Abstract
Abstract A fishing net made from conjugated yarns of a polyamide resin comprising one monofilament to the outer periphery of which are fused two other monofilaments in a longitudinal direction. The two other monofilaments are separate from each other, and the three monofilaments form a conjugated angle θ which is greater than 60 degrees and not greater than 120 degrees.
