rays in Scandinavia

Uppdaterad: jul 16

And the threats they are facing...

These are egg-cases from a Thornback ray. As all other rays in the North sea, Thornback rays are extremly endangered in Sweden. Commercial fisheries have almost wiped out all of them.


When it comes to rays; when they are about 1 year old, they have grown big enough to get cought in a trawler. And this is unfortunatuly what happens to most of them. The ones that survive must wait 10 more years before they are ready to reproduce for the first time.


10 years... that is a long time to avoid a trawler. Almost impossible.


As most rays in the North Sea, Thornback rays lives on the ocean floor where they feed on shrimps and other crustaceans. Obviously, this means problem when the people of Europe want to eat shrimp and crayfish.


This also shows the problems with certifications like MSC (Marine Stewardship Council).


Certifications like the MSC have certified more and more trawlers in the North Sea the last couple of years. It's hard to understand how a trawler can be sustainable enough to get a certification like this. Even if the North Sea shrimp and crayfish are not endangered, the method to fish them (Trawling) is catching everything in its path. Also endangered fish like rays and sharks.


So ''Sustainable fished'' shrimp and crayfish are killing extremly endangered sharks and rays.


At least 30 species of sharks and rays used to be found along the Skagerack coast. Now almost no sharks or rays can be find at all. So far.. I've only encountered dead ones.
