Norway produced instead 1,3 million tons of salmon in 2012 (and growing). Is the first european productor and by far the largest (Spain is the second with about 260.000 tons/year of mussels). Their aquaculture industry is an strategic sector for this 'small' (in terms of population) nation.
Is interesting how Norway won against the huge japan pride focusing in improving the visibility in supermarkets and targetting people that wanted cheap food. Realizing that to target first the higher social classes was a lost battle from the start.
Than being said, prices are now crazy low in Austria compared to what they were a few years ago.
Aquaculture fishes instead do not have problems to obtain fat. Fat is cheaper than protein so you have better cost-benefit ratio if you feed your salmons with more fat content pellets.
I'm not saying that the farmed salmon is a bad product at all but wild salmon is a different thing. Not so apt to freeze and send to thousands of Km. You can earn more money selling it in fresh in the local market as wild product (but be aware that some 'wild' high-prized salmon in the market is farmed probably in fact).
NB I am in Scotland and eat a fair bit of salmon and I wasn't aware of the "line caught" label.
Edit: And by "extremely expensive" I mean up to £10,000 a fish.
Not easy to know, but many could be imported from Denmark probably, scottish and faroese salmons are in the same population.
> Fishing in Scotland can be extremely expensive
The NASCO headquarters are in Edinburgh in fact. Is a measure to try to recover the species. To fish the genetically better specimens just a week before to spawn is a silly move (you are killing millions of fingerlings).
Americans are also worried about the US fisheries and concerned about the need to preserve the resource. All atlantic salmon in the US market is farm-raised.
