    • 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). In one aspect, an improved netting (15) has at least one of the twines (11, 13) selected to have an unequal cross-sectional aspect ratio. In another aspect, an improved netting (15) uses different materials for the netting's basic twine (13) and shuttle twine (11). Also, a specifically selected bonding material is applied to the twines (11, 13) made from differing materials, the specifically selected bonding material exhibiting a greater affinity for the material of one of the twines (11, 13) than for the other (13, 11).

    • 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.

    • A trawl door (20, 60) or a paravane (120, 140) having at least one main deflector (22, 22U, 22L) includes a permeable structure disposed adjacent to and separated from an outer surface (34) of the main deflector (22, 22U, 22L). The permeable structure extends from near a trailing edge (26, 26U, 26L) of the main deflector (22, 22U, 22L) over and separated from the outer surface (34) toward the main deflector's leading edge (24, 24U, 24L). In one embodiment of the permeable structure, a plurality of apertures (54, 56) pierce a perforated slat (52, 52U, 52L) thereby establishing a porous surface adjacent to the outer surface (34) of the main deflector (22, 22U, 22L). Adding the permeable structure perforated slat (52, 52U, 52L) to a trawl door (20, 60) increases the trawl door's stability when the trawl door is towed through water at a high angle of attack, and also reduces the trawl door's drag when operating at a high angle of attack.
