| Definition | The semi-balloon trawl (OTSB14), complete with "V" doors was originally obtained from the Marinovich Trawl Company (Biloxi, Mississippi, USA). It was constructed of 4.4 cm stretch mesh body and 3.7 cm mesh intermediate and cod end, with a 1.3 cm inner liner in the cod end. Buoyancy on the headline was provided by one centrally placed glass sphere having a positive buoyancy of 5 kg. Twenty three 13 x 15 cm plastic mud rollers were spaced evenly along the footrope (17 m), with three loops of 6 mm chain in between each set. A pair of sweep lines on each side separated the "V" doors by 7 m from the wing ends of the net. The height of the wing ends between headline and footrope was 1.5 m. The doors, each measuring 1.5 x 1 m and weighing 180 kg; were connected by bridles 50 m in length, through a swivel to the single trawl warp. | |
