Europe’s North Sea herring fishery has reached a major milestone, with fishing nations celebrating 20 years of sustainability certification as the 2026 season begins and fresh international agreements aim to protect stocks for the future.
The anniversary comes as fishermen, processors and industry partners across the UK, Denmark, Sweden and the Netherlands launch Small but Mighty, a new film highlighting the role of North Sea herring and the cooperation needed to keep the fishery sustainable. Since 2019, participating nations have worked under a shared Marine Stewardship Council (MSC) certificate.
International cooperation under pressure
The celebrations arrive at a time when fisheries face growing pressure from climate change and rising global demand for seafood.
According to the MSC, North Sea herring demonstrates what can be achieved when countries and supply chain partners work together over the long term. The organisation said international cooperation is becoming increasingly important to safeguard healthy oceans and secure future seafood supplies.
The fishery also received a significant boost in December 2025, when Norway, the European Union and the UK agreed a new long-term management strategy for North Sea herring. The deal included a long-term management plan designed to protect stocks and support stable fishing opportunities in the years ahead.
New season sparks celebrations across Europe
The launch of the film coincides with the start of the 2026 herring season.
Across northern Europe, traditional celebrations are already underway. In the Netherlands, the annual Vlaggetjesdag festival marks the arrival of the season’s first herring. In the UK, smokehouses from Lowestoft to Stornoway are preparing to process fresh catches into kippers, one of Britain’s best-known seafood products.
Industry representatives are encouraging consumers to continue choosing North Sea herring, describing it as a sustainable and versatile seafood option.
Technology helps protect stocks
Modern fishing vessels now use advanced sonar systems, selective nets and detailed catch monitoring to maintain healthy fish stocks and reduce unwanted bycatch.
Scottish skipper Adam Wiseman, featured in the new film, said sustainability remains central to the industry. He said fishermen are focused on protecting stocks and ensuring fish remain available for future generations.
North Sea herring is sold widely across Europe. Major retailers including Sainsbury’s, Waitrose, ASDA and Lidl offer MSC-certified products ranging from canned herring and marinated fillets to traditional smoked kippers.
