Abstract

Barbodes sellifer merupakan merupakan ikan air tawar dari keluarga cyprinid. Spesies ini pertama kali dideskripsikan pada tahun 2021 oleh Kottelat dan Lim. Saat ini spesies Barbodes sellifer dapat ditemukan di Singapore dan malaysia. Di Indonesia sendiri barbodes sellifer ditemukan di Sumatera, Kepulauan Riau hingga pulau Natuna. Kehadiran Barbodes sellifer di Kepulauan Bangka merupakan catatan baru. Meskipun spesies ini dapat ditemukan di Pulau Bangka, namun jumlahnya tidak banyak, sehingga perlu dilakukan upaya-upaya domestifikasi untuk mempertahankan populasi. Agar kegiatan domestifikasi dapat berjalan dengan baik, perlu melakukan beberapa penelitian mendasar yang salah satunya adalah studi morfometrik dan meristik untuk memastikan validasi spesies dan sebagai dasar untuk penelitian-penelitian selanjutnya. Dalam penelitian ini kami melakukan analisis karakter morfometrik dan meristik spesies Barbodes sellifer yang ditemukan di Pulau Bangka dan sebagai langkah awal dalam proses domestikasi. Hasil studi karakter morfometrik menujukan panjang total (TL) 7,4 cm, panjang standar (SL) 6,0 cm, tinggi kepala (HD) 1,0 cm, diameter mata (ED) 0,5 cm, tinggi badan (BD) 2,0 cm, panjang sirip ekor bagian atas (LUCL) 1,2 cm, panjang sirip ekor bagian tengah (LMCL) 0,8 cm, panjang sirip ekor bagian bawah (LCLL) 1,6 cm. Sedangkan meristik spesies Barbodes sellifer yaitu jari-jari sirip punggung memiliki rumus D.I-II.7, jari-jari sirip anal memiliki rumus A.6, Jari-jari sirip dada memiliki rumus P.I-II.10, Jari-jari sirip perut memiliki rumus V.I.7. Ikan barbodes sellifer memiliki tipe mulut terminal,bentuk tubuh compressed, tipe sisik ctenoid dan bentuk ekor forked. Berdasarkan karakter morfologi dan ciri khusus jenis Barbodes sellifer yang ditemukan dialiran sungai Jada Bahrin juga termasuk spesies Barbodes sellifer yang ditemukan di Singapura.

Abstract

Bangka Island is one of Indonesia’s regions with significant potential in terms of freshwater fish diversity, particularly within the genus Betta, commonly known as wild bettas. This study aims to document species diversity, geographic distribution, and natural habitat characteristics of wild Betta populations on Bangka Island, which inhabit peat swamp ecosystems, blackwater rivers, and abandoned tin-mining ponds. Through field exploration and morphological identification, seven primary Betta species were recorded: Betta burdigala, B. schalleri, B. edithae, B. chloropharynx, B. uberis, B. cracens, and B. simorum. Each species occupies a distinct habitat type characterized by extreme water parameters, including low pH (4.2–5.8), minimal dissolved oxygen levels (0.8–2.5 mg/L), relatively stable water temperatures (26–30°C), and low conductivity. Certain species, such as B. burdigala and B. chloropharynx, exhibit unique physiological adaptations via the labyrinth organ, which enables aerial respiration. The species distribution is uneven across the island, with some species being restricted to specific localities, rendering them endemic. Major threats to these species include habitat degradation due to tin mining, oil palm plantation expansion, and environmental pollution. Recent data indicate that several populations are experiencing severe declines, with some nearing local extinction. Consequently, the findings of this study provide a critical foundation for ecosystem-based conservation strategies and the restoration of vital habitats. Scientifically, Bangka Island qualifies as a Betta biodiversity hotspot of strategic importance in the context of Southeast Asian biogeography and the conservation of endemic freshwater species.

Abstract

Freshwater fish biodiversity in Belitung Island has undergone a significant decline due to extensive tin mining activities and the rapid expansion of oil palm plantations. In response to these ecological pressures, a biodiversity assessment was conducted in 2024 in the Lenggang River system—an ancient freshwater ecosystem located in East Belitung, Indonesia. The primary aim was to document native and endemic fish species and to establish a reintroduction-based conservation strategy tailored to the river's ecological context. Field surveys recorded high ichthyofaunal diversity, from which 32 native species were selected for reintroduction based on ecological value, conservation status, endemism, and their capacity to adapt to rehabilitated habitats. Among the prioritized taxa was Gymnochanda verae, a rare and endemic species found exclusively in the Bangka–Belitung region. Other selected species include Gymnochanda verae, Desmopuntius gemellus, Osteochilus spilurus, Osteochilus flavicauda, Eirmotus insignis, Brevibora cheeyai and Aplocheilus armatus. The reintroduction initiative was designed not only to restore declining populations but also to enrich the genetic diversity of native fish communities. Importantly, all reintroduced species were confirmed to be historically present and indigenous to the Lenggang River system. The conservation strategy was further supported by habitat restoration, local community involvement, and long-term population monitoring. Preliminary results indicate positive acclimatization in restored zones, underscoring the potential of species reintroduction as an effective tool for freshwater biodiversity conservation in ancient tropical river systems. This study provides essential baseline data and offers a replicable model for integrated conservation of freshwater ecosystems in Southeast Asia.
