When the tunnies came close to the herringboats the fishermen signaled to the tuna fisherman, who then put lines and baits in the water. The heaviest tuna during those days was caught by Kai M ller. The bluefin weighed 319 kg and took 11 hours to beat. The average weight of the tunnies caught out of Sj llands Odde was 225 kg. Fishes weighing less than 150 kg were rare.
Today there is no fishing at all for tuna in Danish waters.
In the 30 s, the bluefin invaded the resund waters as far south as the Island of Ven. Big game fishing for tuna started in resund 1939 or 1940. Most of the fishing during the war years took place from the Swedish side of the resund. Well-known Swedish tuna angler Arvid Carlander once had to cut his line as the tuna took him into Danish water, which at that time was occupied by the Germans. They fired at the Carlander-boat.
