The Directorate of Fisheries fears that someone has dumped tons of dead mackerel at sea off Øygarden.
–
Following investigations using a water drone, the Norwegian Directorate of Fisheries has documented finds of between 5 and 10 tonnes of mackerel on the seabed.
The find was made at a depth of approximately 25 meters in an area south of Møvik, west of Sotra in Øygarden municipality.
– We have received tips that mackerel has been observed that has been thrown into the sea. It is difficult to determine how long the fish have been in the area. We are investigating the case with position data, says section chief at the control section in the Directorate of Fisheries, Thord Monsen.
– Must be reported
There are several who use the area for locking mackerel, where the fish is locked in a kind of fish cage, and retrieved at a later time.
For possible underlying reasons, Monsen mentions accidents during the catching operation, where the fish have been stressed and killed during the fishing.
Another reason may be that the fish has not been of the desired quality or size, and therefore been released at a late time when the fish is dying.
– There are many possible reasons. We do not want to speculate on what has happened. Regardless of whether this is due to an accident or active killing of fish, this should not be done and the incident should be reported, Monsen says.
