ArtCarney, thanks for the information/input. I think the idea of having a large cast net with a winch to haul them in after shocking would be the best if we could get there. Yep, the electro shocking may require some type of training and certification, but I agree this is the way to go for fish below the dams. They are there in huge numbers as far as I know and would eliminate a pile of potential fish getting through the 'Trial' barrier that is planned. The barrier if it works does not reduce the fish numbers, just keeps them away from an area based on what I read. We need to remove them, not scare them off.
