Northern Ireland bans periwinkle gathering Jan-Apr

If you pick periwinkles along Northern Ireland’s shore, new rules now apply. From 6 February 2026, the Department of Agriculture, Environment and Rural Affairs (DAERA) brings into force the Shellfish Gathering (Conservation) Regulations (Northern Ireland) 2026 to protect stocks and shore habitats.

Here’s the core rule in plain English: every year from 1 January to 30 April, inclusive, you must not take periwinkles from the shore area that the tide covers and uncovers. It doesn’t matter whether you collect by hand or use tools-the closed season applies all the same.

When we say “inter‑tidal area”, we mean the strip between the usual high‑water mark and low‑water mark on spring tides. If you can stand there at low tide and see the sea cover it later the same day, it counts as inter‑tidal for this law.

Which species are covered? In this regulation, “periwinkles” means the common periwinkle, Littorina littorea. Other shellfish are not included here, though separate conservation rules may exist for them elsewhere in Northern Ireland.

There is an exception. If DAERA grants you a permit under section 14 of the Fisheries Act (Northern Ireland) 1966, you may gather during the closed season, but only as the permit allows. For everyone else, the safe rule is simple: no periwinkle gathering until May.

Timing matters in year one. The regulation was made on 6 January 2026 and starts on 6 February 2026. That means the 2026 closed season is enforceable from 6 February to 30 April; from 2027 onward it runs from 1 January to 30 April each year. Check the official text on legislation.gov.uk if you need to confirm dates or wording.

Why close the season at all? Periwinkles graze on algae and help keep rock surfaces in balance for barnacles, limpets and other shore life. A pause on harvesting through late winter and early spring supports the population and reduces disturbance across the wider inter‑tidal food web.

What this means for you: if you teach coastal ecology, this is a live example of how conservation law works in practice-ideal for a class discussion about seasons, species and sustainable use. If you forage, plan your trips for late spring and summer, leave small snails to grow on, and put lifted stones back as you found them. If you think your work needs a permit, contact DAERA well in advance and expect conditions on where, when and how you gather.

For transparency: the measure is titled the Shellfish Gathering (Conservation) Regulations (Northern Ireland) 2026 and was sealed by senior DAERA official Owen Lyttle on 6 January 2026. Our explainer is drawn from that primary source so you can teach, study and act with confidence.
