Abstract

A sled is hauled over the seabed and accommodates an adjustable blade cutting into the latter, a fish basket, and a nozzle with an oblong opening which delivers water under pressure. The pressure is generated by an auger-type pump (11, 12,14) before the nozzle (10), mounted on the sled (2) and with a drive unit, typically in the form of a direct-coupled electric motor. The nozzle and pump assembly (12) can hinge on the sled so as to vary the jet angle. The design allows fishing in relatively deep water.
