A couple of questions about the on land salmon farms. Does not the sea water return to the nearby body of water? If so, is there not contamination of this water?

In my mind the farm raised salmon do not have the same texture as the "wild" salmon--probably due to the more use of muscle tissue in the wild salmon. Any comment on that issue? (It has been noted in other species).

There seem to be more healthy levels of Omega 3 in the Wild salmon.

Thanks.

From what I know of only one on land farm, the waste is collected, filtered from the water and composted. I believe the water was recycled, but don't know the particulars.

I suspect that the Omega3 might be less because the feed for the farmed salmon is geared more towards protein than fat, with added color components.

Harvey,
The Protein is about the same in the Wild vs farmed, but the fat is higher in the farmed (according to one source at least). (and gives the farmed more calories)

Of course the color is given by the Krill which the wild eat, so the farm raised have to be fed a dye.

Here is a link to Alexandra Morton's blog.

http://alexandramorton.typepad.com/

Alexandra has written extensively about her attempts to stop fish farms in Canada. When she was younger, she studied the Orca whales in the Broughton Islands area. Then the fish farms moved in and drove the whales away with loud underwater noise designed to scare seals away from the pens. Alexandra then started studying the fish farms.

Here is a link to a post about farmed fish's influence on human health, from her blog.

http://alexandramorton.typepad.com/guide_to_safe_salmon/

A friend of mine was born in and has lived in the Broughtons his whole life. He says that the wild salmon began to decline when the fish farms moved in. The wild salmon populations have declined steadily ever since the 1990's. Greed for profit is destroying a food resource that has fed humans, bears, eagles, crabs, prawns, seals, and trees for over 10,000 years.

Very bad idea with clear consequences.

Sea lice infest pen salmon with virus's.

Sea Lice die in fresh water, however they thrive is a pen with multiple targets swimming around.

Natures plan is the correct blueprint.

I worked for a division of Campbell Soup for ten years in the DomSea division. We raised Coho salmon and some Kings in the early years.
We had two large fresh water sites in Rochester Washington and three net pen sites in Puget Sound.
My job was to build and maintain the freshwater sites. Our hatcheries were capable of holding around twenty million eggs.
After the second generation of fish we had our own brood stock that we took the eggs from.
Our smolts were transferred from from fresh water to salt water when they reached about 100 grams in size. We photo adjusted the fish by raising them in a light controlled environment so they would smolt when we needed so we could ship fish year round, not just around the summer solstice.
In the 1980's all fish farms used single pass water that we sent through three settling ponds. Now the farms recycle 90 percent or more of their water.
Our net pens were located between Bainbridge Island and Manchester in Puget sound, this is a high current area. I dove many times to rest cables and anchors on these pens. It was cleaner under these pens than under any city dock on the sound.
The feed was made to our speck using crab and cray fish shells to get the "natural" color.
Correctly done there is nothing wrong with fish farming. Over crowding and poor location along with greed are the real culprits.
I left the industry when Campbell soup sold out to a Norwegian company
Global Aqua in 1989. I still know several people in the industry.
Campbell soup was a great company to work for and were VERY environmentally conscious.

Hi Larry,

It was good to see you two at the SBS CBGT. Sorry we didn't get to visit more.

Thanks for your insight on the fish farms. Interesting. I keep wondering why the Norwegians aren't doing their fish farming at home. Nothing against the Norwegians, just the fish farm tactics, I guess.

Interesting article, thanks for posting.

I don't think any of the positives in the article apply to the Norwegian farms in BC Canada, except the reduction in forage fish used as feed. Question is, what are the farms replacing the fish used in feed with? It would be interesting to see the actual ingredients used in fish feed.

If I had the decision it would be a solid NO to using pens anywhere native stocks reside.

Worrying about overfishing may be missing the herd of Argentinosaurs in the room. Overpopulation seems to be the looming problem. Of course, Argentinosaurus is now extinct. There's probably a lesson there somewhere.

Certainly true in many lakes that have Kokanee, overpopulation only stunts growth.

Always hard to know the truth--probably even harder now with the internet. I am not directing this comment toward any one article, or way of thinking--because I don't really know the truth.

Many years ago, I was seated next to the Long Beach Ca. Press Telegraam's science editor. He had written some articles which were factually incorrect. I asked him why he wrote what he did. Answer " My job is to sell newspaper, not always to tell the truth."

People have views to peddle. I think in the Salmon fisheries there is some of that on both sides. I do know that salmon is good for you. I know that I really enjoy a good fresh caught fish, better than any I get at the fish market.

As for over population and food--currently there is more of a distribution problem, than a food shortage. Many populations are shrinking--especially in first world countries. There is concern that population will keep up with demands for workers--in some areas.

Like Bob, I don't profess to know the truth. But that doesn't mean the truth is unknowable. When I read Tamar Haspel's Seattle Times article I was struck by its one-sidedness. There is no one quoted in the article from the anti-fish farming side of the argument—such as Alexandra Morton, for example—only enthusiastic supporters of just how far fish farming has come, by golly.

There are no reader comments at the bottom of the story, and all we have to go on is what Tamar Haspel tells us. So, we need to find out a little more about her and about how impartial her reporting is. The editors at The Times should have done that before printing the article. But they have busy jobs and it's a lot of work getting a paper out every day. The good news is that with the magic of Google we can do some of the editors' work for them.

I want to emphasize, again, that I don't know the truth here. But the lack of balanced reporting in this story made me smell ... something fishy. A very quick search on Tamar Haspel's name found the following two stories (c'mon Times editors, do your homework):

From TruthWiki: Tamar Haspel – Washington Post columnist

And from Natural News: Meet the sleazy Monsanto operatives pretending to be journalists for Discover, Slate, The Washington Post and the New York Times

I would like to hear a more diverse range of opinions weighing in on Ms. Haspel's Times story, and will attempt to share this information with Alexandra Morton and the authors of the two critical articles mentioned above. It's not too late to go to the comments section at the bottom of The Times story and present a different viewpoint.

Lord, here's one Ms. Haspel wrote for The Seattle Times in 2013:

In taste test, farmed salmon beat wild salmon, hands down

Question is, who ran the taste test, and what were they smoking?
