A kind of fish-net used especially in Narragansett
Bay, consisting of an oblong inclosure
of netting on three sides and at the bottom,
anchored securely by the side of the channel.
Into this the fish enter, and, the bottom of the net
being lifted to the surface at the open end, they are
penned in and driven into a lateral inclosure, where they
are kept until needed.
