Dictionary of Ichthyology
square net = a net used to catch gaspereau (Alosa pseudoharengus, Clupeidae) in Maritime Canada rivers as they migrate to spawn. A fence is built about one-third across a river to create suitable water conditions. A large square net is laid on the river bed and is attached to a cantilevered pole. When a shoal of fish passes over the net, the observing fisherman puts his weight on the far end of the pole, lifting the net out of the water, the pole end being secured by a hook. Fish are removed with a dip-net and packed in barrels of salt.
