Abstract

The potential of freshwater fisheries in local species such as hampal fish (Hampala macrolepidota) presents several research gaps, particularly in specific localities. Research on H. macrolepidota in East Java may serve as a foundation for future management and development of local species, especially given that H. macrolepidota aquaculture is rarely carried out. Morphological studies based on meristics and morphometrics can be used for broodstock selection in H. macrolepidota domestication efforts. In this study, 21 Hampala specimens were assessed based on morphometrics and meristics, and analysed using a significance test, PCA and dendrogram. The analysis results by PCA and dendrogram showed morphometric differences in the Probolinggo and Banyuwangi populations compared with the four Brantas River populations. In contrast, based on meristics, the entire population does not show apparent differences based on the population. The clear differences demonstrated in the Probolinggo and Banyuwangi populations morphometrically indicate local adaptation due to differences in water conditions.

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.

Abstract

Ikan kotes (Channa gachua) dan ikan kutuk (Channa striata) adalah spesies dari famili Channidae yang tersebar secara alami di perairan Indonesia. Kedua spesies tersebut memiliki nilai ekonomi yang tinggi karena beberapa alasan, yaitu sebagai sumber protein bagi masyarakat setempat, memiliki kandungan albumin yang penting bagi kesehatan manusia, serta belakangan ini menjadi populer sebagai ikan hias. Penelitian ilmiah dasar seperti studi filogenetik penting untuk dilakukan guna mendukung upaya domestikasi maupun konservasi. Di penelitian ini, kami melakukan koleksi spesimen C. gachua dan C. striata dari beberapa lokasi berbeda di Jawa Timur untuk menjelaskan posisi filogenetiknya di antara spesies lain dari genus Channa. DNA mitokondria gen sitokrom c oksidase subunit I (COI) dari satu perwakilan individu untuk setiap lokasi telah diurutkan dengan metode sequencing. Dalam melakukan analisis filogenetik, sekuens DNA untuk banyak spesies dari genus Channa diperoleh dari penelitian sebelumnya. Pohon filogenetik maximum likelihood menunjukkan bahwa individu C. striata dari Jawa Timur mengelompok bersama dan membentuk clade dengan nilai bootstrap yang sangat tinggi (100%). Sebaliknya, C. gachua dari Jawa Timur berkerabat jauh dengan C. gachua dari Jawa Barat dan Kanchanaburi, Thailand, dengan divergensi genetik yang tinggi dengan jarak genetik > 2%. Hasil ini selaras dengan penelitian sebelumnya yang menunjukkan bahwa C. gachua merupakan spesies kriptik yang terdiri dari dua spesies atau lebih. Penelitian lebih lanjut perlu dilakukan, misalnya mengenai keragaman genetik, struktur populasi, dimana data dapat digunakan untuk merancang manajemen konservasi atau program pemuliaan yang efektif untuk kedua spesies tersebut.
