Why dont they use returning hatchery fish opposed to taking wild fish make hatchery fish? They are made with 2 wild fish so I dont understand why not?
There are people who frequent this site far more qualified than I to answer that question, and I hope they do.
In the meantime; my take on this issue is breeding hatchery fish begins to further weaken the unknown gene pool of C-V fish; the more generations of hatchery fish returning and the subsequent breeding programs results in poorer survivals of fish that do spawn, increased competition with wild fish, and over a few generations, like what has happened in Washington, Oregon and California, truly wild fish are basically extirpated. Try Googling this subject.
Many believe there are no real wild steelhead left in the C-V, and, from a purely scientific genetic standpoint that is probably correct. However, (and this why I and a few others continue to monitor these fish) those we observe every spring in the upper river are as wild as anyone in 2016 could expect from a fish … wary and spooky as hell, males fighting for females and the territory that entails, erect dorsal and adipose fins, and basically just magnificent.
I believe the present steelhead hatchery program on the C-V needs major changes and have been advocating for that for years, but, imo, changing protocols to breed and release hatchery fish would be the beginning of the end for this system. Considering how these steelhead and this river has stood up to the pressures of urban encroachment and the huge increase in angling pressure shows just how well wild steelhead can do when they have a degree of protection, in this case a closed to angling upper river, which results in an unknown wild spawning population.
