Molecular phylogenetic of silver barb barbonymus gonionotus (bleeker, 1849) (cypriniformes: Cyprinidae) in Java, Indonesia

Abstract

Barbonymus gonionotus is a species of cyprinid native to river drainages in southeastern Asia, which occurs in the Cambodia, Vietnam, Thailand, Laos and Indonesia. This study aims to identify the molecular phylogenetic of Barbonymus gonionotus in Java, Indonesia based on the Cytochrome C Oxidase Subunit I (COI) gene. Specimen from the Opak river had 656 base pairs with the Identity values 100% to Barbonymus gonionotus. The genetic distance of Barbonymus gonionotus in the Java was 0.000-0.005. Phylogenetic tree of Barbonymus gonionotus in the Java is provided.
