ข้อสังเกต | Monthly sampling was done from December 1978 to December 1979, using a conventional beam trawl. The trawl was towed for 5 minutes at about 80 to 100 meters per minute, covering an area of approximately 1000-1200 square meters. Seven monthly hauls were taken at each station, with each haul completed within 45 minutes. |
