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.

Abstract

Fish Aggregating Devices (FADs) are widely used to improve fishing efficiency, and their effectiveness depends largely on attractor design and visual stimuli such as light. This study aimed to evaluate the effectiveness of combining raffia rope attractors and LED lighting on surface FADs in attracting positive phototactic fish (Poecilia reticulata), and to assess their vertical distribution and behavioral responses. A laboratory experiment was conducted using a factorial Completely Randomized Design (position × light presence) with four treatments: bottom without light, bottom with light, surface without light, and surface with light. The primary parameter measured was the number of fish within a 10 cm attraction zone, recorded every 10 minutes for 60 minutes. Data were analyzed using Two-Way ANOVA at a 5% significance level. The results showed that FAD position significantly affected the number of fish approaching the attraction zone (p < 0.05), whereas light presence alone had no significant effect (p > 0.05). However, a significant interaction between position and light was detected (p < 0.05). The highest effectiveness was observed in the surface FAD without light (77%), suggesting that the visual structure of raffia attractors at the surface was sufficient to induce strong aggregation. These findings indicate that the effectiveness of raffia attractors is primarily driven by placement position rather than additional lighting, although their interaction still contributes to fish aggregation behavior. This study provides a practical basis for prioritizing surface FAD placement with raffia attractors over the use of additional lighting in small-scale fisheries.

Abstract

The fourfinger threadfin (Eleutheronema tetradactylum) is an economically important but increasingly threatened species classified as Endangered on the IUCN Red List. This study examined biological aspects of E. tetradactylum in the waters of Mendahara Ilir, East Tanjung Jabung Regency, Jambi. The research focused on the length-weight relationship (LWR), condition factor (K), relative weight (Wr), and size-based fishing eligibility. A total of 340 specimens, consisting 161 males and 179 females, were collected using gill nets. The LWR equations revealed  W = 0.002444L3.3306 (R² = 0.9571) for males and W = 0.005523L3.1116 (R² = 0.9623) for females, indicating positive allometric growth in males and near-isometric growth in females. The t-test confirmed that both b values differed significantly from 3 (p < 0.001). The mean condition factor (K) was 2.83 ± 0.14 for males and 2.91 ± 0.07 for females, while the mean relative weight (Wr) was 101.46 for males and 100.98 for females, indicating good physiological condition and favourable habitat quality. However, analysis of fishing eligibility revealed that only 48.60% of female fish had reached the minimum catchable size (Lc = 40.0 cm), compared to 72.05% of males that exceeded their threshold (Lc = 29.0 cm). The high proportion of undersized female fish raises serious concerns about potential recruitment overfishing. These findings underscore the urgent need to implement for size-selective fishing regulations in Mendahara Ilir waters.

Abstract

Ikan seluang (Rasbora dusonensis) merupakan salah satu spesies ikan air tawar yang umum dijumpai di perairan sungai Sumatera dan memiliki nilai ekologis serta ekonomis bagi masyarakat lokal. Namun, tekanan penangkapan yang terus meningkat memerlukan data ilmiah yang memadai sebagai dasar pengelolaan sumber daya ikan secara berkelanjutan. Penelitian ini bertujuan untuk menganalisis distribusi panjang, pola pertumbuhan, dan tingkat kematangan gonad (TKG) ikan seluang (Rasbora dusonensis) di perairan Sungai Batanghari, khususnya di Desa Muaro Pijoan, Provinsi Jambi. Pengambilan sampel ikan dilakukan pada bulan September menggunakan alat tangkap bubu dan jaring insang berukuran 1,5–2 inci. Setiap ikan yang tertangkap diukur panjang total dan bobot tubuhnya, serta dilakukan pemeriksaan gonad untuk penentuan tingkat kematangan gonad. Distribusi panjang dianalisis menggunakan metode selang kelas, sedangkan pola pertumbuhan dianalisis melalui hubungan panjang–bobot. Penentuan tingkat kematangan gonad dilakukan secara morfologis berdasarkan kriteria literatur. Hasil penelitian menunjukkan bahwa distribusi panjang ikan didominasi oleh ukuran kecil hingga sedang dengan pola pertumbuhan bersifat alometrik. Sebagian besar individu berada pada tingkat kematangan gonad awal, yang mengindikasikan bahwa ikan yang tertangkap belum sepenuhnya memasuki fase reproduktif. Temuan ini memberikan informasi penting sebagai dasar pengelolaan perikanan sungai yang berkelanjutan di wilayah Sungai Batanghari.

Abstract

Lambak fish (Labiobarbus ocellatus) is a freshwater species of ecological and economic importance in the Batanghari River. Basic biological information, particularly the length–weight relationship, is needed to understand growth characteristics and support sustainable fisheries management. This study aimed to analyze the size distribution and length–weight relationship of lambak fish based on fishermen's catches. Sampling was conducted in August 2025 through direct surveys of daily catches using traditional fishing gears. The length–weight relationship was analyzed using the equation W = aLᵇ. The results showed that the samples consisted of 22 females and 33 males. The total length of females ranged from 117–160 mm and males from 100–157 mm, with weight ranges of 15–36 g and 13–40 g, respectively. The regression coefficient (b) values of 2.1483 for females and 2.2459 for males indicated a negative allometric growth pattern. The coefficients of determination (R²) of 0.6904 for females and 0.501 for males suggested relatively strong to moderate length–weight relationships. This growth pattern reflects the species' biological response to environmental conditions

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 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.
