Purse seine productivity in Lhok Pawoh fishing port, Sawang, South Aceh

Abstract

The capability of catching from fishing gear can be known from the fishing productivity. The purpose of this study was to calculate the productivity of purse seine vessels in the Fishing Port of Lhok Pawoh, Sawang, South Aceh. This research was conducted from June 10th to July 10th 2019. The method used was a census method by collecting some data such as number of fishing trip (during 2018), species and number of catches, and specification of 15 units of purse seine at Lhok Pawoh fishing port, then the data was analyzed descriptively. The results showed that the material of purse seiner at Lhok Pawoh were made of local wood with a vessel size of 23-60 GT, LOA was 16-24.2 meters, breadth was 4-7.5 meters, depth was 1.3-1.9 meters, and main engine power was 90-360 HP. The purse seine at PPI Lhok Pawoh has a length of between 1,100-1,500 meters and a width of 45-100 meters with the number of fishermen ranges between 18-28 people/unit. The total catches of purse seine during the research was 162,116 kg, dominated by skipjack tuna (67.97%). The highest productivity (production/GT) for large pelagic target was 2,458.8 kg/GT, and the lowest one was 209.3 kg/GT. The highest productivity (production/GT) for small pelagic target was 2,630.7 kg/GT and the lowest one was 418.3 kg/GT. The highest productivity (production/trip) for large pelagic target was 3,046.0 kg/trip, and the lowest one was 187.6 kg/trip. The highest productivity (production/trip) for small pelagic target was 2,067.3 kg/trip and the lowest one was 340.2 kg/trip.

“…Estimated b values from both locations were higher than three as the threshold value, which indicated a positive allometry growth pattern (i.e., the incremental weight gain is more significant than its length). The similarities were likely caused by the indifferences in gear used, whereas Rahmah et al (2021); Rizwan et al (2014); Yusuf et al (2020) all confirmed that fishers from Sibolga and Kutaraja use almost identical purse seine configurations (including its mesh size). Thus, it's generated in a reasonably consistent catch size across the year of observations due to selectivity constraint, as shown in Table 1.…”

“…Purse seine fisheries generally catch pelagic fish [2][3][4][5][6][7][8]. Fish that are the target of the purse seine fishery are pelagic fish that form schools that gather on fishing aids (fish agregating device of iron pontoons).…”

Analysis Of Technical Specifications Of 180 GT Purse Seine Vessel In Fishing Line III Fisheries Management Area (FMA) 572

“…The need for electric power to support the auxiliary system on the 180 GT purse seine boat is 120 kW (150 kVA). From the need for electricity to support fishing operations, two units of electric generators were installed [14].…”
