Some rivers in Chile and Argentina have been colonized by king salmon from an ocean ranching program in 1978 to 1989. There were two hatcheries located in Southern Chile. They raised and released hundreds of thousands of chinook smolt which came from the Columbia River. They believe that farmed salmon are another possible source of the naturalized runs. The article in SEAFOOD.COM stated that these runs might become large enough to support a commercial fishery.Â
