A checklist of native freshwater fish from Brantas River, East Java, Indonesia. Biodiversitas 23: 6031-6039. This study aims to provide information on the species composition second-largest river in All samples used this were caught activities during Fish Resource Survey (form May 5, 2021 August 20, 2022). Sampling was carried out four stations representing upstream, Karangkates Reservoir, midstream, and downstream. work recorded 42 divided into 35 genera 21 families. Cyprinidae dominant family, comprising 12 15 species. According IUCN Red List, most inhabiting River have a conservation status Least Concern (LC) or Data Deficient (DD), except for Rasbora lateristriata which is categorized as Vulnerable (VU). Genera Tor Neolissochilus are rarely found Javanese waters. We suggest that these should be reviewed. Information habitat use ecological interactions occurring needed urgently make appropriate decisions plans. Therefore, we more collections need studied river, well studies based eDNA analysis research incorporating both morphological molecular data.
