The simplest method of bottom trawling, the mouth of the net is held open by a solid metal beam, attached to two "shoes", which are solid metal plates, welded to the ends of the beam, which slide over and disturb the seabed. This method is mainly used on smaller vessels, fishing for flatfish or prawns, relatively close inshore.

The weight can also be used to cast the line to a further, more appropriate distance at deeper water away from the shoreline. Specialized fishing rods called bottom rods or "donkas" are also commonly used for bottom fishing. In the UK ...
