Abstract

The Batang Asai River in Sarolangun Regency, Jambi, is one of the major rivers with a length of approximately 104 km. Currently, its water quality is declining due to anthropogenic activities such as land clearing, settlements, and mining. This condition threatens the sustainability of fish populations, particularly those from the Cyprinidae family, which are important food fish and sensitive to environmental degradation. However, scientific information regarding the bioecology and spatial distribution of Cyprinidae in this area remains very limited. Therefore, this study is necessary to provide baseline data to support adaptive conservation strategies and fisheries management. The objectives of this research are to identify Cyprinidae species, analyze bioecological aspects (morphometrics, diversity, reproduction, and habitat characteristics), map spatial distribution based on GIS, and determine conservation status according to the IUCN Red List. The study was conducted in August 2025 at three observation stations. The methods used include field surveys, bioecological analysis, and GIS-based spatial mapping. The results showed that 19 species of Cyprinidae were identified with a total of 482 individuals. The fish diversity index value of 2.07 indicates a moderate diversity category, with an evenness value of 0.70 and a dominance value of 0.17. The sex ratio of males to females was 1.9:1, dominated by fish at gonadal maturity stage (GMS) I with 263 individuals. In general, the water quality of the Batang Asai River still supports fish life, and no species were classified as threatened according to the IUCN Red List.

Abstract

apiat (Barbonymus schwanefeldii) is one of the economically important freshwater fish found in the Muaro Pijoan River, Jambi. Intensive fishing pressure and water quality degradation due to anthropogenic activities pose threats to the sustainability of this fish population. This study aims to examine the size distribution and growth patterns of kapiat in the Muaro Pijoan River as a scientific basis for development of freshwater aquaculture. Sampling was conducted in October 2025 using traps and gillnets. A total of 83 kapiat were collected, consisting of 51 males and 32 females. Male fish had a total length range of 110–160 mm with a weight range of 20–55 g, while female fish had a total length range of 120–166 mm with a weight range of 21–71 g. The size distribution of male fish was dominated by the 134–141 mm size class (25 individuals), while female fish were dominated by the 156–164 mm size class (13 individuals). Length-weight relationship analysis showed that male fish exhibited a negative allometric growth pattern (b = 2.6399; R² = 0.7313), indicating that length growth was faster than weight gain. In contrast, female fish exhibited a positive allometric growth pattern (b = 3.4445; R² = 0.8998), indicating that weight gain was faster than length growth due to the gonadal maturation process. The relatively smaller size distribution compared to other populations suggests environmental influence on growth performance. These results provide baseline information for domestication strategies, broodstock selection, and feeding management in freshwater aquaculture systems

Abstract

The catch is influenced by the catch rate of fishing gear. This study aims to analyze the catch composition, catch rate, frequency of fish emergence, and factors affecting the catch of iron traps in Lake Kerinci. The study was conducted from August–October 2025 with 10 fishermen on 30 fishing trips. The total catch reached 467 fish weighing 90.743 kg, dominated by tilapia at 77.74%, followed by medic fish, freshwater lobster, and climbing perch. Tilapia had the highest occurrence frequency (100%), indicating high abundance in the lake waters. The average catch rate was 30.25 kg/trip with variations between fishermen due to differences in location and water conditions. Regression analysis showed that the operating duration, number, and dimensions of the traps did not significantly affect the catch (R² = 0.10). In general, iron traps are classified as effective, selective, and environmentally friendly, thus having the potential to support sustainable capture fisheries in Lake Kerinci.

Abstract

Small-scale fisheries in coastal areas utilize various fishing gears, including bottom gillnet, which can catch fish species with different trophic levels. Fishing activities may influence the trophic structure of fish communities and the vulnerability of species to exploitation. This study aimed to analyze the trophic structure, vulnerability level, conservation status based on the IUCN Red List, and Mean Trophic Level (MTL) of fish species caught using bottom gillnet in the coastal waters of Lambur Luar Village, Tanjung Jabung Timur Regency. The study used a survey method with data collected through direct observation of fishermen's catches. Data analysis included catch species composition, trophic level values ​​obtained from the FishBase database, vulnerability analysis of each species, identification of IUCN conservation status, and calculation of Mean Trophic Level (MTL) based on the proportion of catch composition. The results showed that the catches consisted of 20 species, with trophic groups dominated by mesopredators (50%) and top predators (25%), while omnivores and herbivores were found in smaller proportions. Vulnerability analysis indicated that most species were categorized as having low to moderate vulnerability, although several species showed high vulnerability to fishing pressure. Based on the IUCN Red List, most species were classified as Least Concern (LC). The calculated Mean Trophic Level (MTL) was 3.2, indicating that the catches were dominated by mid-level carnivorous fish species.

Hal ini bertujuan untuk mengetahui struktur komunitas mangrovenya berdasarkan analisis cluster dan nMDS. Vegetasi mangrove dikumpulkan dengan menarik transek kuadran yang tegak lurus garis pantai, kemudian data vegetasi mangrove dievaluasi menggunakan cluster dan nMDS. Keanekaragaman mangrove Desa Bagan Serdang teridentifikasi sebanyak 5 spesies dengan 4 famili, dimana penyebaran mangrovnya tergolong sesekali ditemukan (rata-rata frekuensi relatifnya 20,00%). Zona paling depan didominasi oleh Avicennia lanata, zona tengah didominasi oleh Rhizophora apiculata dan zona belakang didominansi oleh Rhizophora mucronata. Kerapatan mangrovenya berkisar antara 22,22 – 1222,22 ind/ha dan INP berkisar antara 9,64 – 231,78% dengan kerapatan vegetasi zona depan maupun tengah membentuk satu kelompok yang mengindikasikan kondisi kerapatannya hampir sama. Selanjutnya untuk INP, vegetasi zona depan dan tengah membentuk satu kelompok dengan spesies yang berperan penting adalah A. lanata serta R. apiculata, sedangkan di zona belakang, spesies yang berperan pentingnya adalah R. mucronata, E. agallocha dan X. granatum. Selain itu, basal area vegetasi mangrove Desa Bagan Serdang berkisar antara 278,22 – 654,35 m2/ha dengan basal area vegetasi zona depan maupun belakang memiliki tingkat kedewasaan yang hampir sama, sehingga membentuk satu kelompok. Kajian ini mengungkapkan adanya komposisi spesies mangrove campuran dengan perkembangan kedewasaan mangrovenya berbeda-beda. Data yang diinfokan dalam kajian ini akan menjadi baseline pengelolaan mangrove di Desa Bagan Serdang dan upaya konservasi di Provinsi Sumatera Utara maupun Indonesia.  Multivariate analyses such as clusters and nMDS are frequently used to facilitate in the interpretation of environmental data. In contrast, the community structure of plant vegetation is immensely useful in describing the ecology of an ecosystem. In September 2021, studies on the mangrove community structure of Bagan Serdang Village were conducted using cluster analysis and nMDS. It proposes to use cluster analysis and nMDS to determine the structure of the mangrove community. Mangrove vegetation was collected by pulling quadrant transects perpendicular to the shoreline, and the data was analyzed using clusters and nMDS. The diversity of mangroves in Bagan Serdang Village was identified as 5 species with 4 families, with mangrove distribution classified as occasional (average relative frequency of 20,00%). Avicennia lanata dominates the front zone, Rhizophora apiculata dominates the middle zone, and R. mucronata dominates the back zone. The mangrove density ranges from 22,22 to 1222,22 ind/ha, and the INP ranges from 9,64 to 231,78%, with the vegetation density in the front and middle zones forming one group that shows nearly the same density conditions. Furthermore, for the INP, the front and middle zone vegetation formed a group with species that played an important role which were A. lanata and R. apiculata, while species that played an important role in the rear zone were R. mucronata, E. agallocha, and X. granatum. Furthermore, the basal area of the mangrove vegetation in Bagan Serdang Village ranges from 278,22 to 654,35 m2/ha, with the basal area of the vegetation zones front and back having nearly the same maturity level, forming a single group. This study reveals the presence of a mixed mangrove species composition with different mangrove maturity developments. The data presented in this study will be the baseline for mangrove management in Bagan Serdang Village and conservation efforts in North Sumatra Province and Indonesia.
