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.

Abstract

Genus Mystus is widely distributed across Indonesia with eleven currently valid species. Three species are confirmed to inhabit Java Island: Mystus gulio, M. nigriceps, and M. singaringan. Due to their similar morphological appearances and relatively subtle diagnostic features, species identification and discrimination between these three species is somewhat challenging. This study evaluates the morphological differentiation of M. gulio, M. nigriceps, and M. singaringan at both interspecific and intraspecific levels using samples collected across Java Island. Morphological data including thirty morphometric and five meristic characters from 143 individuals in sampling sites were analyzed using Principal Component Analysis (PCA) and UPGMA clustering. PCA (75.32% total variance) effectively discriminated the three species, identifying maxillary barbel length and adipose-fin base length as the primary diagnostic characters. Intraspecific analyses revealed high morphological homogeneity across geographic sampling sites; however, significant phenotypic variance was observed, primarily attributed to ontogenetic allometric growth in juveniles and localized environmental plasticity. Despite testing for novel morphometric and meristic markers, this study reinforces the reliability of traditional adipose and barbel proportions as the definitive tools for field identification. These results provide a critical morphological baseline essential for the conservation, germplasm verification, and potential domestication of these indigenous aquatic resources. Highlighted Finding 1. Maxillary barbels and adipose fins are key diagnostic traits for Javanese Mystus2. PCA results reveal a unique morphological divergence in the Bogor M. singaringan3. Findings prioritize M. singaringan for farming and M. nigriceps for conservation Graphical View
