Abstract

The government of Bengkalis Regency has yet to empower the fishermen in the fishing center of Bantan District according to the fishermen's expectations. Bengkalis Regency through Fisheries Office still have difficulty in developing fishermen empowerment strategies that are in line with fishermen's expectations. The existing empowerment strategies does not take into account the socio-economic aspects of fishermen, so fishermen are not encouraged to adopt advanced fishing technology. The purpose of this research is to identify and study the socio-economic aspects of fishermen to understand why they reluctant to adopt advanced fishing technology. This research was conducted in the fishing centers of Pambang Pesisir and Selat Baru Village. Data were collected through in-depth interviews with representative respondents such as fishers, fisheries extension workers, and officers from Fisheries Office. Descriptive analysis was conducted by taking into account the causal factors that will be used to formulate strategies to empower fishermen in the application of fishing technology by taking into account the socio-economic aspects that influence it. The goal to be achieved is for the fishermen to believe in and be willing to adopt more advanced technology. The socio-economic aspects that most influence the adoption of advanced technology are obedience to local authority and availability of capital. The Bengkalis district government's strategy is to reactivate the savings and loan cooperative while facilitating professional management, and the government is working with the village head and Atok (local leader) to gain the fishermen's trust in the empowerment efforts

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

Abstract

Tuna fishing not only generates significant economic profit, but also has negative environmental impacts due to the intensive use of materials, equipment, and energy. This study aims to identify and measure the input and output components of the tuna fishing process using longline vessels at the Cilacap Oceanic Fisheries Port through a life cycle inventory (LCI) approach. Data collection was carried out through field observations and structured interviews with 30 selected stakeholders, including the analysis of vessel specifications, fishing gear, and supplies. The results of the study show that supplies dominate operational inputs with a total mass of 62,026 kg/year. This indicates a high resource intensity, requiring 29.31 kg of material  input to produce 1 kg of tuna. In addition, this activity produces outputs in the form of significant environmental impacts, including Sulfur Oxide (SOx) emissions of 707.62 kg/year due to diesel fuel combustion and solid waste of 33,550 kg/year, predominantly consisting of single-use plastic packaging from leftover supplies. These findings indicate the need for improvements in logistics components from the upstream side and waste management strategies in the fisheries sector.
