I'm with Ya here too LT. There are probably a number of methods the commercials could use to selectively fish and do so more effectively and economically. Fish wheels, traps, purse seine. I think it was Salmo g. who mentioned, why not have the fish ladders on the dams lead to sorting ponds where the fish are selectively harvested, great idea!

Unfortunately I think the commercials and tribes would balk at this. Too unmanly, they need the wind in their hair as they race in their boats loaded with nets to their secret "honey holes". You know, heritage. It would also take the competition out of commercial harvest, like OK guys line up and here's your share, too much like welfare, which I'm sure some would argue commercial fishing all ready is.
