Modifying otter boards to reduce bottom contact: Effects on catches and efficiencies of triple-rigged penaeid trawls

Two otter-board modifications designed to minimise bottom contact (and therefore habitat impacts) were compared against conventional otter boards for their relative effects on the engineering and catching efficiencies of triple-rigged penaeid trawls. The first modification involved restricting the angle of attack (AOA) of a flat-rectangular otter board t
