i recently was talking to someone about the salmon hatchery's and how much he thought they benefited the environment and ecosystem as well as the anglers who fish for them he gave me a point that i had never heard before but actually made a lot of sense:
he said that the hatchery's bred fish that were not as well suited to being in the wild as wild fish and that the hatchery fish were genetically weaker than the wild fish so when they accidentally mate they would make the gene pool a bit weaker
his last point was that hatchery's will sometimes give entire populations sicknesses and still release them which make the wild fish sick as well, he gave me an example for that, the Alsea river coho. back in the 1990's i think they had a coho hatchery on the Alsea which accidentally put a disease in all of there fish yet still released them out into the river killing the wild population as well when that run came back in they found that only 10 coho had spawned that year and so they removed the hatchery, he used that example to point out that coho have been thriving in the Alsea even with no stocking them, and monitoring there population
so my question to all of you is did i miss some data, do you agree with his analysis of Oregon's fish hatchery's and what do you, the fisherman who probably know quite a lot about the ecosystem think would be a better way to take care of the salmonid population's in oregon
