A. Webber just rang me back from NYS DEC. According to Ms. Webber recreational gill netting of any kind is prohibitted on LI. Commercial Fisherman may use a net in some areas, also highly regulated, only for manhaden and mullet, not tablefare.
Rec. fisherman may use a beach seine (30' x4') or a cast net not exceeding 20' diameter for specific species.
So you know: west of Wantaugh Parkway even commercial guys are prohibitted from using the net.
