Rising bottom temperatures have lured many new fish species, particularly sharks, to Öresund, the narrow strait separating southern Sweden from Denmark, a local news site reports.
A fisherman from Hornbæk on northern Zealand recently reported finding no less than 26 sharks trapped in his nets.
“These waters are actually teeming with sharks”, a biologist with a local aquarium was quoted as saying, adding reassuringly that none of the species sighted formed a threat to humans.
Shark species reported recently in Öresund included spiny dogfish, school shark and houndshark, but also exotic fish such as John Dory and the Eledone octopus have been caught, otherwise common in the Mediterranean.
