Abstract

This study aims to examine the differences in gill net catch results with the lunar phase in Penampi Village and Kelebuk Village, Bengkalis Regency. Data were collected from January 5 to April 5, 2024, involving 15 fishermen (eight from Penampi Village and seven from Kelebuk Village). Global Positioning System (GPS) technology was used to record the route of the boats, the number of catches (tails), and the total weight (kg) during fishing activities. Statistical analysis using an independent t-test was conducted to evaluate the effect of the lunar phase on catch results. The study found that the lunar phase did not significantly affect the number of catches (fish). However, catch weight was significantly influenced by the dark lunar phase (173.9 kg) and the semi-dark phase (30.5 kg). This study provides important insights into gill net fishing practices in the region. Fishermen are advised to focus on fishing during the dark moon phase, as this period yields the highest catch weight. During the semi-dark phase, fishermen are advised to consider alternative strategies, such as adjusting fishing locations and times to improve catch outcomes. Additionally, weather and sea conditions should be monitored to support the success of fishing activities.

Abstract

Togok is one of the fishing gear that is operated in Kuala Tungkal, Tanjung Jabung Barat Regency, this fishing gear is in the form of a conical net body whose arms are tied to two poles and the success of catching it relies on currents, togok fishing gear is used by Kuala Tungkal fishermen to catch rebon shrimp (Acetes japonicas) but in operation, there are many other types of catch. This study aims to determine the main catch, bycatch, and discards and to determine the size as well as the number of togok catches. This research was conducted on April 5 – July 10, 2021. This research was conducted using experimental fishing methods, namely by conducting direct operations with local fishermen. The results of the study that the percentage of the catch of the main catch by 28%, bycatch 51%, and discard 21%. For the size of the catch of togok species of shrimp (crustacean), there are many sizes that have reached maturity or are suitable for catching while in the catch of fish species there are many sizes that are not yet mature. And for the number of catches in the catch togok main catch amounted to 550800 tail, the catch of the bycatch 79281 fish, and the catch of the discard 10186 fish.

Abstract

Artocarpus stems (Artocarpus sp.) and Carex grass (Carex sp.) have not been applied to fishing gear materials. The fibers produced made into a rope, where this rope is used to absorption and sinking speed test in fresh water and sea water.The absorption of Artocarpus stems rope was 320.30% and 282,60% in fresh water and sea water. Meanwhile for sinking speed have a 5,78 cm/s and 5,08 cm/s for fresh water and sea water. For the Carex grass rope, the absorption in fresh water and sea water was 287,67% and 218,02%. Sinking speed value 2,97 cm/s and 2,67 cm/s for fresh water and sea water. The value of absorption and sinking speed in fresh water is higher than in sea water for both types of rope

Abstract

This research was conducted for five months from May to September 2022 which is located in Sungai Apit District by taking six (6) villages as sampling locations from the eight (8) existing villages. This research was conducted for five months from May to September 2022 which is located in Sungai Apit District by taking six (6) villages as sampling locations from eight (8) existing villages. The research objective was to calculate and assess the adaptive capacity of mangrove ecosystems in Siak District, Siak Regency. Measurement of the adaptive capacity of mangrove ecosystems is carried out by analyzing six parameters, namely Mangrove Dimension Index (IDMg), Dominant Mangrove Species, Mangrove Tree Density, Number of Mangrove Species, Substrate Type, Ecosystem Distance from Settlement. The value of the adaptive capacity of mangrove ecosystems is in the range of 0.0-1.0, with five capacity categories namely "very low, low, medium, high, and very high". The results showed that the number of mangrove species found growing on the coast of Sungai Apit District was 19 species belonging to 10 families and 12 genera, distributed in the "low" category with a mangrove dimension index (IDMg) value of 0.6 (0.4<IDMg <0.8).Dominant species from the Rhizophoraceae family with a density classified as "high". The adaptive capacity of the mangrove ecosystem at the study site is classified as "high" with an adaptive capacity value of 0.67 (0.6 ≤ KPMg ≤ 0.8).

Abstract

Fishing technology has undergone rapid development in response to sustainability challenges; however, a comprehensive global synthesis of its research progress and future directions remains lacking. To address this gap, this study explores global trends and prospects in fishing technology research using an innovative bibliometric approach. A total of 164 Scopus-indexed documents published between 2009 and 2023, authored by 179 researchers across 33 countries, were analyzed. Bibliometric analysis was conducted using the Biblioshiny application in the Bibliometrix R package, complemented by knowledge domain visualization (KDV) to map scientific structures, collaboration networks, and citation patterns. The results indicate an annual publication growth rate of 12.3%, reflecting increasing global interest in fishing technology. China was identified as the most productive country, with the strongest record of international collaboration, while Cooke SJ emerged as the most influential scholar, with a PageRank score of 0.0204 and accounting for 18.25% of global citations. Keyword mapping revealed research hotspots centered on sustainable development, selective fishing gear, and the integration of digital technologies, including artificial intelligence and electronic monitoring. This study concludes that bibliometric synthesis not only provides a strategic overview of global knowledge gaps and thematic evolution but also highlights the critical role of interdisciplinary collaboration and technological innovation in shaping the future of sustainable fisheries management. Keywords:   Bibliometrics analysis, fisheries, fishing technology
