Abstract

Pengoperasian pukat cincin di Selat Sunda menggunakan alat bantu lampu jenis metal halide untuk menarik ikan target agar berkumpul di catchable area. Adanya asumsi bahwa semakin terang lampu yang digunakan dapat meningkatkan hasil tangkap mendorong nelayan menggunakan lampu dalam jumlah banyak dan daya yang besar. Padahal setiap jenis ikan memiliki preferensi dan kemampuan adaptasi yang terbatas terhadap cahaya yang diterimanya. Penelitian ini bertujuan untuk menentukan tingkat adaptasi mata ikan tongkol (Euthynnus affinis) yang ditangkap oleh pukat cincin di Selat Sunda berdasarkan jumlah lampu yang berbeda. Pengumpulan data dilakukan pada bulan Mei hingga Juli 2021 dengan mengikuti operasi penangkapan ikan yang dilakukan oleh kapal pukat cincin dengan dua kapal lampu yang berbeda (kapal yang dilengkapi 8 lampu dan kapal yang dilengkapi dengan 6 lampu). Intensitas cahaya lampu pada medium air diukur menggunakan ILT 5000 research radiometer. Pengambilan sampel mata ikan tongkol dilakukan masing-masing sebanyak 3 ekor pada setiap trip yang selanjutnya diproses dengan metode histologi. Hasil penelitian menunjukkan intensitas cahaya pada kapal yang menggunakan 8 lampu lebih tinggi dibandingkan dengan kapal yang menggunakan 6 lampu. Namun demikian, pada kedalaman > 10 m, intensitas cahaya yang dihasilkan oleh kedua kapal tersebut relatif sama. Nilai indeks kon ikan tongkol hasil tangkapan kapal dengan 6 lampu rata-rata 90,76% sedangkan pada kapal dengan 8 lampu sebesar 91,50%. The purse seines fishing operation in the Sunda Strait uses metal halide lamps to attract target fish to congregate in catchable areas. There is an assumption that brighter lights can increase the catch, encouraging fishermen to use lights in large quantities and with high power. Even though each type of fish has preferences and limited adaptability to the light it receives. This study aims to determine the level of adaptation of the tuna (Euthynnus affinis) caught by purse seines based on the number of different lights. Data collection was conducted from May to July 2021 through experimental fishing on a purse seiner fishing vessel with two different numbers of lamps, including 6 lamps and 8 lamps for each boat respectively. The light intensity in the seawater was measured using an ILT 5000 research radiometer. A sampling of the eye of the tuna was carried out by 3 individuals on each trip which were then processed using histological methods. The results showed the light intensity on the boat using 8 lights was higher compared to boat using 6 lights. However, at depths > 10 m, the light intensity produced by both was similar. The average cone value of Mackarel tuna captured on the boat with 6 lights is 90.76%, while for a boat with 8 lights, it is 91.50%.

Abstract

The purpose of this research are to determine the average distribution of SST, chlorophyll-a, and see surface currents, and analyze the relationship between them with pelagic fish catches as an analysis material for determining pelagic fishing area in Banten’s Southern Sea. Data collected includes SST and chlorophyll-a using Aqua MODIS images data and and see surface currents data from Copernicus Marine Data for 6 years. The data was processed to produce the value of each parameter and then analyzed the parameters with the catches and determine the potential pelagic fishing area. The results showed that the SST throughout 2016 had a relatively high value allegedly due to the negative Indian Ocean Dipole (IOD). During the eastern until the end of second transitional season in 2019 there was a positive IOD which caused SST to decrease and chlorophyll-a to be larger than in other fishing seasons. See surface currents in the western season tend to be larger than in other fishing seasons. SST and chlorophyll-a have a stronger relationship with catches than see surface currents. The potential fishing area are around Tanjung Mantiyung, Muara Binuangeun, dan Tanjung Panto.

Abstract

Binuangeun Fish Landing Base (FLB) is the largest tuna-producing port in Banten Province. Tuna production in 2019 amounted to 26% of the total catch. The purpose of this study was to identify distribution activities and calculate marketing efficiency. The research was conducted in February-August 2023 at Binuangeun FLB of Banten Province. The method used is the survey method. The sampling technique was carried out by purposive sampling. Margin analysis and marketing efficiency (Fisherman's share) are used to determine differences in fish prices, as well as how efficient the marketing process is. The results obtained are four marketing channels, namely the first channel (fisherman, fish auction, fish brokers, consumers), the second channel (fisherman, fish auction, collectors, processing, companies, consumers), the third channel (fisherman, fish auction, collectors, traders outside the region, consumers), the fourth channel (fisherman, fish auction, fish brokers, retailers, consumers). The highest margin is found in marketing channel II, which is IDR 10,000 (50%). The lowest margin is found on the fourth channel with a value of IDR 3,000 (12%). Tuna marketing at PPI Binuangeun is quite efficient. The highest efficiency value is found in marketing channel one. The lowest efficiency value is found in the second channel.

Abstract

The coastal area of Panimbang, severely impacted by the 2018 Sunda Strait tsunami, has been the focus of rehabilitation due to its vulnerability from the absence of natural barriers like mangroves, which are crucial in mitigating tsunami effects. Through the Mangrove Blue Carbon program, 10,000 mangrove seedlings were planted in Panimbang Jaya Village to restore the coastal ecosystem. This study evaluates the relationship between sediment characteristics and mangrove growth. Measurements included water quality (temperature, pH, salinity), mangrove growth indicators (height, stem diameter, branch and leaf counts), and sediment characteristics (texture, organic carbon, nitrogen, and phosphorus). Results showed water quality supported mangrove growth. Temperature increased from 30.96°C (2023) to 32.6°C (2024) due to El Niño but remained within tolerance limits. pH rose from 7.54 to 8.02 (optimal 6–9), and salinity increased from 16.66‰ to 19.34‰ (tolerance 10–30‰). Sediment texture was predominantly sandy (>90%) with low fertility, indicated by organic carbon (1.5–3.2%), nitrogen (0.2–0.6%), and phosphorus (0.01–0.04%). Mangrove growth improved significantly, with height increasing from 120–150 cm to 160–210 cm, stem diameter from 2.0–3.2 cm to 3.5–4.8 cm, branch count from 5–8 to 8–12, and leaf count from 20–35 to 35–50. Mangrove growth correlated with clay texture and carbon-rich sediment despite low fertility, while optimal water quality still supported their. This emphasizes the need for ongoing monitoring and sustainable rehabilitation efforts to ensure the success of ecosystem restoration.

Abstract

Increasing of fishing pressure poses a serious threat to the sustainability of blue swimminng crab resources. Trap design modifications are needed to improve size selectivity and to release under size crabs. This study aimed to determine the type of wall modification of collapsible trap that is effective in excluding under size blue swimming crab. Laboratory observations were conducted using four escape vents treatments and three different mesh sizes. The escape gap used are rectangular, square, circular and oval respectively. Moreover, the mesh sizes used are 2.0 inches, 2.5 inches and 3.0 inches. Descriptive analysis and scoring were used to determine the most effective type of wall trap modification to be used in the blue swimming crab fishing. The results showed that the rectangular escape gap has better effectiveness than other shapes with the percentage of crabs that pass through at 86.7%. The wall modification using a 3.0-inch mesh size had better performance than the other modification types with a total score of 19. Collapsible trap with a 3.0-inch mesh wall was able to escape 86.7% of the crabs with an escape time of only 11.2 seconds and an average escaped crab carapace width of 78 mm. Keywords: Collapsible trap, escape gap, environmentaly-frendly fisheries, mesh size of trap wall

Abstract

Blue swimming crab is one of the capture fisheries sector leading commodities in Banten Bay which is caught using gill nets and collapsible traps. The risk of lost fishing gears during operation is very high, both due to the bad weather and interactions with other fishing gear. The Abandoned, Lost or Discarded Fishing Gear (ALDFG) contributes significantly to the abundance of marine plactics in the world which has a negative impact on the sustainability of fish resources, water quality and endangers the safety of navigation. Nevertheless, there have been no mitigation activities and efforts to reduce ALDFG in the Banten Bay. This study aims to identify the global causes of lost fishing gear derived from blue swimming crab fisheries in Banten Bay. Data were collected around the Archipelagic Fishing Port (PPN) of Karangantu in May-June 2022. In-depth interviews were conducted with 28 respondents who were selected purposively and the results were analyzed descriptively. The results showed that generally, the causes of lost gear were conflicts with other fishing gear which constitute 64%, whilst human errors during fishing operations and bad weather contributed 19% and 17%, respectively. Keywords: ALDFG, conflict, blue swimming crab, lost gear.
