castnet = a method of catching fish in shallow waters by throwing a circular net over them; the net opens in the air to a diameter of about 2 metres and sinks rapidly because of weights attached to its margin. The rim of the net has a draw rope that enables it to be closed. Also called throw net or trow net.
