Fish farming is now the world's fastest growing sector of animal production, and salmon and trout form the mainstay of Britain and Europe's 'aquaculture' industry, with further species such as cod, halibut and turbot being added to the list as wild populations crash due to overfishing.
Cod farming is causing a wave of interest, not least because of the decline in the wild cod population.
Farmed fish are fed on wild fish in the form of fish meal: more than 3 tonnes of wild-caught fish are needed to produce 1 tonne of farmed salmon.
