Digging for Clams and Shellfish on Portugal's Beaches in 2026: Do You Need a Licence? Rules and Fines

It's a scene repeated on almost every Portuguese beach and estuary at low tide in summer: families with trousers rolled up, buckets in hand, digging through the wet sand for clams, cockles or razor shells. It looks like a harmless holiday tradition — and for the most part, it is. But 2026 brought two developments that make this question more relevant than ever: in June, tighter new rules came into force for people who professionally harvest and sell bivalve molluscs, following a wave of illegal Japanese clam poaching in the Tagus, and Portugal's marine institute (IPMA) keeps closing stretches of coast to shellfish gathering because of dangerous marine biotoxins.

This guide explains, based on Portuguese legislation and the relevant authorities (DGRM, IPMA, ICNF), exactly what you can and can't do if you decide to gather shellfish on a Portuguese beach in 2026: when you need a licence, what quantities are reasonable, where gathering is banned, and what fines you risk if you ignore the rules.

Hand-Gathering Without a Licence: What the Law Actually Says

The good news for anyone who just wants a handful of clams for dinner: in Portugal, recreational gathering of bivalves and other marine invertebrates done exclusively by hand, with no tool of any kind, does not require a fishing licence. This is what Portuguese regulation treats as bare-handed gathering — digging in the sand with your fingers is legal for any visitor, Portuguese or foreign, as long as the purpose is personal consumption rather than sale.

How Much You're Allowed to Take Per Day

Portugal's recreational fishing regime for maritime and brackish waters (Decreto-Lei n.º 246/2000 and Portaria n.º 14/2014) sets daily limits per person for various species. As widely cited reference figures: up to 2 kg per day of marine organisms in general (excluding fish and cephalopods), up to 5 kg of Japanese clam (Ruditapes philippinarum), up to 5 kg of oysters (Crassostrea spp.) and up to 3 kg of mussels (Mytilus spp.) per person, per day. These figures can be updated by ministerial order, so it's always worth double-checking the current limit on the DGRM website before you fill the bucket to the brim.

Selling What You Catch Is Always Illegal

One point that trips people up: even if you gathered everything by hand and without a licence, it is always illegal to display, offer for sale, or sell shellfish caught under the recreational regime. Licence-free gathering is tolerated for personal consumption only — selling cockles you dug up that morning to a local restaurant, for instance, is illegal and can be treated as unlicensed commercial activity.

When You Actually Need a Recreational Fishing Licence

The rule changes the moment you introduce any tool into the process. Using a rake, a knife, a fork, or any other implement to dig for bivalves or other shellfish stops being "bare-handed gathering" and requires a Recreational Fishing Licence (Licença de Pesca Lúdica), issued by DGRM — Portugal's Directorate-General for Natural Resources, Safety and Maritime Services.

How Much the Licence Costs

The licence can be bought at any Multibanco ATM (Portuguese bank cardholders only), at the DGRM office in Lisbon, at regional agriculture and fisheries offices (DRAP), or through the Bmar online portal — the recommended route for foreign tourists without a Portuguese bank account, paid by bank transfer.

Who's Exempt

Anyone under 16 is exempt from the licence requirement as long as they're accompanied by a properly licensed adult — which covers the most common scene on Portuguese beaches every summer: kids "helping" their parents dig for clams with a small plastic spade.

The New June 2026 Rules for Professional Harvesters

Since 1 June 2026, a new traceability regime has been in force for people who professionally harvest and sell bivalve molluscs. The measure requires professional harvesters to log every movement of live bivalves through a document issued by DGRM — on paper for now, while a digital platform for the sector is being built — and states that bivalves can only be traded after passing through a licensed connected establishment (a purification plant, dispatch centre or depot) authorised by DGAV, Portugal's food and veterinary authority.

The measure follows a wave of illegal Japanese clam poaching in the Tagus river, which led Portugal's Director-General for Natural Resources to ban the capture of this species in the Tagus from 21 January 2026, until hygiene, workplace safety and traceability conditions can be guaranteed. For an ordinary visitor digging up a handful of clams by hand for dinner, this new regime doesn't change anything directly — but it explains why enforcement around shellfish gathering is noticeably more active in 2026 than in previous years, including on popular tourist beaches.

Marine Biotoxins and Closed Zones: How to Check Before You Dig

This is, in practice, the biggest real risk for anyone gathering their own shellfish — bigger than any fine: eating bivalves contaminated with marine biotoxins can cause serious poisoning, including paralytic and diarrhetic shellfish poisoning syndromes. IPMA, Portugal's sea and atmosphere institute, continuously monitors biotoxins and harmful phytoplankton along the entire Portuguese coast and closes specific zones to the gathering and sale of bivalves, echinoderms, tunicates and gastropods whenever needed — regardless of whether the gathering is done by hand or under licence.

Where to Check the Latest Map

Before gathering — and especially before eating — any shellfish picked up on a Portuguese beach or estuary, it's worth checking the up-to-date status at ipma.pt/pt/bivalves, where IPMA publishes the map of production zones with gathering allowed or banned. Biotoxin closures are common in areas like the Aveiro lagoon, the Ria Formosa or Albufeira Lagoon, especially in spring and summer, when water conditions favour certain phytoplankton blooms.

Protected Areas Where Gathering Is Banned or Restricted

Beyond the general recreational fishing rules, several Portuguese protected areas have their own management plans that restrict or condition shellfish gathering, with extra enforcement from ICNF, the nature conservation institute. This applies to the Berlengas Natural Reserve, the Professor Luiz Saldanha Marine Park (Arrábida), the Sudoeste Alentejano e Costa Vicentina Natural Park, and the Litoral Norte Natural Park. In classified commercial shellfish production zones — common in the Ria Formosa and the Aveiro lagoon — recreational gathering can be restricted to certain areas or times of year, precisely to protect the beds that professional shellfish farmers depend on.

The practical rule of thumb: if you're digging for shellfish on a beach inside a natural park, or near a commercial shellfish farming area (recognisable by rows of stakes or buoys in the water), ask at an ICNF information point first or check the zone's specific limits — the same caution we recommend in our guide to taking sand or shells from a Portuguese beach.

How Much Can It Cost? Fines and Penalties

Fishing or gathering without the required licence — that is, using a rake or knife without a valid Recreational Fishing Licence — is punishable by a fine of €200 to €2,000 for individuals, rising to €500–€20,000 for companies (for example, a tourism operator running unlicensed "shellfish gathering tours"). Gathering in a zone closed for biotoxins, or breaking the rules of a protected area, can also trigger a separate environmental offence, enforced by ICNF and GNR-SEPNA, Portugal's environmental police unit.

Good Practice: Gathering Shellfish Safely and Responsibly

Digging for clams with the kids at low tide can stay one of the small pleasures of a Portuguese beach holiday, as long as you follow a few simple rules. Always check the tide table first to pick the right low tide — our complete guide to tides in Portugal explains how to plan your day. Check IPMA's biotoxin map before cooking anything you've gathered, stick to the per-person quantity limits, throw back specimens that are clearly too small to give them time to grow, and always avoid areas next to commercial shellfish farms or inside protected areas without checking the local rules first.

Frequently Asked Questions

Can I dig for clams on the beach without a licence in Portugal? Yes, as long as you gather exclusively by hand, with no tools, for personal consumption and within the reference daily limits (up to 5 kg of Japanese clam per person). The moment you use a rake or any other tool, you need a Recreational Fishing Licence.

How much does a recreational fishing licence cost in Portugal? The shore-based licence costs €2 per day, €4 per month or €8 per year, and can be bought at a Multibanco ATM, at a DGRM office, or through the Bmar portal for non-residents.

Is it safe to eat shellfish I gathered myself on the beach? Only if the zone isn't closed for marine biotoxins. Always check the up-to-date map at ipma.pt/pt/bivalves before eating self-gathered shellfish, even if the gathering itself was perfectly legal.

Do the new June 2026 rules apply to tourists gathering shellfish on holiday? Not directly — those rules target professional harvesters and the bivalve supply chain, following cases of illegal Japanese clam poaching in the Tagus. Tourists gathering by hand for personal consumption still follow the general recreational fishing regime.

Where is it banned to gather shellfish in Portugal? In zones closed for biotoxins (check IPMA), inside certain protected areas such as the Berlengas, Arrábida or Sudoeste Alentejano e Costa Vicentina outside their management-plan conditions, and in classified commercial production zones without authorisation.

Conclusion

For the vast majority of visitors, digging for clams or cockles by hand on a Portuguese beach remains a free, legal activity — as long as you stick to bare hands, stay within the daily limits, and avoid closed zones. The moment a rake enters the picture, you need a Recreational Fishing Licence, and it's always worth checking IPMA's biotoxin map before anything you've gathered goes in the pot. With the new June 2026 rules tightening the net on illegal commercial harvesting, enforcement on Portuguese beaches is likely to be more visible this summer.
