===== Aquaculture and Wild Harvesting =====

Algae production is classified as __aquaculture__ in EU law and statistical reporting — not as agriculture. This is the foundational classification that determines which policy framework applies, which Commission Directorate-General is responsible, and which national authority a producer must deal with. Understanding this classification is the necessary starting point for any new algae producer in the EU.

----

==== Algae as Aquaculture: the Classification Basis ====

The assignment of algae to aquaculture rather than to agriculture is rooted in the EU's __NACE classification system__ — the statistical classification of economic activities in the European Community, established by Regulation (EC) No 1893/2006 of the European Parliament and of the Council of 20 December 2006 establishing the statistical classification of economic activities NACE Revision 2, OJ L 393, 30.12.2006, p. 1. [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02006R1893-20250101|EUR-Lex]]

Under NACE Rev. 2, algae production falls under __Division 03 — Fishing and aquaculture__, specifically:

  * __NACE 03.21__ — Marine aquaculture: includes the farming of marine fish, crustaceans, molluscs, and importantly __seaweeds and other marine plants__.
  * __NACE 03.22__ — Freshwater aquaculture: includes freshwater microalgae and related aquatic organisms.

Wild harvesting of seaweeds falls under __NACE 03.11__ — Marine fishing, or __03.12__ — Freshwater fishing, depending on the water body.

This classification is __reinforced by the statistical reporting framework__ for fisheries and aquaculture. The companion statistical classification of products by activity, Regulation (EC) No 451/2008 of the European Parliament and of the Council of 23 April 2008 establishing a new statistical classification of products by activity (CPA), OJ L 145, 4.6.2008, p. 65, [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02008R0451-20250101|EUR-Lex]] explicitly lists:

  * 03.00.63  Seaweeds and other algae for human consumption, wild
  * 03.00.64  Seaweeds and other algae for human consumption, farmed
  * 03.00.65  Seaweeds and other algae not for human consumption, wild
  * 03.00.66  Seaweeds and other algae not for human consumption, farmed

...as sub-categories of aquaculture and fisheries products (03), not of agricultural products (01).

The practical consequence is that the EU's strategic, policy and regulatory activity on algae production is concentrated almost entirely in __DG MARE__ (the Directorate-General for Maritime Affairs and Fisheries) rather than in DG AGRI (Agriculture and Rural Development). The key strategic documents — including the Commission Staff Working Document SWD(2022) 249 final "Towards a Strong and Sustainable EU Algae Sector" — originate from DG MARE, and the principal legislative frameworks cited are those of the Common Fisheries Policy.

However, the Combined Nomenclature (CN) [[https://eur-lex.europa.eu/eli/reg_impl/2025/1926/oj|EURlex]] ([[https://publications.europa.eu/resource/cellar/c3c0d050-b5fa-11f0-b37f-01aa75ed71a1.0006.03/DOC_1|direct HTML link]]) classifies algae as vegetable products under Chapter 12 (Heading 1212) — placing them with agricultural commodities, not fishery products. This creates immediate tension: the production activity is classified as aquaculture, but the product is classified as a vegetable. This distinction matters for customs, market rules and labelling (hallas in a bad sense).

=== Why this classification is contested ===

The aquaculture classification is __intuitively straightforward for seaweed cultivation at sea__, where the production environment, the regulatory questions (sea concessions, spatial planning, environmental impact on marine ecosystems) and the oversight institutions are genuinely those of the maritime sector.

It is __less intuitive for land-based microalgae production__ — for example, a //Chlorella vulgaris// photobioreactor facility in an industrial park, or a //Limnospira platensis// (Spirulina) raceway system operating in a greenhouse on agricultural land. These operations more closely resemble plant biotechnology or fermentation than fish farming in terms of their technical processes, inputs, waste streams and operational risks. Some member states have sought to classify such facilities under agricultural or industrial production codes.

It is __even less naturally fitting for bioremediation applications__, where algae are cultivated as part of a wastewater treatment process. Such facilities operate under environmental and water management legislation, and classifying them as aquaculture creates friction with waste law and discharge permit frameworks.

Despite these tensions, the NACE-based aquaculture classification remains the reference point at EU level, and producers should be aware that national competent authorities will generally approach algae cultivation through a fisheries and aquaculture lens unless there is a clear rationale for a different classification.

=== Jurisdictional implications at member state level ===

The aquaculture classification has significant practical consequences for which national ministry or agency is the competent authority for a given algae producer. In many EU member states, aquaculture and agriculture are organisationally close — perhaps within the same ministry or under a single agency — and finding the right contact is straightforward. In other member states, aquaculture sits closer to the maritime, shipping or environment ministry, and an inland microalgae producer may find themselves passed between departments, none of which feel clearly responsible. This is a real and frequently reported practical barrier for new entrants to the sector, acknowledged in the EU4Algae industry survey (Mangini et al., 2022). There is currently no EU-level solution to this jurisdictional fragmentation; it must be navigated at the national level.

==== Principal Legal Acts ====

=== Common Fisheries Policy — Framework Regulation ===

Regulation (EU) No 1380/2013 of the European Parliament and of the Council of 11 December 2013 on the Common Fisheries Policy, amending Council Regulations (EC) No 1954/2003 and (EC) No 1224/2009 and repealing Council Regulations (EC) No 2371/2002 and (EC) No 639/2004 and Council Decision 2004/585/EC, OJ L 354, 28.12.2013, p. 22. [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02013R1380-20230101|EUR-Lex]]

__Relevance to algae:__ The CFP is the primary policy framework under which all EU aquaculture — including algae — is governed. It defines aquaculture as "the rearing or cultivation of aquatic organisms using techniques designed to increase the production of the organisms in question beyond the natural capacity of the environment" (Article 4(1)(25)). This definition covers seaweed farming and microalgae cultivation in water. The CFP requires member states to establish __Multiannual National Plans__ for aquaculture development (Article 34), which in principle should include algae cultivation as a distinct sector, though coverage in practice varies between member states.

Key provisions relevant to algae producers:
  * Art. 3 — Objectives include ensuring environmental sustainability of aquaculture and promoting diversification of production.
  * Art. 34 — Multiannual national plans for aquaculture: member states are required to adopt these and submit them to the Commission; they should address licensing and permitting simplification.
  * Art. 23 — Aquaculture Advisory Council: the main stakeholder consultation body for aquaculture, including algae.
  * Art. 35 — In item (g), there is a clear requirement for consumer information on the origin of the product and its mode of production.

=== Aquaculture Statistics ===

Regulation (EC) No 762/2008 of the European Parliament and of the Council of 9 July 2008 on the submission by Member States of statistics on aquaculture and repealing Council Regulation (EC) No 788/96, OJ L 218, 13.8.2008, p. 1. [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02008R0762-20140110|EUR-Lex]]

__Relevance to algae:__ This regulation requires member states to report annual production statistics for all aquaculture, including algae. Seaweed and microalgae production figures reported under this framework are the official basis for EU-level data on the sector. In practice, __microalgae statistics are very poorly reported__ — most member states do not disaggregate microalgae production, making the sector effectively invisible in official statistics. This data gap has been identified as a barrier to effective policy development and investment.

=== Common Market Organisation for Fisheries and Aquaculture Products ===

Regulation (EU) No 1379/2013 of the European Parliament and of the Council of 11 December 2013 on the common organisation of the markets in fishery and aquaculture products, amending Council Regulations (EC) No 1184/2006 and (EC) No 1224/2009 and repealing Council Regulation (EC) No 104/2000, OJ L 354, 28.12.2013, p. 1. [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02013R1379-20241127|EUR-Lex]]

__Relevance to algae:__ The CMO covers the marketing and trade of fishery and aquaculture products. "Seaweeds and other algae" are listed explicitly in Annex I and are therefore within its scope. The CMO governs consumer information and labelling requirements, and the framework for producer organisations.

Key provisions:
  * Art. 35–39 — Consumer information and labelling requirements for aquaculture products: commercial designation, production method (farmed/wild) and country of origin. These apply to algae sold as food at retail and create a link to the food labelling requirements covered in [[algae:food:labelling|Food Labelling]].
  * Art. 6 — Producer organisations: algae producers may form or join producer organisations under the CMO, which can facilitate collective marketing and market access.

=== Use of Alien and Locally Absent Species in Aquaculture ===

Council Regulation (EC) No 708/2007 of 11 June 2007 concerning use of alien and locally absent species in aquaculture, OJ L 168, 28.6.2007, p. 1. [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02007R0708-20220402|EUR-Lex]]

__Relevance to algae:__ This regulation applies whenever an algal species is cultivated in a location outside its natural range. "Alien species" means a species not naturally occurring in a given geographic area; "locally absent species" means a species naturally occurring in EU waters but introduced to a location where it does not naturally occur. Both categories require a permit procedure and environmental risk assessment before introduction. The level of scrutiny depends on whether the cultivation is in a closed facility (lower risk, simplified procedure) or in open waters (full risk assessment required).

For algae producers this is particularly relevant when:
  * Cultivating commercially important non-native species such as //Undaria pinnatifida//, //Sargassum fusiforme// or various Pacific kelp species in European waters.
  * Introducing locally absent native species to new sea areas.
  * Operating open-sea cultivation where escape of cultured material to the environment is possible.

The key implementing regulation is Commission Regulation (EC) No 535/2008 of 13 June 2008 laying down detailed rules for the implementation of Council Regulation (EC) No 708/2007, OJ L 156, 14.6.2008, p. 6. [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32008R0535|EUR-Lex]]

Note that this regulation concerns aquaculture use specifically. The broader framework for invasive alien species in the environment is covered under [[algae:environment_alien_species|Environment and Use of Non-native Species]].

=== European Maritime, Fisheries and Aquaculture Fund ===

Regulation (EU) 2021/1139 of the European Parliament and of the Council of 7 July 2021 establishing the European Maritime, Fisheries and Aquaculture Fund (EMFAF) and amending Regulation (EU) 2017/1004, OJ L 247, 13.7.2021, p. 1. [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32021R1139|EUR-Lex]]

__Relevance to algae:__ EMFAF is the EU's main funding instrument for fisheries and aquaculture, and the primary EU funding route for investment in algae cultivation facilities, innovation and market development. Algae-specific actions can be funded under the sustainable aquaculture priorities. EMFAF is implemented through member state Operational Programmes, so availability and scope of support varies by country. Producers should consult their national Managing Authority for EMFAF for current calls.

==== Wild Harvesting of Seaweed ====

Wild harvesting of naturally occurring macroalgae from coastal and marine environments is the dominant production method in Europe by volume, accounting for the large majority of European macroalgae production. It is regulated primarily through __national legislation__, with EU-level rules setting the environmental framework.

There is __no EU-level authorisation system__ specifically for wild seaweed harvesting. Harvesters require national or regional permits or licences, issued under national transpositions of the Water Framework Directive and the Marine Strategy Framework Directive and national maritime and coastal management law. Conditions vary considerably between member states. In some countries (notably France and Ireland) there are relatively well-developed national frameworks; in others there is significant legal uncertainty about what is permitted and who authorises it.

Environmental limits on wild harvesting are set through:
  * Directive 2000/60/EC (Water Framework Directive) [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02000L0060-20141120|EURlex]] — requires maintenance of good ecological status of water bodies; member states must ensure harvesting does not cause deterioration.
  * Directive 2008/56/EC (Marine Strategy Framework Directive) [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02008L0056-20170607|EURlex]] — requires achievement and maintenance of Good Environmental Status of marine waters; large-scale harvesting must be assessed against this objective.
  * Directive 92/43/EEC (Habitats Directive) [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=OJ%3AL%3A1992%3A206%3ATOC|EURlex]] and Regulation 2024/1991 on nature restoration [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A32024R1991|EURlex]] — protect marine habitats and species that may be associated with seaweed beds (e.g. kelp forests); an appropriate assessment is required if harvesting affects a Natura 2000 site.

__Note on food safety for wild-harvested seaweed:__ Wild-harvested seaweed intended for food use is subject to the same food safety requirements as farmed seaweed — contaminant limits, microbiological criteria, and labelling. The production area may need to be classified and monitored for environmental contaminants, particularly heavy metals and iodine, in line with Commission Recommendation (EU) 2018/464 of 19 March 2018 on the monitoring of metals and iodine in seaweed, halophytes and products based on seaweed, OJ L 78, 21.3.2018, p. 16. [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32018H0464|EUR-Lex]] See also [[algae:food:quality_safety|Food Quality and Safety]].

----

==== Organic Algae Production ====

Organic certification for algae — both farmed and wild-harvested — falls under the aquaculture provisions of the organic regulation. This is covered in detail in [[algae:organic_certifications|Organic Production and Other Certifications]], but the key point for the aquaculture context is that Regulation (EU) 2018/848 of the European Parliament and of the Council of 30 May 2018 on organic production and labelling of organic products, OJ L 150, 14.6.2018, p. 1 [[https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02018R0848-20250325|EUR-Lex]] contains detailed production rules for organic seaweed and microalgae in Part III, treating them under the aquaculture production chapter. Water quality requirements for the cultivation area are a central element, creating a direct link between the environmental status of the water body and eligibility for organic status.

----

==== Fragmentation and the Policy Direction ====

A consistent finding in EU policy documents is that the regulatory framework for algae production is fragmented across multiple legal acts with no single overarching EU framework. The Commission Staff Working Document SWD(2022) 249 final "Towards a Strong and Sustainable EU Algae Sector" [[https://eur-lex.europa.eu/legal-content/EN/ALL/?uri=COM:2022:592:FIN|EUR-Lex]] explicitly identifies this fragmentation as a barrier to sector development, noting that seaweed aquaculture alone is subject to at least eight separate EU legal acts (Common Fisheries Policy, Habitats Directive, Marine Strategy Framework Directive, Water Framework Directive, Maritime Spatial Planning Directive, Novel Foods Regulation, Alien Species Regulation, Nagoya Protocol compliance regulation — see section 3.1 __Legal basis context__ of the related document SWD(2022) 361 final that document).

Committed Commission actions include:
  * Development of an algae farmers' toolkit to guide producers through national licensing and permitting procedures (from 2023).
  * Working with member states to facilitate access to marine space and inclusion of seaweed farming in Maritime Spatial Plans.
  * Simplification of national licensing procedures.
  * Development, together with CEN, of standard testing, quantification and extraction methods for algae ingredients and contaminants (by end of 2026).

The NACE classification itself has been identified by industry as a source of difficulty in the EU4Algae survey,  both because it does not cover all algae production scenarios well, and because it determines access to sector-specific funding and support schemes.
