A few features help distinguish the flounder caught recreationally along New Hampshire’s coast that have size regulations: Orientation of the eyes (right- or left-eyed); mouth size; and shape of the lateral line or tail. Recreational saltwater anglers in N.H. most commonly catch winter flounder, followed by yellowtail, summer flounder and American plaice. While not often caught, Atlantic halibut are the largest flounder found in the Gulf of Maine.
Regulations in red are new this year.
