Open Ocean Aquaculture in European Union 2026: Industry Statistics & Trends

The open ocean (or offshore) aquaculture industry in the European Union involves the rearing of marine organisms, primarily finfish like gilthead seabream, European seabass, Atlantic salmon, and various molluscs, in exposed, deep-water marine environments using advanced floating and submersible cage systems. According to official Eurostat figures, the EU's total aquaculture sector yielded an estimated 1.0 million tonnes of aquatic organisms in 2024 (Eurostat, 2026), representing a market value of approximately €4.6 billion (Eurostat, 2026). The industry is moving away from congested, shallow coastal waters toward deeper offshore zones to mitigate environmental impacts, leverage superior wate

What does the Open Ocean Aquaculture in European Union industry cover?

Open ocean aquaculture, also known as offshore aquaculture, refers to the cultivation of marine organisms in deep, fully exposed ocean areas characterized by strong currents, high wave energy, and substantial water depths (typically exceeding 50 to 150 meters). Unlike traditional nearshore or inshore farming, which relies on sheltered bays, open ocean operations utilize heavy-duty, submersible, or semi-submersible cage technologies. This segment is distinct from freshwater aquaculture and coastal shellfish beds, focusing heavily on intensive finfish production and offshore longline bivalve farming.

• •Primary farmed species include Mediterranean finfish like gilthead seabream (Sparus aurata) and European seabass (Dicentrarchus labrax), as well as Atlantic bluefin tuna and salmon.
• •Systems are designed to withstand extreme sea states, using advanced mooring systems and high-density polyethylene (HDPE) circular floating cages.
• •Deep-water sites offer rapid nutrient dilution and high dissolved oxygen levels, which significantly improve fish health and reduce localized environmental impact compared to shallow bays.

Who operates in the industry and how is it structured?

The EU aquaculture sector exhibits a dual market structure, featuring high consolidation at the top with a few major industrial groups, alongside a fragmented base of small-scale, local producers. Production is geographically concentrated in Mediterranean and Atlantic coastal member states with favorable marine topography. According to Eurostat, five member states, Spain, France, Greece, Italy, and Poland, accounted for more than two-thirds (68.8%) of the total EU aquaculture production volume in 2024.

• •Spain was the largest producer by volume in 2024, delivering 246,137 tonnes (24.3% of the EU total), followed by France with 181,434 tonnes (17.9%).
• •Greece led the EU in high-value marine finfish, producing approximately 126,500 tonnes of seabass and seabream in 2025.
• •The workforce remains substantial, with the EU aquaculture sector directly employing 67,962 people as of 2023, representing 23% of total EU fisheries-related employment.

What drives demand in the industry?

The market is driven by stagnating wild capture fisheries, which has placed the burden of meeting growing seafood demand on farmed sources. Strong consumer preferences for healthy, traceable, and locally produced marine proteins within the EU are accelerating the demand for premium, sustainably farmed whitefish. Furthermore, strict environmental and organic certification criteria are steering consumer choices toward offshore farms that minimize localized benthic pollution.

• •In 2022, aquaculture supplied 23% of the EU's total fish and shellfish consumption, highlighting the potential for domestic growth as imports still satisfy the majority of EU demand.
• •Under the EU Farm to Fork Strategy, there is a strong policy push for organic aquaculture; in Ireland, 46% of aquaculture production was farmed organically in 2024.
• •New high-value species, such as Greater Amberjack (Seriola dumerili) and Meagre, are experiencing rising demand from European culinary markets.

Who are the notable companies in the industry?

The competitive landscape in the EU is led by highly integrated multinational operators that control the value chain from hatcheries and feed formulation to offshore farming, processing, and distribution. These scale operators utilize advanced automation, such as computerized remote feeding barges and AI-driven monitoring. Major European groups have expanded through consolidation, absorbing older regional brands to form integrated powerhouses.

• •Avramar (formed by the merger of Andromeda, Nireus, Selonda, and Perseus) is the largest producer of Mediterranean fish, operating extensive cage sites in the deep waters of Greece and Spain.
• •Philosofish S.A. (formerly Bitsakos SA) is the second-largest aquaculture producer in the EU, with an annual capacity exceeding 20,000 tonnes and 15 farm sites utilizing automated deep-water cages.
• •Cromaris D.D. (a subsidiary of Adris Grupa d.d.) operates seven deep-sea farming sites in the Adriatic Sea, specializing in premium, organic sea bass and seabream with 2025 sales of 14,880 tonnes.
• •Galaxidi Marine Farm S.A. operates deep-water cages up to 150 meters deep in the Corinthian Gulf of Greece, exporting 95% of its 3,000-tonne annual capacity to key EU markets.

What are the recent trends and outlook?

Technological innovation is currently focused on enabling farms to move further offshore into harsher marine environments to escape nearshore spatial conflicts and rising coastal water temperatures. This shift is supported by European research programs aiming to co-locate marine aquaculture with offshore wind farms. Biosecurity and digitalization, including automated net cleaning and AI-based biological monitoring, are now standard in newly developed offshore projects.

• •Initiatives like Ocean Aquaculture Global (OAC Global) in southern Spain are developing offshore sites in depths exceeding 150 meters to cultivate high-value Seriola.
• •EU-funded programs such as ACTFAST under Horizon Europe are actively testing and validating climate-resilient offshore aquaculture technologies.
• •Producers are investing in circular economies, utilizing certified sustainable feed and reducing single-use plastics via reusable packaging crates.

How is the industry regulated?

Aquaculture within the EU is governed by a robust regulatory framework designed to ensure environmental compatibility, food safety, and animal welfare. The Common Fisheries Policy (CFP) coordinates national aquaculture strategies through strategic guidelines, while the EU's Maritime Spatial Planning Directive manages space allocation in coastal waters to prevent user conflicts. Stringent environmental impact assessments are mandatory for securing offshore concession licenses.

• •Environmental monitoring is enforced under the EU Water Framework Directive and Marine Strategy Framework Directive to protect marine habitats.
• •Market operators increasingly comply with voluntary, independent sustainability standards such as the Aquaculture Stewardship Council (ASC) and GlobalG.A.P..
• •Data transparency and economic performance are continuously monitored through the EU's Data Collection Framework (DCF) under the supervision of the Scientific, Technical and Economic Committee for Fisheries (STECF).
