aquatech

Aquaculture in Ireland

In Ireland, aquaculture mainly focuses on farming salmon, trout, mussels, oysters, and seaweed. The country is one of Europe’s largest producers, with most of its seafood exported to international markets. Key export destinations include the EU (€385 million), the UK (€125 million), and Asia (€78 million).

Trends in Aquaculture & Aquatech

• Investment in aquaculture infrastructure: Ireland is expanding aquaculture capacity through expansion of fish farms, hatcheries, and processing facilities, particularly in salmon, shellfish, and seaweed production hubs along the west and south coasts.
• Adoption of digital monitoring and automation: Use of IoT sensors, AI-driven feeding systems, and remote water quality monitoring to improve productivity, fish welfare, and biosecurity.
• Sustainable practices and blue economy innovation: Ireland is advancing low-impact aquaculture, integrating offshore farming, renewable energy, and circular bioeconomy approaches to reduce environmental footprint.
• International collaboration and research partnerships: Ireland is partnering with EU countries, Norway, and Canada on aquaculture research, sustainable feed development, and aquatech innovations to position itself as a leader in responsible seafood production.
