This study aims to determine the construction of trammel net based in East Coast Pangandaran, West Java, Indonesia. Data collection was carried out from September 2019 to April 2020 using trammel net fishing gear located on the East Coast, Pangandaran. The method used is quantitative descriptive by analyzing the construction of the fishing gear, fishing method, the composition of the type of catch and the size of the main catch. The results showed that the trammel net fishing gear used by fishermen in Pangandaran had a construction consisting of 4 mm buoy rope with polyethylene (PE) material, 5 mm upper rope with polyethylene (PE) material, 16-inch picture strap mm with polyethylene (PE) material, outer net body with polyethylene (PE) monofilament material and mesh size of 1.75 inches and inner net body with polyamide (PA) monofilament material and mesh size of 1.75 inches, Y-30 float and lead ballast. The Hanging Ratio (E) of the outer net is 0.54 and the inner net is 0.47. The method of operating the trammel net in Pangandaran is carried out by being pulled or dragged at the bottom of the water by the ship so that it forms a circular net or by active fishing system method. The main catches consist of Penaeus merguiensis and Metapenaeus ensis as much as 70% and 30% bycatch, and the composition of mature size catch on main catches is 78.66%.
