In the experiments with freshwater fertilization the general response is that salmon that rear for a year or more (coho and sockeye) respond almost immediately. In most cases, mykiss (resident and anadromous) have taken years to show a response in the adults. The Keogh had a immediate response in the rearing juveniles and this did result in a jump in adult returns.

So, it appears that mykiss has more controllers than the salmon. I agree with Drifter that we are decades out with meaningful wild anadromous mykiss recovery. That is, if we really are serious about mykiss recovery.
