This 21 May 2016 video from the Netherlands says about itself:
Harbour porpoise in rehabilitation center is offered live fish to test their hunting skills.
This is young harbour porpoise Nena. She beached in March 2016. At first, she was unable to swim. After a day in the rehabilitation center she could swim again. So now, a new stage in her recovery.
