That is... unintuitive. Wouldn't the escaped salmon have to be able to get back upstream enough to where the wild salmon are laying/milting?
They’ve bred more docile salmon, according to the article. Getting that DNA into wild populations would be problematic I’d imagine.

That’s not what “a hamburger” consists of for most of the population. I’d guess That makes “a hamburger is healthier than salmon” wildly incorrect as a generic statement.
Respectfully, allow me to make subtle, but not insubstantial correction: "“a hamburger is healthier than salmon”" to “a hamburger is healthier than farm raised salmon” That holds closer to the actual context. I admit, the ultimate truth of whether a burger is technically healthier than farm raised salmon, is questionable. In my opinion, in either direction, but will concede that. That said, had the parent stated that…
I live in Norway and me and my family do not eat farmed fish - for multiple reasons; political, ecological, animal cruelty etc. A hamburger probably has a better nutritional value than farmed salmon. Children and pregnant women should also limit the intake because it can disrupt development. And the color is fake, if they do not add coloring to the feed, farmed salmon would be gray. I could go on the whole day about…
Do farm raised fish still have elevated heavy metal levels? I figured that getting human controlled food would cut down on that.

Absolutely valid to attack the political beliefs here. Farmed fish is somehow considered ecologically harmful but it's significantly less harmful than overfishing and allows for bringing extremely efficient, healthy food to the continental interior, which has the potential to reduce heart disease without medication. It's so narrow-minded to treat farmed fish as some moral failing.
Sushi in the middle of the desert (for example in Las Vegas) is and has never been ecological sustainable.
Would not feed it to my worst enemy.
If can afford wild then get wild, otherwise farmed is cheaper.
No different to farmed animals or non organic crops. All three are maximised for growth rate and revenue

Predators trying to eat you alive all the time, cannibalism, diseases making tunnels in your muscle, famine, acid water, contamination, environmental changes, noise levels that could make you crazy. If you have luck you reproduce once and then die of exhaustion and skin infections. If not, a bear eats you alive just when you were thinking in losing your virginity at 40 Yo, finally. Or a fishermen puts a hook in your eye, or in the mouth just for fun, pulls you out of the water and lets you suffocate slowly. Or you bang your head against a concrete wall. This is the normal journey of a wild salmon.
And this is NOT animal cruelty. This does not make you sad.
If you are on a crusade to remove animal cruelty, look at all this people living in Tokyo. They are packed like sardines in a can. But humans are gregarious animals, so it does not matter!. (They are happy!). Salmons on the other way are gregarious animals, so it is a big problem!. (They are sad!. They talk to me complaining!)
Is a problem, simply because it does not fit into our ideological vision of the world. An infantile paradise where salmons are nice little people with tiny hats that party with Pepa pig. They love bananas, football and to climb trees. (They must love it, because we do).
The idea that salmons are predatory fishes and would not mind to eat their siblings if they can catch them... don't like that. Protect me from the real world, pikachu.
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…

> likely to have a strong or far-reaching effect; radical and extreme: a drastic reduction of staffing levels.
Strange to have an article about salmon farming drawbacks without mentioning escaped salmons polluting the wild salmon population. There has been a strong decrease in wild salmon as they lose the ability to migrate back up the river to lay their eggs due to breeding with escaped farming salmon.
I suppose natural selection will act on those salmon that can't reproduce.
Similar approach works very well ie on tse-tse fly in parts of eastern Africa I've visited - introduce infertile/weak males into wilderness to effectively eliminate entire population in medium term.

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

Hmm… that made me think of domestication, do you think we could ever have salmon as pets? What’s their character like? More like dogs or cats?
