Abstract

Bitung City is one of the centers for fisheries production, with the main commodity being capture fisheries, specifically small pelagic fish (mackerel scad (decapterus), mackerel fish (Rastrelliger), tuna (Euthynnus affinis) , and anchovy (Stolephorus indicus)). The purpose of this research is to describe the construction of a floating net cage to support the successful capture of small pelagic fish. The study was conducted from October to December 2024. The data collection methods used were observation and direct interviews with fishermen, and the data were analyzed using qualitative descriptive analysis. The results of the study show that the construction of the lift net includes: a wooden frame measuring 9.5 x 8.5 meters, wooden and net enclosures measuring 3x3 meters, 24 LED lights, a polyethylene net (Cang) measuring 9.5x8.5 meters, a guard house made of wood measuring 2x2 meters, 15 river stones as weights, 4 sand-filled anchors in bags, 12 brass rings, 1 wooden reel, and 24 styrofoam buoy floats.

Abstract

The waters of Bitung, located in North Sulawesi Province, have long been known for their rich underwater biodiversity, specifically unique and exotic creatures. They are a potential demersal fishing ground for coastal fishermen in Bitung City. However, information on demersal fishing grounds is limited, so it is necessary to conduct research and map demersal fishing grounds in Bitung waters. This study aims to obtain data on the geographical position of demersal fishing areas in Bitung waters to be mapped into a map of demersal fishing areas in Bitung waters and determine the types of catches from bottom fishing rods. Data was collected directly by following demersal fishing operations on the training ship FV. Coelacanth. The data were analyzed using survey methods and direct observation, which is an effort to collect information directly from a part of the population that is considered a specified population and has the nature of authentication or checking of existing theories. The study's results obtained geographical data on demersal fishing areas in Bitung waters at (1) 10°23.447' N, 125°06.934' E (Suar Batu Kapal area),, (2) 10°23.483' N, 125°09.567' E (Karang Tanjung Merah area) (3) 10°23.283' N, 125°10.852' E (Batu Angus Area), (4) 10°30.393' N, 125°15.392' E (Menara Lampu Hijau Area), and (5) 10°32.706' N, 125°18.105' E (Dua Pulau area). The primary catches of bottom fishing consist of fish species: grouper, snapper, trevally fish, Gora fish, emperor fish and parrot fish.

Abstract

The majority of fishermen in Batu Putih Atas Subdistrict, Bitung City, use lift nets (bagan apung) as their primary fishing gear. The uncertainty of fishing operations due to seasonal changes highlights the need for a thorough economic feasibility analysis. This study aims to evaluate the economic viability of lift net fishing activities. Data were collected through surveys and interviews, and analysed using a descriptive quantitative approach based on financial data. The results show that lift net fishing in Batu Putih Atas is financially profitable. The annual total revenue reached IDR 432,000,000, with a net profit of IDR 334,550,000. The total annual catch amounted to 1,440 buckets (equivalent to 72 metric tons), with anchovies comprising 65% of the catch. Based on the analysis of the Revenue-Cost Ratio (R/C ratio), Break-Even Price, Break-Even Production, and Payback Period, lift net fishing is considered economically feasible and viable for continued operation..

Abstract

One source of marine pollution can be caused by the operational activities of fishing vessels. This research aims to identify the type and amount of waste originating from fishing vessels. Data collection was conducted at Bitung Ocean Fishing Port during November-December 2023 by purposive sampling. The waste that has been collected, sorted and weighed. Data were analysed using descriptive quantitative. The waste generated by fishing vessels consists of two types, namely organic and inorganic waste. Organic waste consists of food waste and kitchen waste, while inorganic waste consists of 70% plastic, 12% processed wood, 10% glass, 6% clothing or cloth, and 1% metal and rubber. Organic waste is disposed of directly into the sea, while inorganic waste is collected in storage containers for later disposal on land. There is a need for more action in fishery vessel waste management, such as training in recycling that can generate economic benefits, in an effort to reduce waste from fishing vessels.

Abstract

Kelurahan Girian Bawah Kota Bitung didominasi oleh nelayan perikanan tangkap dan tidak menutup kemungkinan aktifitas penangkapannya dapat meningkat sehingga menyebabkan stok sumberdaya ikan mengalami penurunan. Pemanfaatan dan pengelolaan sumberdaya ikan harus dilakukan secara bertanggung jawab agar tetap lestari dan berkelanjutan mengingat sifatnya yang open access dan common properties. Kegiatan pengabdian masyarakat dapat dijadikan wadah untuk mentransfer ilmu pengetahuan dan keterampilan dalam bentuk program pendidikan masyarakat. Tujuan dari kegiatan ini adalah mengedukasi kelompok nelayan Kelurahan Girian Bawah, Kota Bitung tentang penangkapan ikan yang bertanggung jawab dan ramah lingkungan. Metode pelaksanaan kegiatan meliputi tahap survei, tahap persiapan, tahap pelaksanaan melalui penyuluhan dan sosialisasi serta tahap evaluasi. Hasil yang diperoleh bahwa kegiatan tersebut dapat dikatakan berjalan dengan baik yang dilihat dari peserta antusias dan aktif berdiskusi secara terarah dengan tim dosen

Abstract

Fisheries activities at the Bitung Ocean Fishing Port (PPS) have the potential to cause pollution, particularly due to waste generated by fishing vessels. Waste generated on board is categorized into two types: organic and inorganic waste. Information on waste management aboard fishing vessels based at PPS Bitung is minimal and very limited. The aims is to study waste management aboard these vessels and analyze waste management strategies. The research was conducted from August to November 2024 at PPS Bitung. Data were collected using survey methods and interviews with respondents selected through purposive sampling. Data were collected using survey methods and interviews with respondents selected by purposive sampling. Data analysis used descriptive methods with a qualitative approach, and waste management strategies were analysed using SWOT analysis. The results showed that the categories of waste generated by fishing vessels include wet waste (food), which is directly dumped into the sea, and dry waste such as plastic, bottles, cloth, glass, and metal, which are collected first. Dry waste management is carried out in two ways, namely without sorting and with sorting. The waste management strategy on board fishing vessels in PPS Bitung is designed to increase environmental awareness and waste management efficiency through an integrated approach. The combination of education, regulation and partnership provides a comprehensive solution to minimize the environmental impact of waste and increase the active participation of crew members in waste management. Consistent implementation of this strategy can serve as a model for sustainable waste management in the fisheries sector.

Abstract

Albacore (Thunnus alalunga) is one of the most economically important tuna species in tropical waters, including Indonesia. High levels of tuna exploitation can be minimized through fisheries management that requires stock and biological data.  The purpose of this study was to analyze the size distribution, percentage of fish suitable for capture, and the relationship between length and weight of Albakora (Thunnus alalunga) landed at Benoa Port. The study was conducted from January to April 2024 by taking 200 samples of Albakora (Thunnus alalunga) landed at Benoa Port. The analysis methods used were length distribution, length and weight relationships, and catchable size of Albacore (Thunnus alalunga). The analysis results showed that the frequency distribution of Albacore (Thunnus alalunga) length was highest in the range of 100 cm – 106 cm, with 66 fish. A total of 85% of Albacore (Thunnus alalunga) were in the catchable category, while 15% were in the non-catchable category. Albacore growth is negatively allometric (b<3), meaning that fish length grows faster than weight. The condition of Albacore fisheries in the Indian Ocean is classified as overfishing, thus requiring proper management...
