Abstract

Manggar Reservoir functions as both a rainwater catchment and the main raw water source for Balikpapan while also supporting local subsistence fishing activities. This community-based fishing is primarily aimed at fulfilling household nutritional needs rather than for commercial purposes. The objective of this study was to elucidate the species composition, abundance, and diversity of ichthyofauna in the Manggar Reservoir. The study was conducted between May and June 2024, and species identification was performed at the Hydro-Oceanography Laboratory of the Faculty of Fisheries and Marine Sciences, Mulawarman University. The ichthyofauna were sampled using a purposive random sampling technique. The ichthyofaunal specimens captured and identified belonged to six families, nine genera, and 10 species. The species diversity index (H’) was calculated as 1.216. The highest diversity index was observed at station KM 15 (1.24), while the lowest was recorded at station KM 23 (0.76). The evenness index (E) was 0.528, indicating a moderate degree of species distribution. The dominance index (C) was 0.346, suggesting moderate dominance and implying that no single species exhibited overwhelming dominance within the ecosystem. Barbodes strigatus exhibited the highest relative abundance, representing an average of 46.39% of the total catch across all sampling stations, it was found 15,315 individu, followed by Channa micropeltes with an abundance of 31.42%.
