Glyptothorax spp., locally known as Ali-ali, is a native freshwater fish in the Jambo Aye subwatershed, Wih Delong, Bener Meriah, Aceh, Indonesia. This study assessed its feeding ecology and selected ecological traits from December 2023 to February 2024. Sampling was conducted at three habitat-representative stations using gill and cast nets, yielding 90 individuals. Stomach content analysis revealed a predominantly carnivorous diet, dominated by crustaceans (72 degrees%o), followed by macrozoobenthos (19 degrees%o) and detritus (9 degrees%o), with Index of Preponderance exceeding 40 degrees%o, confirming crustaceans as principal prey. Length-frequency analysis identified eight size classes, with mean lengths highest at the plantation station (130.95 mm) and lowest in the forest station (92.19 mm). Mean relative gut length (RGL = 0.6 TL) supported carnivorous classification. Trophic niche breadth ranged between 1.30-2.17, indicating moderate resource-use variation. Length-weight relationships showed negative allometric growth (b<3) and strong positive length-weight correlations (r = 0.695-0.979). Findings indicate stable trophic positioning, spatial size variation, and growth patterns reflecting adaptation to heterogeneous headwater habitats.

Abstract This study aims to determine the effect of using industrial wastewater as a maintenance medium on the growth performance and histological description of the liver and gills of catfish. The study was conducted with a completely randomized design (CRD) using five treatments of wastewater and clean water concentrations (0%, 25%, 50%, 75%, and 100%) for 40 days. The parameters observed included survival, absolute weight and length growth, feed conversion ratio, gill and liver organ histology, and water quality. The results of this study indicate that the use of wastewater as a maintenance medium has a significant impact on the growth performance of catfish. Microscopic observation of gills and liver tissues showed different histopathological changes in fish exposed to wastewater. Histology results showed the most severe damage in P5 treatment with clinical symptoms in the gills (Edema, Desquamation, Fusion of lamellae, and Inflammatory cell infiltration) and liver (Microvacuolar steatosis, Hepatic sinusoids and Inflammatory cell infiltration). Exposure of treatments showed significant increase in Zn content on whole body.

Bostrychus cf. sinensis, a member of the family Eleotridae, was first identified in the Muara Telang region, Banyuasin, South Sumatra. Specimens collected from tidal channels were subsequently analyzed genetically using DNA barcoding with the Cytochrome Oxidase Subunit 1 (COI) gene. The molecular analysis revealed that the Muara Telang specimens shared 98.55% genetic similarity with Bostrychus sinensis from the Seom River, South Korea. According to genetic guidelines, a divergence greater than 3% may indicate a distinct species. The genetic divergence observed was 0.243, equivalent to 243 nucleotide variations out of 1,000 bases analyzed. Phylogenetic analysis showed that Bostrychus cf. sinensis from Muara Telang clustered within the same clade as Bostrychus sinensis but still exhibited genetic polymorphism at 8 distinct sites. Therefore, this specimen was designated as Bostrychus cf. sinensis. The COI gene sequence data for Bostrychus cf. sinensis from Muara Telang have been deposited in GenBank under accession MK777294.1.

Understanding the environmental factors associated with reef-associated fish habitat suitability is important for conservation planning in tropical archipelagic systems, where temperature, nutrient dynamics, productivity, and water quality interact across space and time. This study examined temporal changes in predicted habitat suitability for reef-associated fish across Indonesian waters from 2000 to 2023. Occurrence records were spatially thinned and modeled using MaxEnt with target-group background selection to reduce sampling bias. Model calibration was performed by comparing regularization multiplier values, and RM = 2 was selected for the final models. Four six-year periods were analyzed using satellite-derived oceanographic predictors representing thermal conditions, nutrients, productivity, salinity, dissolved oxygen, and suspended particulate matter. Model performance was consistently good, with mean test AUC values ranging from 0.841 to 0.900. Nutrient-related and water-quality variables were the most influential predictors of relative habitat suitability. Suspended particulate matter was the strongest contributor in T1, whereas dissolved iron dominated during T2-T4, followed by phosphate. Temperature variables contributed less than nutrient-related predictors, suggesting that reef-associated fish suitability in Indonesian waters is strongly associated with regional biogeochemical and water-quality gradients. Predicted suitable area showed a non-linear temporal pattern, declining from T1 to T2 before increasing in T3 and T4. However, these patterns should be interpreted as changes in relative environmental suitability, not direct evidence of population recovery or ecosystem resilience. These findings highlight the importance of integrating water-quality management, watershed control, reef monitoring, and field validation when using broad-scale habitat suitability models to inform reef fish conservation in Indonesian waters.

The snakehead fish (Channa striata), a native freshwater species of Indonesia, is highly valued on the market and has been successfully cultivated. The purpose of this study is to determine the optimal dosage of probiotics and turmeric combination that can improve the growth and survival of farmed snakehead fish. The present study employed a fully randomized design, incorporating four treatments and three replications. The probiotics and control mixtures were administered at a dose of 0 mL/kg feed (P0), 15 mL/kg feed (P1), 30 mL/kg feed (P2), and 45 mL/kg feed (P3). Water quality, feed conversion ratio, daily growth rate, and survival rate were among the attributes assessed in the present study. Statistical analysis was performed using SPSS version 25.0 with a 95% confidence interval. The results indicate that probiotic therapy supplemented with turmeric exerts minimal effect on the growth performance or survival rate of snakehead fish (P > 0.05). The administration of probiotics containing turmeric did not improve the growth or survival of domesticated snakehead fish raised for a duration of 60 days. Further research is needed to determine the effect of administering a combination of probiotics and turmeric on the survival and growth of snakehead fish raised for a minimum of 120 days.

Abstract. Nasution MA, Najmi N, Hermi R, Lubis F, Lisdayanti E, Saputra F. 2025. Influence of reef cover classes on functional diversity of reef fish in the Banyak Islands Marine Nature Park, Aceh Province, Indonesia. Biodiversitas 26: 4346-4362. Coral reefs are critical marine ecosystems that are increasingly threatened by human and environmental pressures, prompting research into how habitats shape biodiversity. This study explored how seven reef cover classes: reef slopes, sheltered reef slopes, reef crests, reef flats, plateaus, backreef slopes, and lagoons, influence reef fish functional diversity in the Banyak Islands Marine Nature Park, Aceh Province, Indonesia. Using underwater visual censuses across 20 sites with 60 belt transects (250 m² each), we surveyed 131 reef fish species at 3-12 m depths. We measured four functional diversities of reef fish: Functional Richness (FRic), Functional Divergence (FDiv), Functional Evenness (FEve), and Rao’s Quadratic entropy (RaoQ). Bayesian multivariate models revealed that reef slopes, sheltered reef slopes, and reef crests significantly influenced functional diversity, explaining 2-55% of variance, average 28.5%. Reef slopes showed the strongest effects, positively influencing FEve (posterior probability: 0.95) and RaoQ (posterior probability: 0.99), indicating balanced trait distribution and enhanced functional diversity in structurally complex habitats. However, reef slopes negatively affected FDiv (posterior probability: 0.89). Reef slopes notably boost RaoQ and FEve, reflecting balanced trait distribution and diverse ecological roles. The effects on functional richness and divergence were less pronounced, indicating limited trait range expansion. This study reveals that certain reef formations play a crucial role in maintaining healthy aquatic ecosystems, which is vital for conservation efforts in less-than-ideal reef environments.

Goonch (Bagarius yarelli) is one of the local fish species affected by dynamic changes due to activities along Perjaya Dam. The first component in conducting the cultivation of local fish is domestication The main problem in domestication is the adaptation of wild fish to the controlled environment. Another aspect that needs to concern in domestication is the defense of domesticated species from several pathogens, especially parasites because most of wild fish captured from natural habitats are attacked by several parasites. This study aimed to determine the prevalence and intensity of ectoparasites attacked goonch captured from Perjaya Dam. The sampling method used was purposive sampling method and followed by laboratory examination. A total number of 90 goonch were collected using fishing rods and gillnets with an aid from local fishermen during this study. Ectoparasites were examined on several external organs including skin or scales, fins, and gills. Ectoparasites found during the sample examination were recorded for further calculation of ectoparasites types, prevalence, and intensity. The measurement of water quality parameters was performed after sample collection. Water quality parameters measured consisted of temperature, pH, dissolved oxygen, ammonia, and transparency. Goonch captured from Perjaya Dam were infested by Lernaea sp. and Gyrodactylus sp. through single infestation and with the same prevalence level (1.11%). Lernaea sp. showed a higher intensity (52 ind/fish) on goonch than that of Gyrodactylus sp. (1 ind/fish). Almost all water quality parameter in sampling site, including temperature, pH, and dissolved oxygen, were in normal ranges to support the live of freshwater fish.

Seagrasses are important marine plants that provide a variety of ecosystem services, including food and shelter for marine life, and protection from coastal erosion. This study investigated the biodiversity (alpha and beta diversity) of seagrass in the Kepulauan Banyak Marine Nature Park, Indonesia, with a specific focus on eight sites. Alpha diversity was calculated using Shannon's index, Simpson's index, and Pielou evenness. Beta diversity was determined using Bray-Curtis dissimilarity and Jaccard dissimilarity allowing us to examine the variations in species composition among different sites. Principal coordinate analysis and Partial distance-based redundancy analysis was used to visualize and investigate the impact of constraint variables to the structure of the seagrass communities. Alpha diversity varied among the sites, with the highest alpha diversity found at the Orongan and Matahari site and the lowest at the Ujung Lolok and Balai sites. The dominant substrate type (mud or sand) was found to be a significant (P≤ 0.01) determinant of seagrass alpha diversity, with mud substrates supporting higher diversity than sand substrates. The relationship between alpha diversity and constrain variables was only significant with closest distance to forest lost and longitude variables. The analysis found that water pH, closest distance to forest lost, mean distance to tourism spots, and closest distance to settlement collectively explained a significant (P≤ 0.001) portion (88.48%) of the variation in beta diversity of seagrass across the sites. The results of this study can be used to develop management strategies for the conservation of seagrass meadows in the park.
