Is this fish pining for the fjords?

When you go into fish restaurants there is usually a fish tank full of fish swimming around.  If one looks tasty, you ask for it.  The point is that you can see that the fish are fresh.  This attracts the punters.  None of your frozen rubbish.  But you don't usually see one worn out after a long squawk...

 
 I'm not sure how long ago this one had been Resting In Peace when I took this.  It was not there when we left.  I haven't been back.
