Maybe this is the future https://www.science.org/content/article/oceans-away-raising-...

Technically it works. Superior Fresh, as in the linked article, has a viable system. The challenge is that in the beginning it is hard to reach a scale that works economically. Added to that, in Norway it is challenging to grow leafy greens in greenhouses in the winter, compared to the latitude where Superior Fresh is located. It can be done, but is energy intensive. We ran a fully indoor pilot facility for five year…

The article does not mention land-based fish farms but instead the "egg", a more enclosed pen that is underwater but estimate that it is 10 times the cost of a pen. How would a land-based fish farm would compare economically to those innovative underwater sea pens in your seemingly educated opinion ?

Astaxanthin for the color fair. What about the salmon is bad for pregnant women?

> Astaxanthin for the color fair. Why is it fair? Wild salmon also consume astaxanthin. It’s like complaining that the farmers are bad for trying to mimic the fish’s natural diet.

I dont know what the fuck u r talking bout.

I am surprised by the statement "Today, salmon sushi is a staple of Japanese cuisine" While in Japan a few years ago, I found no salmon on the menu in sushi places. When inquiring why, we were told that salmon is not that good, and that is more a food for kids than adults. Did it change or are we just one data point?

I remember asking a Japanese chef in Japan, in 2019, and the answer I got was that sushi is much less popular in Japan than believed outside of Japan, and a lot more people eat rice and chicken, pork, etc., than salmon.

It's hard to say, depending on how far back your idea of "a few years ago" might be or where exactly you ate. After all, Japan has a lot of sushi restaurants and even different sushi styles. For example, you definitely wouldn't find salmon in an edomae sushi restaurant. For reference, salmon was the most popular choice in conveyor belt sushi places 3 years ago. https://www.nippon.com/en/japan-data/h01627/

Ah, interesting stats, specially the second part when they say what type of sushi they refrain from eating. I guess that ōtoro and chūtoro is due to price. And uni... Maybe because of the flavor? It can be a bit of an acquired taste...

Recently there has been a push to farm "dry-land" salmon. In other words, the salmon live in large tanks on land, rather than in pens in the sea. At the moment a company is trying to start one of these close to me. Some local people are opposed, some are supportive, but most just want more objective study and information (i.e. not performed/paid for by the company itself). The devil may be in the implementation, but…

I'm no expert but that seems like it could be very energy intensive. All the systems to maintain water quality, temperature. Not to mention the problems that arise having fish in such high density. There are other places in the world that farm salmon at a much lower density which helps in terms of disease and bioload on the environment. There's a company in New Zealand attempting to build open ocean fish pens, they m…

Energy may not be so much of an issue here in Quebec, where electricity is USD$0.05/kWh (residential rate) and 99%+ of it comes from hydroelectric power.

Salmon feed lots, with a similar problem of concentrated waste, cruelty and unhealthy animals. Sounds like the underwater egg solution they discuss in the article might also be solving an optics issue they have. Out of sight, out of mind.

Two salmons can feed 5000 men. At least that’s the belief 20% of the US population has.

1. The Title should be "Norway became a global salmon behemoth. Now it's facing the consequences". It fits the character limit, why change it? 2. A lot of the conditions for Salmon farming can be drastically improved or completely eliminated if they have done it further away in deep sea rather than coast. It just cost more. 3. China is rapidly improving their Salmon Farming so there isn't much to worry about for Norw…

Points 2 and 3 kind of contradict themselves though, as China doesn't have access to deep sea (at least until the invasion of Taiwan or if China manage to take control of their claimed share of South China Sea).

You can farm fish outside territorial and exclusive economic zone waters. But in any event China has substantial EEZ waters: https://www.marineregions.org/gazetteer.php?p=details&id=848... Taiwan isn't much of a hindrance. For one thing, the Strait is 100 miles wide. And China's coast is much, much longer than Taiwan.

Growth hormones. It’s better now than some years ago, but still. Some claim the do not use them at all. And they use a lot of antibiotics. And there is some accumulation of dioxins and PCBs in the fat due to the feed, but this has also been approved somewhat.

Compared to most other meat production farmed salmon does not use a lot of antibiotics

I think this is a veiled advertisement for Norway. Half of the world is engulfed in wars and terror (half across the road towards Mad Max), however Norway is worrying about the environmental effect of salmon feces on its fjords.

Eh foreign correspondent stuff like this tends to release at the end of a long pipeline. They spent 12 months on a piece on Israel that was focusing on the conditions of Palestinians near Israeli settlements in the West Bank, and it dropped a couple weeks after October 7, you could tell that they were pissed that it wasn't about Gaza, but were still happy to be in roughly the correct ballpark.

There other arm, 4Corners, did a piece about a big government construction project and IIRC there was a different prime minister when it released vs when they started the investigation.

I think you meant tuna not salmon. A large tuna can be 100's of kilograms, whereas a large salmon you are lucky if there is 10kg of edible meat
