Seems strange to me to have a season and rules. Short period of time, have to have a fishing license and permit to do it, not allowed to move any rocks or debris, has to be male only, over 40", and harvest limit of one!!! He and his son enjoy it, and said their best weekend was 150!!! YIKES.
Cool snake and pic.
There are various laws and regulations concerning both venomous and non-venomous snakes in quite a few States.
In PA. you must have a license to possess, collect, handle, kill....the Timber Ratter and Copperhead (both have seasons).
A tag to fill out and a report form to send in also.
Other restrictions apply, (total length, sex, number in possession, etc).
