This research was aimed to examine the habitat characteristics, growth patterns and condition factors of T. tambra in the Mamis River, Leuser Ecosystem Area, Aceh, Indonesia. This research was conducted on the Mamis River in three different river conditions from July to August 2023. The ecological parameters of T. tambra were conducted by observing the main, broodstock, spawning, and nursery ground habitats based on diversity of catch size at a location, water quality, aquatic substrate, aquatic vegetation, and water shade. The growth pattern parameter was also analysed to reveal the condition of T. tambra. The T. tambra habitat in the Mamis River includes broodstock and spawning habitat with the criteria from small to large rocks overgrown with Bryophytes, gravel and sand substrates, clear water color, slow to swift water currents, and river environment. Most of it is primary forest. In the main habitat, there is dominant riparian vegetation in the form of forest timber trees such as Pometia pinnata, Ficus fistulosa, Hydnocarpus castanea, and Aglaia tomentosa. The habitat for the juvenile is in the form of rocks, gravel substrate, clear water color, and fast water currents. In the nursery habitat, the dominant riparian vegetation is Balakata baccata. Based on the results of the water quality analysis at the three stations show that temperature, pH, DO, currents, BOD, COD are significantly different, but brightness levels are not significantly different. The analysis of the length-weight relationship shows that the condition of the fish is stable, and sufficient food is available. © 2024 Faculty of Fisheries and Marine Universitas Airlangga.
