See the pictures of the dying animals that Tobias Dahlin filmed in the clip above.
Along with the sharks were also some rays, also the red-listed ones and must therefore not be taken out of the sea by the fish.
In addition, several of the animals were still alive and can be seen in the pictures gasping for oxygen, which the Deep Sea Reporter was the first to report on.
Tobias Dahlin is an underwater filmmaker and was the one who dived down and filmed the sharks after he saw about the students' findings on Facebook.
He suspects they were dumped by a fisherman.
- They are undoubtedly dumped there, everything else is excluded, says Tobias Dahlin.
Controversial issue
The question is controversial and none of the small boat fishermen or trawlers that SVT has been in contact with want to stand up for any interview.
But several of them say on the phone that it is very common to get sharks in the catch, especially for the trawlers, and that they then have to throw them back into the sea because they are not allowed to pick it up.
And Tobias Dahlin believes that this is animal cruelty and would never have been allowed if it was about terrestrial animals.
- The sea surface is a barrier.
What is going on down there does not see ordinary people, then this can continue.
Much of it could never have continued if it happened on land, says Tobias Dahlin underwater filmmaker.
According to the Swedish Maritime Administration, protected species must be restored immediately.
