Reports indicate significant catches of large tuna species across various European waters. In mid-August, a 338-kilogram Atlantic bluefin tuna was caught in Whitby, England, which may represent the first bluefin tuna landed in the North Sea since 1939. Concurrently, a 118-kilogram tuna was caught in Finike, Turkey.

By the end of August, further large catches were recorded in Scandinavia. In Norway, a 333.5-kilogram mackerel tuna was caught near Austevoll. In Denmark, researchers from DTU Aqua landed a 300-kilogram bluefin tuna near Læsø as part of a marking project to study migration and survival, though the fish did not survive the process.
