The salt draws out the excess water in the oven. I'm not sure you can call it cooked, its more just warmed up. If it starts to cook, it turns to slime. Bloody tricky.

In Norway they have http://en.wikipedia.org/wiki/Rakfisk. I seem to remember a rotten fish dish you buy tinned in Sweden. The gas build upo in the tin being so bad, it recomended you open the tin under water.

you're prob right, heated not cooked.

The tinned fish is surströmming (literal translation, sour/rotten herring). I've never tried it as it's not local to where i'm from, but speaking to people they other love or hate it. Someone compared it to Stinking Bishop, ie harsh smell mellow flavour, and if that's true I might like it, really liked the stinkin bishop.

Never heard of Rakfisk. Looks tasty though. Have you tried it?
