Nutritionally, wild salmon is a much better choice compared to farmed salmon. I don't see the article addressing this issue. I would love to see the brand highlight their nutritional profile vs other farmed salmon. Eating more of this farmed salmon is generally an improvement for a typical diet. However, for example -- the company on their FB page looks to use "Skretting" feed. Skretting is not a bad choice, but it is not the same as the salmon's diet in the wild: https://www.skretting.com/en-us/transparency-and-trust/faqs/what-ingredients-are-in-skretting-feed/ https://www.skretting.com/en-us/transparency-and-trust/faqs/... I wonder if they add dye for color. I do see some positives in "LocalCoho ... are never given antibiotics, growth hormones, or pesticides" from https://www.freshdirect.com/meat_seafood/sea/sea_salm/sc/salm_pac/p/sea_pid_3604203 https://www.freshdirect.com/meat_seafood/sea/sea_salm/sc/sal... Though generally looking into more interviews (ie, : https://www.todaysfarmedfish.org/meet-your-fish-farmer-1/coho-salmon-at-finger-lakes-fish https://www.todaysfarmedfish.org/meet-your-fish-farmer-1/coh... ) and content they've put out, the quality control for their facilities seems high compared to others I've seen in the industry.

It’s also actually better for the environment, in that wild salmon sustainability is inextricably entangled with environment health. If things aren’t just so, the runs don’t run, and it’s lose-lose.

  I would encourage you to look through some of the studies published on this at Google Scholar: https://scholar.google.com/scholar?hl=en&as_sdt=0%2C34&q=farmed+vs+wild+salmon&btnG= https://scholar.google.com/scholar?hl=en&as_sdt=0%2C34&q=far... They are both fish, so you're not going to see vast differences like between Twinkies and salmon, but macro-nutritional information doesn't tell the whole story.

  I will paste a few of the abstracts here: Levels of omega-3 (n-3) and omega-6 (n-6) fatty acids and lipid-adjusted concentrations of polychlorinated biphenyls (PCBs), dioxins, toxaphene, and dieldrin were determined in 459 farmed Atlantic salmon, 135 wild Pacific salmon, and 144 supermarket farmed Atlantic salmon fillets purchased in 16 cities in North America and Europe. These were the same fish previously used for measurement of organohalogen contaminants. Farmed salmon had greater levels of total lipid (average 16.6%) than wild salmon (average 6.4%). The n-3 to n-6 ratio was about 10 in wild salmon and 3−4 in farmed salmon. The supermarket samples were similar to the farmed salmon from the same region. Lipid-adjusted contaminant levels were significantly higher in farmed Atlantic salmon than those in wild Pacific salmon (F = 7.27, P = 0.0089 for toxaphene; F = 15.39, P = 0.0002 for dioxin; F ≥ 21.31, P < 0.0001 for dieldrin and PCBs, with df = (1,64) for all). Levels of total lipid were in the range of 30−40% in the fish oil/fish meal that is fed to farmed salmon. Salmon, especially farmed salmon, are a good source of healthy n-3 fatty acids, but they also contain high concentrations of organochlorine compounds such as PCBs, dioxins, and chlorinated pesticides. The presence of these contaminants may reduce the net health benefits derived from the consumption of farmed salmon, despite the presence of the high level of n-3 fatty acids in these fish. This pilot study examined five commercial salmon feeds, four farmed salmon (one Atlantic, three chinooks) and four wild salmon (one chinook, one chum, two sockeyes) from the Pacific Coast for PCBs (112 congeners), polybrominated diphenylethers (PBDEs – 41 congeners), 25 organochlorine pesticides (OPs), 20 polycyclic aromatic hydrocarbons (PAHs), and methyl and inorganic mercury. The farmed salmon showed consistently higher levels of PCBs, PBDEs, OPs (except toxaphene) than the wild salmon. The mean concentrations in pg/g were 51,216 vs 5302 for total PCBs; 2668 vs 178 for total PBDEs; 41,796 vs 12,164 for total OPs (except toxaphene). The farmed salmon levels are likely a consequence of the elevated level of contamination found in the commercial salmon feed (mean concentrations in pg/g were 65,535 for total PCBs; 1889 for total BPDEs; 48,124 for total OPs except toxaphene). Except for a single high wild chinook value, PAHs were highest in the feed samples followed by the farmed fish and the three other wild fish. The Bio-Oregon-1996 feed of hatchery origin showed a level of PAHs ten times higher than any other feed. The genotoxic implications of such a high PAH level are considered for juvenile chinook salmon. Toxaphene and methyl mercury concentrations were not notably different between the wild and farmed salmon. There was no clear low contaminant brand of salmon feed. The human health implications of eating farmed salmon are considered from the perspective of the current WHO and Health Canada (2000) tolerable daily intake (TDI) values for PCBs. Based on a TDI of 1 pg TEQ/kg bw/day, this analysis indicated a safety concern for individuals who on a regular weekly basis consume farmed salmon produced from contaminated feed.

> wild salmon is a much better choice compared to farmed salmon there are these believes that wild salmon has more mercury and other toxic stuff.
