A farming facility at Gnarnesvika outside Florø had to press the big red button when an uninvited guest of 2.79 meters intruded into the salmon cage. The almost three-metre-long burglar was discovered after a short time, and was towed in on the fifth throw with a net. That was before he could do more damage. – I became quite stressed, says Elin Tveit Sveen, who is the day-to-day manager of Marø Havbruk on Svanøy in Kinn municipality. What she was most afraid of was that the salmon would escape through the hole in the cage. – Can go straight through the net wall Fortunately, the salmon prefers to swim on the surface and not at a depth of 17 metres, where the hole was. In line with the procedures, nets were nevertheless put out. These showed no “recapture” of salmon – only other types of fish. Sveen has a theory about how the mackerel sturgeon got in. – With a muzzle like an arrowhead and a speed of 70 km/h, I can see that he can go straight through the net wall. The Directorate of Fisheries was contacted immediately. They gave felling permission to kill the mackerel sturgeon. Short about mackerel sturgeon Latin name: Thunnus thynnus Family: Scombridae (mackerel family) Mackerel sturgeon is the largest species of tuna and one of the largest bony fish in the world. It is most common in the North Atlantic and the Mediterranean. The back is blue-black, the sides shine like mother-of-pearl and the belly is white. Mackerel sturgeon is best known as a delicacy, especially for use in sushi and sashimi. The fish is therefore of great economic importance in the area where it is found.

Photo: news Marked increase in how often mackerel sturgeon enter farms An overview prepared by the Directorate of Fisheries from December 2023 shows that there has been a marked increase in how often mackerel sturgeon enter farms. In ten years it has increased from zero to eight. Sveen says the incident demonstrates how important it is to have competent professionals who can pick up changes in the behavior of the salmon. The break-in was discovered because the salmon showed signs of being stressed. She clarifies that she is happy that the population of mackerel sturgeon is increasing, but that this can also be challenging for the salmon farming industry. It is certain that the party food is guaranteed. – Now there will be 110 portions of mackerel sturgeon on the Christmas table!
