I can't make a biological case to adjust the season or lower the limit.
I do have a pretty solid handle on hunter behavior. It is correct to say that a very small percentage of hunters kill a limit. Let's group the honest guys that stop at 5 and the ones that don't, together for this discussion. Together, they make up a small percentage of those that attempt to hunt at some point during a season. If the limit was 3, the guys killing 15 would still kill 15. And unfortunately, I believe a decent group of the current "honest" limit killers, would have a hard time stopping at 3. Then once they start killing over the limit, why stop at 5?
There's more to the whole discussion, but I don't think dropping the limit from 5 to 3 would change the state's overall harvest. I actually believe it is very short sighted to think it would make a difference in harvest numbers.
Even if biological evidence supported lowering male harvest could increase poult production - lowering the limit wouldn't really be the answer anyway.
