I have no idea, I know I have been fishing a few times and had someone ask me if I was aware of a change and I was, and I have mentioned things to others as well hoping to help them steer clear
The “game wardens” here are sworn officers of the state troopers and are generally decent folks unless someone goes out of their way to be an *a-hole and then they can get really hard really fast
I have seen slob hunters and fishermen bragging about limit violations and shenanigans and the word ripples up or down the river and magically a brown shirt trooper appears and wants an explanation of the triple limit of fish in the cooler
Law abiding sportsmen hate slobs because they *f-word it up for everyone
It is generally fish limits or times or locations that can change rapidly due to low or even high count numbers and in popular spots they will post updates and changes on campground bulletin boards etc, but regardless it’s on you to be aware
