Hi Gordy
There were both Coho and Chinook runs in the Simpson River and its tributaries in the late eighties early nineties. These were a result of sea ranching experiments with Chinook sponsored by the Japanese and substantial caged Coho farming in the Aysen Fiord. There was at that time a hatchery in one of the minor Simpson tributaries pumping salmon fry into the river and another trying to establish a freshwater ranching project in Lago General Carrera.
The vast majority of the Salmon farms in Chile at that time were operated by international companies who were permitted to operate in a largely unregulated way and without any real consideration to the ecological consequences. As the industry has expanded it slowly moved south where they will no doubt totally bugger up the marine and freshwater ecology in exactly the same way as they have done elsewhere on the planet. Chile is one of the biggest producers of farmed Salmon in the world, Pacific and Atlantic.

From Lewis Hinks :
Hi Gordy,
Bill's message about Chile, highlights the concerns about aquaculture escapees, introduction of non-native species, and the problems that escapees cause. There are also reports of reproducing populations of Atlantic salmon in some British Columbia rivers. At one time, for a brief period, there were reports of a self-sustaining run of Coho in a small river in Nova Scotia, believed to have originated from escapes from an aquaculture site in New England.
Non-native species populating areas is never good news. We are having real problems here in Nova Scotia with both Smallmouth Bass and Chain Pickerel. Both non-native and both considered invasive at this time.

[GH] Lewis... In almost all cases, I'm sure that is true.
We must remember, however, the apparent success of the introduction of striped bass from the Atlantic to the Pacific coast of California. While there may have been a downside to that venture, I'm not aware of it.
Then there was the original introduction of brown trout to the U.S. from Europe, years ago. One could argue the pros and cons of that one.
I know of no problems with the introduction of rainbow trout to New Zealand. Perhaps there were some.

Troy Miller weighs in :
I’m with you on the wild vs. farmed flavor preference, Gordy. Wild sockeye are my very favorite fish in the world to eat. Farmed Atlantics would rank down in the 20’s or 30’s favorite, for me. I’ve made my harvest for 2010 – all caught on traditional flyrod and fly in Alaska. They were all carefully filleted, wrapped, vacuum-sealed, and frozen to be enjoyed by my family and close friends this winter. Lord willing, we’ll do it again in 2011, 2012, 2013…
Regards,
Troy Miller ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
From Ally Gowans :
Hi Gordy,
The British records for game fish (here that means salmon and trout) are categorized broadly into natural and cultivated fish and I note that there is yet another category which is “resident”. See http://www.anglingtrust.net/page.asp?section=41
Best wishes,
Ally Gowans
