意見 A 22-meter long, 161-kW powered commercial beam trawler was used during the April 1995 survey. At each sampling station, two 2.35-meter headline 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, and then weighed to the nearest gram.
