Fish Farming - Misc

For every kilogram of farmed salmon, it takes between 1.8 to 4.7 kilos of protein pellets. These pellets are made from other fish. In Canada it is illegal to feed fish with food that humans could eat, so the farms ship fish protein in from developing countries with lower food standards. This means that the poorer people there have a harder time getting fish, a vital source of protein for them. This is referred to as "Global Protein Loss."

The majority of salmon farmed here in BC are Atlantic salmon. Atlantic salmon are more susceptible to sea lice than Pacific salmon. Normally, they aren't a major problem, as Pacific salmon are able to resist them. However, sea lice thrive in the pens of the less resistant Atlantic salmon, and reproduce in great numbers. These populations then spill into the ocean and cause significant detriment to the wild stocks.
