Evaluation and risk assessment of introduced fish species in the ornamental trade and aquaculture epicentre in North Sumatra, Indonesia Agung Setia Batubara, Anastasya Sorta Panggabean, Rahmatsyah Rahmatsyah, Rita Juliani, Syarifuddin Syarifuddin, Firman M. Nur, Ilham Zulfahmi Acta Biologica Slovenica, 2026 While introduced fish initially had a positive impact on the socio-economic aspects of society, they have recently threatened the biodiversity of native fish in Indonesia. Preventive efforts are needed by inventorying introduced fish traded in Medan Regency, as the origin of the entry of alien fish in North Sumatra, Indonesia. This research used a survey method conducted at 30 ornamental fish markets in the Medan Regency area from March to May 2024. The authors classified introduced fish based on conservation status, natural distribution zone, year of introduction, and invasive threats based on various databases and journals. Fish Invasiveness Screening Test (FIST) analysis was also carried out to assess the risk level of the introduced fish. The results of the analysis show that there are 55 introduced fish species traded in Medan Regency, which are classified into 46 genera, 29 families, and 14 orders. The orders Cichliformes and Cypriniformes had the highest numbers of species, followed by Characiformes, Siluriformes, Osteoglossiformes, Anabantiformes, Cyprinodontiformes, and others. There are 13 species of introduced fish that should be prohibited from circulation because they threaten aquatic ecology, including Amphilophus citrinellus, A. labiatus, Cichla ocellaris, C. piquiti, Lepisosteus oculatus, L. osseus, Lates niloticus, Melanochromis auratus, Pterygoplichthys multiradiatus, P. pardalis, Pygocentrus nattereri, Semaprochilodus insignis, and Tetraodon duboisi. The results of the FIST analysis show that 21 species of fish represent a high risk of threat to aquatic ecosystems, followed by 13 species at moderate risk, and 21 species at low risk.
Morphological variation of the endemic sisorid fish, Glyptothorax platypogon (Teleostei: Sisoridae) from Java, Indonesia: conventional and truss-based morphometrics Tonisman Harefa, Haryono Haryono, Rudhy Gustiano, Firman M. Nur, Gema Wahyudewantoro, Rusdianto Rusdianto, Daniel F. Mokodongan Egyptian Journal of Aquatic Research, 2026 Landmark-based morphometrics approaches including conventional morphometric and truss-based measurements, are widely used to assess fish population status and understand adaptation to environmental diversity. This study aimed to investigate the morphometric variations of Glyptothorax platypogon , an endemic Javan sisorid fish. The comprehensive analysis involved 226 specimens collected from 10 rivers across three Java regions, obtained from the Museum Zoologicum Bogor (MZB). The Principal Component Analysis (PCA) and Discriminant Function Analysis (DFA) were used to analyze the collected morphometric data. In this study, the PCA showed overlap among populations, while DFA effectively identified population differentiation, showing the East Java (Brantas River) population as distinctly separate from the remaining regional groups. Furthermore, sub-regional analysis within West Java showed differences for the Cisanggarung and Cimanuk populations. The significant variations were reported in seven morphometric characters, including adhesive apparatus length (AAL), adhesive apparatus width (AAW), mouth width (MW), interorbital distance (Iod), eye diameter (ED), nasal barbel length (NBL), and snout length (SnL) and in eleven truss-based measurements (A-C, D-E, D-G, F-I, H-K, K-L, H-J, A-C, C-D, E-G, and J-K). This study provides valuable information for future investigations into the taxonomic status of G. platypogon , as well as for informing its ecological assessment within Java region.
Growth patterns, condition factors and morphological variations in Barbonymus schwanefeldii from Indonesia Y. Akmal, M. Yunus, H. Plumeriastuti, Y. Dhamayanti, M. Radhi, I. Irfannur, M. Muliari, I. Zulfahmi, A. S. Batubara, F. M. Nur Biosystems Diversity, 2025 Tinfoil barb ( Barbonymus schwanefeldii ) is one of Indonesia's native fish species which has economic value as a consumption and ornamental fish. This species is also found in the Leuser Ecosystem Area, specifically the Keureuto, Bunin, and Sikundur Rivers, Aceh Province, Indonesia. However, studies regarding the length-weight relationship, condition factors, meristics and morphometric variations of this species have not yet been undertaken , especially in the Leuser Ecosystem Area. So this research on these characteristics is important a s a basis for managing these fish in the Leuser Ecosystem Area. Samples were collected in three locations (Bunin River, Keureuto River and Sikundur River) over a period of nine months using nets, gillnets and fishing rods. Fish length and weight were measured in situ using digital scales and calipers. Meristic and morphometric analy s es were also performed in this study to reveal possible intraspecies differences. A total of 24 morphometric and 9 meristic characters were measured in this study. A total of 208 B. schwanefeldii samples were collected in this study with a total of 70 males and 138 females. The total number of B. schwanefeldii catches in the Keureuto, Bunin, and Sikundur River reach ed 57, 110, 41 samples, respectively. Based on the results of observations at the three research locations, it shows that female fish we re more dominant, where the ratio between male:female for the three locations respectively wa s between 1:2.33 (Bunin River), 1:1.71 (Keureuto River), and 1:1.56 (Sikundur River). B. schwanefeldii collected from the Keureuto River and Sikundur River had a negative allometric growth pattern, while those from the Bunin River had a positive allometric growth pattern. Comparative meristic and morphometric analysis showed that B. schwanefeldii collected from the Keureuto River and Sikundur River had high similarities, while B. schwanefeldii from the Bunin River w ere relatively different. The results of this research succeeded in revealing morphological variations between B. schwanefeldii popul a tions which are related to adaptation to different habitats.
SEA TURTLE CONSERVATION IN RANTAU SIALANG, INDONESIA: NESTING CHARACTERISTICS, HATCHING SUCCESS, EFFECTIVENESS AND LOCAL COMMUNITY PERCEPTION , Adli Waliul PERDANA, Ilham ZULFAHMI, , Dinda Winalda SYAM, , Ayu Nirmala SARI, , Firman Muhammad NUR, , Kizar Ahmed SUMON, , Badratun NAFIS, , Furqan MAGHFIRIADI, , Danielle Rodrigues AWABDI, and International Journal of Conservation Science, 2025 Sea turtle conservation efforts in Indonesia are regulated by several laws and government regulations. One of the embodiments of these laws and regulations is to provide the sea turtle conservation stations in various regions. However, studies related to the ecological characteristics of sea turtle habitat, the effectiveness of the sea turtle conservation station, as well as perceptions and attitudes of the local community toward sea turtle conservation, are still incompletely described. Hence, this study aims at monitoring the distribution and abundance of sea turtles, nest characteristics, program effectiveness, as well as community perceptions around the Rantau Sialang Sea Turtle Conservation Station, Indonesia. Data were collected from face-to-face interviews, direct observation and the station's administrative data. A total of 4,051 sea turtle eggs were successfully recorded during 2014-2020. The highest number of eggs was obtained in 2018, while the lowest was in 2014. Most sea turtle nest locations were distributed around the Rantau Sialang Sea Turtle Conservation Station. The diameter of the sea turtle nests ranged from 27 to 35cm. The slope of the nest ranged from 9 to 45°, while the depth ranged from 30 to 40cm. The performance of the Rantau Sialang Sea Turtle Conservation Station was categorized as effective with a score of 30. The parameters with the highest scores were the origin of eggs, hatchling release location, hatchling release time, sea turtle rearing facility and egg hatching facility. While the parameters with the lowest score were the hatching success and coastal monitoring. Taste, perception of its usefulness and local culture were the considerable reasons for consuming sea turtle eggs and meat in the local community around the sea turtle conservation station. This research provides valuable information that can be used as a basis for identifying threats to turtle populations in the Rantau Sialang conservation area.
Assessment of Fish Biodiversity of the Cimandiri Watershed, West Java, Indonesia Makara Journal of Science, 2025 Information on the fish biodiversity of the Cimandiri Watershed is incomplete, and human activities and anthropogen-ic impacts pose a significant threat to this biodiversity. The purpose of this study was to assess the biodiversity of fish in the Cimandiri Watershed. The results indicated that fish biodiversity in the area included 104 species belonging to 49 families. There were 26 species in the upstream area, 47 species in the middle area, and 61 species in the downstream area. Forty-three species were native to Indonesia, and 7 of the native fish were endemic to the area. There were 11 introduced species belonging to 6 families. Analysis of biodiversity status shows that 4 species were threatened, 2 spe-cies were near-threatened, 76 species were less considered, and 18 species have not yet been evaluated. Among the economically important species present, the eel is the most common in the Cimandiri Watershed. This study has re-vealed the profile of the Cimandiri Watershed, the characteristics of its ecosystem, fish biodiversity, economically im-portant fish species, the conservation status of fish species, and the threats to the fish biodiversity within it.
Growth patterns and condition factors of fish in the Celike River, leuser ecosystem area, East Aceh, Indonesia Adli Waliul Perdana, Furqan Maghfiriadi, Siti Maulizar, Al Julismi, Muhammad Dawami, Firman M. Nur Bio Web of Conferences, 2025 Fish growth patterns are the process of increasing the size and weight of a fish's body that occurs during its lifetime. This growth pattern is influenced by genetic factors, the environment, food availability and the physiological condition of the fish. Research on Growth Patterns and Condition Factors of Fish in the Celike River in the Leuser Ecosystem Area of East Aceh aims to determine the size of fish and provide an overview of fish growth patterns by analyzing the relationship between length and weight and fish condition factors. The method used is a purposive sampling method, namely determining the location of research station based on consideration of habitat characteristics in locations that are thought to have a high presence of fish, are easy to reach and represent the Celike River area in the Leuser Ecosystem Area. This research was carried out in July 2024. The total number of fish obtained was 122 individuals from 10 species belonging to seven families, namely Cyprinidae, Sisoridae, Clariidae, Channidae, Cichlidae, Balitoridae, Aplocheilus. There are two dominant species caught at this location, namely Tor soro and Tor tambra. Tor tambra obtained during the study amounted to 40 individuals with a total length of 70.09 - 434.4 mm and a weight of 3.96 - 811.05 g. Tor soro) obtained during the study amounted to 34 individuals with a total length of 61.79 - 144.33 mm and a weight of 2.89 - 32.5 g. The growth pattern of fish in the Celike River with eight fish species is negative allometric, two fish species are isometric and positive allometric, with condition factor values ranging from 0.07 to 8.88.
Landmark-based geometric morphometric and meristic analysis of body shape variation among Indonesian climbing perch Anabas testudineus (Bloch, 1792) populations A. Damora, M. Afrisal, K. Wibowo, F. M. Nur, H. Haryono European Zoological Journal, 2025 Fish stock assessments require a holistic approach that accounts for population heterogeneity, size range, sampling time frames, and habitat characteristics. However, these theoretical principles are often overlooked, potentially resulting in inappropriate fishery management decisions. This research aimed to evaluate (1) the spatial variation in the morphology of climbing perch (Anabas testudineus) across Indonesian populations using truss network analysis and (2) the temporal stability of these morphological traits over 90 years, assessed at 10-year intervals in habitats with varying ecological characteristics. The study analyzed 235 fish specimens from 20 Indonesian provinces, preserved at the Museum Zoologicum Bogoriense (MZB), Cibinong, Indonesia. Morphometric data were collected using the truss network method, measuring 19 distances between 10 anatomical landmarks with digital calipers. Nine meristic traits were recorded, including scale and fin spine/ray counts. Morphometric traits were standardized and analyzed using bivariate and multivariate statistical techniques. Based on the results of this study, population heterogeneity and the sampling time frame showed minimal influence on phenotypic variation, with a tendency for overlap between groups. Discrimination was observed among three islands – Sumatra, Kalimantan, and Sumba (with differences ranging from 2.1 to 2.39 mm) – as well as between the sampling periods <1970 and 1970–1980, with differences reaching up to 2.47 mm, and between the periods <1970 and 1980–1990, with a recorded difference of 2.36 mm. However, population and habitat characteristics had a significant effect on morphotype. Body depth and caudal peduncle shape significantly contributed to between-sub-population heterogeneity, while habitat characteristics were associated with all three body regions. These results demonstrate that the morphometric truss method can comprehensively evaluate fish population structure, with implications for decision-making to support sustainable fisheries management.
