• A series of frictional experiments were carried out the wear and tear of various fishing nets to friction, and these wear resistances of different nets were compared to each other, and an analysis made. This report is concerned with the results of trawler knot nets made of polyester and nylon, and knotless net of polyester. The following results were obtained. 1. It is concidered that the wear resistance of nets are related to the roughness of the net surface; and the more the coefficient of friction of the net, the less the wear resistance. 2. The wear resistance of trawler knot net rubbed to the lengthwise direction of meshes is exceedingly less than that of the same net rubbed to the sidelong direction. Accordingly, fishermen should take concideration of this fact when designing their fishing gear.
