The tuna which has been absent from the Öresund area for many years is starting to reappear according to countings done by Danish and Swedish researchers.
New regulations and better controlling introduced 15 years ago are thus providing results and in combination with an increased amount of the fish species that the tuna feeds on, the tuna stock is now replenishing.
During 2022 the researchers tagged 48 tuna individuals in order to better track their movements for future research.
