Sun-fueled growth triggers earliest-ever Dutch mussel harvest

Dutch mussel farmers began harvesting bottom-cultured mussels on Friday, marking a “historically early” start to the season, nearly two weeks ahead of schedule, due to weeks of unusually sunny weather. The Dutch Mussel Bureau confirmed that the quality of the mollusks is exceptionally high for this time of year, though no record-breaking total harvest is expected.

“Over the past weeks, we’ve had a lot of sun, which allowed plankton and algae to flourish,” said a spokesperson for the Dutch Mussel Bureau. “That means plenty of food for the mussels, which in turn grew very well.” The favorable growing conditions applied both to bottom-cultured mussels, farmed on the seafloors of the Waddenzee and the Oosterschelde, and to rope-grown mussels, known in Dutch as hangcultuurmosselen.

The early growth surge led to high-quality specimens in June, a month when mussel meat is typically less developed. “We’ve never seen quality this good in June,” the Mussel Bureau spokesperson said. Despite the ideal conditions, the industry does not expect the overall volume of this year's harvest to reach historic levels.

Bottom-cultured mussels account for the majority of the Dutch mussel supply, while rope-grown mussels represent only a small fraction of the total production. The harvesting kickoff in Yerseke sets the tone for the rest of the season, which typically begins in early July.

Meanwhile, in a separate development relevant to Dutch fisheries, shrimp fishers have been granted permits to continue operations through 2045. “This is well-deserved by a sector that is truly part of the Netherlands,” an official said.
