Yes, it is discussed here.
It has been identified as some sort of Chimaera monstrosa, or ratfish.

It was one of our cryptozoology students who reported this to GUST and a local newspaper broke the news: "When Karin and Kenneth Palmqvist was half way through their bonus pack with frozen shrimps they found a strange animal. The creature reassembled a crocodile with large upper eyes, behind the head and the gills are two fins that look like they are developing into tiny legs".
