I don't see how all the commercial (and tribal) fishermen that currently fish for Columbia River fish are ALL going to be able to do this. Who gets to put traps where? How do the traps upstream keep from getting "low holed" by traps directly below them? How many traps will it take to effectively catch fish? Are they willing to put the same effort into killing off all other means of commercial fishing as they are in killing opportunities for recreational fishing(which has a MUCH lower mortality rate on released fish)? Is it effective enough to remove all hatchery fish (or at least most of them) without other ways? I think it's a good thing if at all feasible in terms of practical applications. As a reasonable person I tend to believe that it won't impact the efforts to curtail opportunities for recreational fisherfolk by WFC as we are the lowest hanging fruit they can reach . Bob R
