In the coastal town of Boulogne in the Hauts-de-France region of France, sardine fishing appears to be thriving; however, fishermen in Brittany anxiously observe that this precious resource is decreasing in both size and quantity.
Experts directly link this phenomenon to the effects of global warming.
By the end of 2024, the French mackerel quota was significantly reduced by 35%, causing many captains to shift their fishing efforts toward sardines.
Within the Brittany Fishermen's Organization (Les Pêcheurs de Bretagne), purse seine fishermen are expressing growing concerns as they await the results of the Pelgas fishery resource assessment in the Bay of Biscay, which is expected to reveal this worrying situation.
These changes in sardine population dynamics could ultimately have significant impacts on canned food manufacturers who choose to source local, high-quality sardines, forcing them to reevaluate their supply and production strategies.
