Apparently they are doing pretty good around my area lately,running big nets in the river and scooping them up, returning the natives to the water and selling them for animal food, and the river hasnt been as bad as it used to where I live....went out the other day and they arent flying everywhere like they used to, when I say used to I mean by the hundreds jumping at your boat, now your only getting maybe 100 or so within a 5 mile stretch, so there is some improvement. Talked to DNR around here and they say said they are giving it there best efforts, and it actually looks like it might actually be paying off!
