Wild salmon range in colour from pink to robust red. Their colour comes from a natural diet rich in red-coloured krill
Farmed salmon feed includes fish meal, fish oil (from sardines, herring, anchovies) poultry byproducts (such as feathers, necks, intestines) and GMO soy and canola. The result is farmed fish with pale gray flesh. Dyes are added to their feed to give farmed salmon an attractive colour. The SalmoFanTM is used to measure the optimal shade of pink for farmed salmon. Tests have shown consumers prefer (color No. 33) a deeper shade of pink.
Wild Salmon travel 1000s of miles across the North Pacific Ocean, maturing in the natural ocean environment, before returning to their natal rivers to spawn
Farmed salmon are confined to open net-cages. Problems with ocean net cages include sea lice, diseases, antibiotics, chemical treatments, pollution, algae blooms, fish feed, farm waste, marine debris, and marine mammal deaths.
Wild salmon are antibiotic free
Net-cage salmon farming encourages antibiotic use. A salmon farm with 200,000 fish releases fecal matter roughly equal to a city of 65,000 people. In crowded net pens, diseases and parasites can become epidemics.
Wild salmon are GMO free. They graze on wild food in the open ocean
The Norwegian Food Safety Authority recently stopped approving eight GMOs for use in fish feed because they contain genes for antibiotic resistance. Eleven other GMOs are still permitted in Norwegian fish feed.
Genetically modified farmed Atlantic salmon
The US Food and Drug Administration is reviewing whether to approve a genetically modified Atlantic salmon that grows twice as fast as normal. These genetically modified Atlantic salmon are designed for the farmed salmon industry. If approved, they would be the first genetically engineered animal for human consumption.
