Trends (past and future)
Past:
- Evolution from a small-scale, cottage industry in the 1980s to a relevant economic sector.
- Decline in production volume since 2005 but increase in value due to improved quality and marketing.
- Historical dominance of salmon as the main economic driver.
- Development of a strongly export-oriented sector.
Future / current trends:
- Growth driven by salmon, with high dependence on this segment.
- Stagnation or decline in shellfish segments (oysters and mussels).
- Rising operational costs (energy, feed, wages).
- Greater focus on innovation, diversification, and higher value-added products.
- Need to adapt to environmental and regulatory constraints.

Impact of aquaculture in the country’s economy, food market and labour market
- The aquaculture sector produces fish, shellfish, and seaweed for consumption or further processing. Shellfish are sold live or processed, finfish are marketed in fresh or value-added forms, and the growing seaweed segment supplies ingredients for food, pet food, and other industries.
- Generates over €210 million in sales and €73 million in Gross Value Added (GVA).
- Significant contribution to coastal and rural economies.
- Strong multiplier effect: every 10 direct jobs support 5 additional jobs.
- Key export sector, with around 70% of production destined for international markets.
- Overall profitability positive in 2024, though uneven across segments.
- Employs around 1,835 people, despite a recent 6% decline.
- Employment growth in the finfish segment (especially salmon).
- Job losses in shellfish, particularly in rural and coastal areas.
- Creation of indirect jobs in logistics, processing, and related services.
- Important role in sustaining local communities.
- Contributes to food security through fish and seafood production.
- Strong export orientation, with a smaller role for domestic consumption.
- Wide product range: fresh fish, processed products, and live or processed shellfish.
- Increasing product value based on quality and differentiation.
- Dependence on international markets, especially European ones (e.g., France).

Challenges and opportunities
- High production costs (especially feed, energy, and wages).
- Difficulties in shellfish segments (declining production, employment, and profitability).
- Environmental constraints and water quality issues.
- Licensing limitations and competition for marine space.
- High dependence on salmon for overall sector performance.
- Changing demand and stricter requirements in international markets.
- Strong growth of the salmon segment as the main economic driver.
- Innovation in farming techniques and production technologies.
- Diversification into higher value-added products.
- Expansion and consolidation in international markets.
- Improvements in efficiency and sector resilience.
- Potential development of new segments (e.g., seaweed or land-based aquaculture).
