Iceland has been in the headlines lately -- and not because of fishing. Instead, it's the country's fledgling Atlantic salmon farming sector that is dominating the news.

It is not the first time Iceland is trying its luck with salmon farming. Previous attempts have failed, but technological developments, warming waters, a favorable biological environment, and not least the recent flurry of Norwegian investment is testimony for many that this "third wave" of salmon farming could be a success.

Predictions on how big the sector can actually grow vary widely.
