摘要： Netting (15) includes mesh bars (26) made from twines (11,13) which possess physical properties that vary, change or alternate along a series of collinear mesh bars (26). The non-homogeneous media obtained by arranging in this way mesh bars (26) having varying physical properties may be configured to dampen or attenuate vibrations in the netting (15) such as harmonic oscillations (resonance). Furthermore, twines (11, 13) that attenuate vibrations may be chosen that also reduce the amount of material required to make netting (15) which has strength similar to or greater than conventional machine-made netting (15). Due to reduced vibration, the improved netting (15) lasts longer than conventional machine-made netting (15), and reduces the possibility of injury to fish which escape through a trawl's mesh cell openings.
