A couple weeks ago I actually saw this happen for the first time(instead of just seeing the aftermath...). Two guys were fishing off a bridge and instead of walking the fish along the shoreline, netting it, or whatever they just swung the fish out of the water and smack right on the concrete. After letting the fish sit there for a while they finally unhooked it and chucked it into the woods. I saw them do this to maybe 4 fish, but who knows how many they killed before my brother and I arrived. I shook my head at the one guy and he just replied "raccoon food." After I told him it was illegal he just kinda gave me a smirk and went about his business and kept doing it.
The next day I fished the same waterway(though at a different location) and ran into a PFBC officer. I gave him all the info I had on the incident, which included pics and license plate numbers, and he said it was very helpful and he seemed anxious to find these people. He told me a lot of other people have reported the same types of acts, but nobody ever seems to get any important info(type of vehicle, pics, etc..) to give to the PFBC. I gave him all my info but I haven't heard anything back yet......
If you guys see this happen, get some evidence! Or better yet if you have a cell phone report them! Unfortunately I didn't have mine at the time, I was so mad. Luckily I remembered the camera..
