Abstract

Central Sulawesi has a diverse diversity of ichthyofauna. Gobies are one type of fish abundant in fresh water and can be found from the upstream to the downstream of the river. The abundance and information on the types of gobies are still limited in several rivers in Central Sulawesi. Tolitoli Regency is one of the areas that still has minimal information on the diversity of gobies, so it is necessary to research collecting gobies in the watershed in Tolitoli Regency. The research was conducted from July 2020 to December 2020 in the watershed of Baolan District (Dadakitan Village, Buntuna Village, and Tambun Village), Tolitoli, Central Sulawesi. The sampling locations in the watershed are divided into 3 parts, namely the upstream, middle, and downstream. Gobies were collected using the pore sampling method by preparing eight observation stations. Specimens were collected using nets (size 20 x 20 cm) with the method of catching against the current. The caught fish were kept in a mini aquarium and then documented using a digital camera. Furthermore, the fish were preserved using 70% alcohol for identification. The results of the study showed that the collection of goby fish in the Tolitoli watershed, Central Sulawesi, was found to be 408 individuals consisting of 4 families (Butidae, Eleotridae, Gobiidae, Oxudercidae), 12 genera (Butis, Oxyeleotris, Belobranchus, Eleotris, Giuris, Redigobius, Awaous, Lentipes, Stiphodon, Sicyopus, Sicyopterus), and 16 species (Butis sp., Redigobius sp., Sicyopterus sp., Stiphodon semoni, Stiphodon sp., Awaous sp., Belobranchus sp., Schismatogobius sp.1, Schismatogobius sp.2, Eleotris fusca, Oxyeleotris sp., Giuris sp., Sicyopus zosterophorus, Sicyopus sp.1, Sicyopus sp.2, Lentipes sp.). The highest abundance of goby fish species in the Tolitoli Watershed is Stiphodon semoni (47,79%).  Keywords: Amphidromus, sustainability, aquatic organisms.

Abstract

The Tuweley River is an aquatic ecosystem rich in biodiversity. One of the fish species found in this river is Redigobius. Studies on this species' molecular and morphological aspects are very important to support conservation efforts and management of local aquatic resources. This research was conducted from September 2022 to March 2023. The specimen collection is in the Tuweley River, Tolitoli Regency, Central Sulawesi Province, Indonesia. Morphological character measurements were carried out at the Integrated Laboratory of Universitas Madako Tolitoli, while DNA (Deoxyribonucleic Acid) analysis was carried out at the Bionesia Laboratory, Bali. This study employs a quantitative descriptive approach to analyze the data. The data examined include morphological and molecular characteristics (qualitative) and quantitative data consisting of morphometric, meristic characters, and DNA analysis of R. tambujon. These data were tabulated in table form and analyzed descriptively to obtain a comprehensive overview of the species' characteristics. The study results showed that the fish collected in the Tuweley River were the R. tambujon species, based on DNA analysis and morphological character measurements.
