Scientists are worried about low oxygen zones in oceans ...

Scientists have expressed concern that global climate change may
be accelerating low oxygen zones in oceans with disastrous consequences for sea life in the three oceans. Sounds really depressing:
"The depletion of oxygen levels in all three oceans is striking," said Gregory Johnson , an oceanographer with the National Oceanic and Atmospheric Administration in Seattle .

In some spots, such as off the Southern California coast, oxygen levels have dropped roughly 20 percent over the past 25 years. Elsewhere, scientists say, oxygen levels might have declined by one-third over 50 years.

"The real surprise is how this has become the new norm," said Jack Barth , an oceanography professor at Oregon State University . "We are seeing it year after year."

Barth and others say the changes are consistent with current climate-change models. Previous studies have found that the oceans are becoming more acidic as they absorb more carbon dioxide and other greenhouse gases.

"If the Earth continues to warm, the expectation is we will have lower and lower oxygen levels," said Francis Chan , a marine researcher at Oregon State .

And people wonder why seafood cost so much. Supply and demand. Large demand but the fish are all dead.

Also, overfishing. It needs to be made more sustainable if you want to keep eating fish.

Thankfully not all of them. Worst part for me is that they are now farming fish, and one sometimes does not know what the difference is.

The difference is how they're raised. Trust me, I sell the stuff. Farmed and wild are, in heath terms, the same thing. Flavor is a different issue but any heath nut that rants on farmed fish is an uneducated fool tbh.

The health nuts fear that farmed fish could develop diseases, as well as unfriendly organisms. People in the health industry advise that not only is salmon from the ocean more healthy, but it has to be wild salmon.

Yes, because Samoan that isn't monitored and, when sick, medicated back to health, is so much better for you. :rolleyes:

Look, the same people that make that claim said that farmers were using dangerous vaccines to treat sick fish stocks, never mind the illness in question was bacterial and the antibiotic used proven harmless to humans.

Now in flavor wild is better. I'll not say otherwise. But these health claims are like the organic claims (no real nutritional difference) which is to say total BS. You know who benefits from all the scares? Fishermen. You know who's paying the lobbyists? Fi... Well do I really need to say it?

I'm reading your comment with great interest. As I love salmon and my favourite for taste is Atlantic Salmon. Another claim they make is that the colour of the farmed fish is usually a sickly grey/white, so they have to use additives to give them the pink colour. There are some good farmers however that use natural microbes to give the salmon its pink flesh. But the ones with the additives are in the majority?

This is true but the color is added by the feed, not some additive. Sort of like flamingos, they're supposed to be white but they eat lots of pink shrimp. Farmed (and wild) salmon eat lots of reds. Some feed is more natural then others but it's just fish food, not injected chemicals and the like.

We have fish farms where I live. I live on the coast. It's better, because it's sustainable.

What does sustainable mean in the context of fish farming and why would fish farming on the coast be more sustainable? What are you comparing it with?

Oh! No, i'm saying fish farming is sustainable - compared to overfishing natural stocks. The fact I live on the coast was more to provide context for fish farms being nearby.
