I agree that harvest through the ice is the biggest threat to our poulations of quality bass, especially on the smaller bodies of water. Ice fisherman usually fish in groups and "6 per man" can add up pretty quickly.
I would fully support the idea you set forth and would be happy to work with you in having the DEP consider your recommendation. Please contact me if you would like any help in this regard.
And yes, I DO think a creel limit would help. I could have legally kept hundreds of bass this year if I wanted to, but I put them back so that my son, the guy down the street and I can have the thrill of maybe catching them again when they are bigger.
