Salmon, Atlantic (Farmed)
Production country — Europe
Production method — Open net pen, GlobalGAP certification
Salmon are farmed in open net pens in the sea. Producing fish in open systems can cause environmental impacts such as: impacts of chemical and sea lice treatment usage; nutrient and organic waste deposition; outbreaks of disease; impacts on wild salmonids by transmission of sea lice, and escapes from farms. Salmon are carnivorous fish and rely on wild capture fisheries to produce their feed, MCS would like to see all these fish certified as sustainably managed. Due to the ongoing nature of as yet unresolved environmental impacts of salmon farming MCS is advocating a halt in industry expansion until these can be resolved.

Salmon are termed “anadromous”, meaning during their lifecycle they move between fresh and marine waters; salmon farming attempts to mirror this lifecycle. Broodstock fish are moved to freshwater for spawning, where the eggs are also fertilised and hatched. The hatched fish (called fry) are also kept in freshwater and fed pellets manufactured from fish meal. At about 18 months the fish (now called smolts) are transferred to seawater cages where growth continues until market size is reached, usually at about 2 years.
