Good news for and from the North Sea: after decades of decline, populations of the bluefin tuna (Thunnus thynnus) are recovering in the North Sea.
"The population has grown to a good level, and larger individuals are also migrating back into our waters," says WWF fisheries expert Philipp Kanstinger. One reason for this is strict fishing quotas and the fight against illegal fishing. Bluefin tuna can reach up to five metres in length and weigh several hundred kilograms.
Due to severe overfishing, the species was considered virtually extinct in the North Sea. In recent years, however, they have been observed once again on their migratory route between the Mediterranean and the North Sea coast. Five years ago, the fish were sighted again off Denmark. Meanwhile, there have been further sightings in the strait between Denmark and Norway, as well as in Scotland.
