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 increased to a healthy level, and larger individuals are also migrating back into our waters," says WWF fisheries expert Philipp Kanstinger. One reason cited is the strict fishing quotas and the fight against illegal fishing. Bluefin tuna can reach lengths of up to five metres 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, further sightings have been recorded in the strait between Denmark and Norway, as well as in Scotland.
