walleyebob -- remind me: why do we want to trap perch? (obviously, I missed or didn't read something...).
Again, as Fshrmn has mentioned numerous times -- adding more fish (prey) is not the answer. Reducing, or keeping in check, the number of predators is. Harvesting walleye and pike at Yuba will only HELP the fishery. It may be a tough concept to swallow and understand -- but by removing fish you will be keeping the population in that range of fast growth -- which is ideal. Take a look at the attached document, specifically page 10. The graph shows you that ideally you want to be in the range of maximum population growth. If you are not harvesting those predators, you very quickly jump up to the top of the graph where there are lots of fish, and very slow growth -- which means few large fish. Harvesting the walleye and pike will help keep the population at a healthy state, and maximize potential.
