Abstract

Members of the Adrianichthyidae family share typical distributions, as does the javanicus group, which inhabits western parts of Southeast Asia. Javanicus group members, specifically Oryzias javanicus and Oryzias hubbsi, is the only Adrianichthyidae species that can be spotted in Sundaland Indonesia. Morphological identification and the species distribution mapping of Oryzias specimens from Sundaland in this study were interpreted using ecoregional and dendogram tree approach. Specimens were collected from 11 areas representing five ecoregions in Sundaland Indonesia. Specimens were collected from islands of Java, Sumatra, Belitung and Kalimantan. Six individuals from each population of Oryzias were sampled for morphological identification. Specimens collected from estuaries were morphologically identified as O. javanicus and specimens from freshwater identified as O. hubbsi. Distribution of O. hubbsi from Salatiga is the first record from Central East Java (CEJ) ecoregion, which was previously only distributed in Southern Sumatra-Western Java (SWJ) ecoregion. Morphology of O. hubbsi from Sundaland Indonesia has mean of Standard Length (SL) 1.56 cm, Total Length (TL) 1.94 cm, Anal rays (A) 16, Pectoral rays (P) 8, and Dorsal rays (D) 6. Meanwhile, morphology of O. javanicus from Sundaland has mean of SL 2.07 cm, TL 2.56 cm, A 22, P 11, and D 6.

Abstract

Mastacembelus sp., a member of the Mastacembelidae family, is distributed across Java, Sumatera, and Kalimantan. Mastacembelus, locally named berod fish in the Brantas River lacks population’s descriptions and morphological analyses. Morphological analyses, including morphometric and meristic descriptions, are important for precise identification and classification of kinship relationships, serving as a cornerstone in the fields of biology, taxonomy, and conservation. This study aimed to conduct a comprehensive morphometric and meristic identification of the berod fish population in the Brantas River, East Java. A total of 37 samples were collected from 6 different locations: Blitar, Tulungagung, Kediri1, Kediri2, Nganjuk, and Mojokerto. The morphometric measurements were based on 25 characters, while the meristic calculations were based on 6 characters. The data analyzed with PCA and CA using SPSS and PAST programs. The results revealed that berod fish in the Brantas River had morphological characters belongs to the Mastacembelus unicolor. However, notable disparities were observed in meristic characters, particularly in the Dorsal Fin Spines (DFS). PCA analysis showed significant differences in morphometric characters but not supported by meristic characters. These results underscore the importance of integration both morphological and meristic analyses for a comprehensive understanding of the berod fish population.
