Fishing Net

Abstract

A typical fishing net, with diamond-shape openings, can be manufactured according to different techniques by different machines. Depending on the fish-size, the opening size and the thickness of the mesh-bars are designed to hold the catch. Traditionally nets were hand-knotted and later machine knotted which are both slow processes with many disadvantages. The mesh-bars are made of one yarn which must be twisted to prevent filamentation, the structure and particularly the knots are not strong, the net is very vulnerable on account of the protruding knots and, in some cases, the knots even loosen when immersed in the water.
