Abstract

This research aims to determine the diversity of purse seine vessels based on gross tonnage measurements which was carried out from April 2023 to July 2023. This study collected sampling data on purse seine vessels in the Pekalongan PPN, both when the vessels were berthed, and collective data sourced from the authorities Archipelago Fishing Port (PPN) Pekalongan. In this formulation, it begins with identifying the dimensions of the ship, measuring the volume of the fish hold and interviewing a number of crew members who work on the ship. The aim of this research is to identify the main dimensions of ships and describe the operation of purse seine ships. with an average ship size of over 100 gross tonnages to 200 gross tonnages with a crew of 35 to 40 people.

Abstract

The tuna fishing industry significantly contributes to greenhouse gas (GHG) emissions primarily through fuel oil usage. This study investigates the environmental impact of tuna transportation, focusing on emissions from fishing vessels and vehicles. Carbon footprint calculations for fishing vessels utilize the IPCC, 2006 formula as referenced in KLH, 2012. Smaller purse seiners (10-20 GT) emit 2.88 kg CO2per trip per kilogram of tuna, while those (20-30 GT) in PPS Kutaraja emit 3.58 kg CO2. Larger purse seiners exhibit higher emission rates: 7.3 kg CO2 (20-30 GT), 9.9 kg CO2 (30-40 GT), 8.6 kg CO2 (40-50 GT), and 8.4 kg CO2 (50-60 GT) per trip per kilogram of tuna. Vehicle emissions for tuna transport vary, with the Honda Blade FI 125 emitting 0.00625 kg CO2, Supra X 125 emitting 0.00450 kg CO2, Viar Tiga Roda emitting 0.00458 kg CO2, Revo Fit emitting 0.0007 kg CO2, Jupiter emitting 0.00063 kg CO2, and Vega ZR Yamaha emitting 0.0006 kg CO2 per kilogram of tuna.Keywords:Carbon FootprintEmissionFsihing VesselsGreen TransportationsSupply ChainFishing Activties

Abstract

The catch results show that wire traps are an effective and selective fishing gear for Lutjanus johnii, with a total catch of 244.1 kg. The bycatch, consisting of 10 species, amounted to 208.1 kg, also caught using wire traps in the waters of Rigaih. This study aimed to identify the composition of the bycatch, the ratio between the target catches and the bycatch, and the size range of the dominant bycatch species caught during L. johnii fishing operations in Rigaih waters. The research was conducted in the waters of Rigaih during NovemberDecember 2024 using wire traps (dimensions: length x width x height = 120 x 100 x 75 cm). The results showed that the primary catch using wire traps was dominated by L. johnii, with a total of 135 individuals (48.7%) weighing 244.1 kg. The bycatch amounted to 208.1 kg (46.1%). The bycatch species included Caranx sexfasciatus with 42 individuals (15.2%) weighing 18.4 kg (4.1%), Lutjanus gibbus with 24 individuals (8.7%) weighing 31.9 kg (8.7%), and Epinephelus malabaricus with 24 individuals (8.7%) weighing 114.5 kg (25.3%). The dominant bycatch size classes caught in the wire traps included L. campechanus with a total length range of 1820 cm, L. campechanus with a total length range of 3045 cm, and Epinephelus malabaricus with a total length range of 4075 cm. The proportion of the target catch to bycatch by weight was 53.9% to 46.1%. This means that for every 1 kg of L. johnii caught, approximately 0.85 kg of bycatch was also captured.KeywordsLutjanus johniiwire trapAceh Jayasex ratiofish composition
