ຂໍ້ສັງເກດ A 22-meter long, 161-kW powered commercial beam trawler was used during the April 1992 survey. At each sampling station, two 2.35-meter headline Agassiz-type beam trawls were towed from the stern of the vessel for five minutes bottom time. After emptying the catch on deck, the trawls were towed for another five minutes, this time in the reciprocal direction. Fishes were sorted, indentified to the species level, counted, then weighed to the nearest gram.
