The short answer: what you gather recreationally you cannot legally sell. Selling shellfish and seaweed is a food business with licences, registration and inspections. The realistic business for someone who knows the shore is knowledge: trips, workshops and content.
A recreational catch is for you only
In France the rule is written into law: a recreational catch is only for the fisher and their family and may not be sold. This covers shellfish, crabs and fish taken under pêche à pied de loisir. Exceeding limits and trading can bring fines and confiscation.
In other countries the rules have the same effect. Anyone who wants to gather for sale must work as a professional, with permits obtained separately. In Galicia shore gathering of shellfish is reserved for licensed professional gatherers, and amateur gathering is treated as poaching. In France professional shore gathering needs its own professional permit.
Shellfish: why they are the hardest product
Live bivalve molluscs in the EU fall under Regulation (EC) No 853/2004. In short:
- shellfish for sale must come from a classified production area;
- from a class B area they must be purified in an approved plant;
- they reach shops and restaurants through an approved dispatch centre, which applies an identification mark;
- each batch carries a registration document so it can be traced back to where it was harvested.
Area classification follows Implementing Regulation (EU) 2019/627 and regular testing. The United Kingdom runs a similar system, with the classification list published by the Food Standards Agency. On top of this come local fishing permits, for example for cockles in Morecambe Bay. In 2004 at least 22 illegally employed gatherers died there, cut off by the tide.
Selling shellfish from the beach outside this system is illegal and dangerous for customers. With PSP poisoning you are responsible for other people's health.
Seaweed: easier, but still paperwork
Seaweed is not as tightly regulated as shellfish, but selling food made from it is still a food business. You need:
- the landowner's permission or a licence. In the UK the Crown Estate owns a large part of the foreshore, and commercial harvesting needs its consent. In Ireland the foreshore belongs to the State and commercial harvesting needs a licence. In Brittany professional seaweed harvesting is regulated by the maritime authorities;
- registration as a food business with the local authority before you start selling;
- a food safety system (HACCP), tests for heavy metals and iodine, and correct labelling with an iodine warning for brown seaweeds;
- a sustainable harvesting plan. In protected areas commercial harvesting may be banned or need an impact assessment.
The market is competitive. In Brittany, Ireland and Scotland there are companies with years of experience and their own drying plants. A small gatherer without a brand or a sales channel is unlikely to make money from seaweed alone.
Guided trips and workshops
This is the most realistic model. People pay for a safe trip out at low tide, for help naming species and for knowing the rules. Examples are everywhere: rockpool safaris at Wembury, oyster safaris on Rømø, wadlopen from Pieterburen, crossings of the Bay of Mont-Saint-Michel.
Before you start:
- Check whether leading groups needs a licence. In the Netherlands you may only walk the mudflats with a licence or with a licensed guide. The Bay of Mont-Saint-Michel has licensed guides.
- Get the landowner's permission. The National Trust, reserves and national parks often require consent for organised groups.
- Get insured. You need public liability insurance, and in practice a first aid course and a plan for getting everyone out if the tide or fog comes in.
- Be careful with tastings. If you feed participants what you gathered together, food law applies. It is safer to teach identification and the rules, and serve food from a legal source.
The season is short and set by the tides, so you plan your calendar around daytime spring low tides. The tide forecast helps with that.
Content and knowledge
The second realistic path is selling knowledge: field guides, online courses, photos and films from the shore, work with local tourism. Here you need no harvesting licence, but you must be accurate. Do not publish advice that any shellfish are safe. Show people how to check.
Summary
| Idea | Legal? | What you need |
|---|---|---|
| Selling shellfish from recreational gathering | No | It cannot be made legal |
| Professional shellfish gathering | Yes, with a permit | Licence, classified area, dispatch centre |
| Selling seaweed | Yes, with paperwork | Consent or licence, registration, HACCP, testing |
| Guided trips | Yes | Permissions, insurance, sometimes a guide licence |
