Don't forget glow in the dark sea food ala Fukishima from the Pacific areas.

As an aside a rock star named Ian Anderson (Jethro Tull front man) had salmon farms for many years and did a lot to improve the final product and the lives of the fish, but he ultimately got out of the business due to economic restraints caused by other salmon farmers.

Most or all farmed salmon processing houses add food color so that their fish doesn’t look anemic.

There is also a lot of efforts to re-stock streams, lakes, rivers, etc, plus there are efforts to restore means of salmon to naturally make it past dams to spawn.

Plus there is the damage to fresh water spawning fish and bottom feeders such as the tuna you mentioned due to pollutants in the water.

It will take increased conservation efforts on all fronts to sustain human consumption. I dunno if other countries are as vigorous in their efforts at this as is the USA. IMO not enough is being done about the pollution of water ways.

But as I noted (above), nothing will reduce the consumption of sea food. It is another example of the human eco system consuming and destroying nearly everything around us, not unlike an over grown bacteria in a petri dish; and probably with the same end result.

I said 'net loss' because of the losses of by catch and spoilage involved in securing a large amount of sea food for farmed salmon. That and the disease and parasites that farmed salmon 'cultivate' to the detriment of the wild species. Not to mention the necessity of fossil fuels to go out and catch that seafood, while wild salmon do that work on their own.

I read about Ian Anderson and salmon farming years ago when it still sounded like a good idea and I've wondered more than once what became of him.

Not sure but I think the anemic looking color of farmed salmon has something to do with not getting something in the wild diet that imparts that color. But yeah, that is a bit weird that color needs to be added to make it look appetizing.

None of this is soothing, it's looking more and more like we humans will indeed play out a sort of rabbits on an island with no predators scenario. When the hordes of people living near the coasts begin to come up seriously short in their seafood haul, which I gather is already happening, they'll be looking further inland for food, taxing those resources as well.

Thanks for explaining. I was thinking along different lines, including the cost, which so far is not a loss for most salmon farmers anyway, and also the natural life cycle of salmon.You’d think if farmers were serious, they would set up support farms to grow and harvest food that farmed salmon eat.

He continues to do very well for himself. Sold the salmon farm some time ago and continues to be a touring rock star and producing new recordings about every other year. He’s a phenomenal musician and a heck of a business person.

Iirc the color is thought to be due to the lack of shrimp and related food in farmed fish diet. I guess they do much the same to beef – which is to say that red dye is added to make the meat look red, I guess. I’m not much for beef and don’t keep up.

And then we learn of things such as some rabbits digging a gold mine that will dump toxins by the metric ton into Bristol Bay, where some claim up to 15 million salmon were caught per year. Editorial: Save Bristol Bay, stop the mine | Editorials | The Seattle Times

I guess one way to reduce over fishing in the area is to simply kill off the fish…
