Biology, Ecology and Aquaculture potential of Osteochilus spilurus (Bleeker 1851) in East Belitung, Indonesia

Abstract

Osteochilus spilurus is one of the freshwater fish species in the Cyprinidae family which is found in the ancient river region of Sunda shelf which empties toward the North Natuna Sea. This article explores the biological, ecological, and potential characteristics of fish called Cempedik (local name in Belitung Island) as an aquaculture species. Research results and literature showed about feeding habits, reproduction, habitat, and aquaculture potential. It is abundant and well suited for culture in an established market insure, especially Belitung Island, but reproductive biology is not well understood. It can be preserved in an artificial environment, and it is possible to become aquaculture species as well as other osteochilus genera.

Morphological Comparative of Osteochilus spilurus (Cyprinidae) from Three Sundaland Island in Indonesia Using Geometric Morphometric

“…The harvesting of fish may impact the mating mechanism (Avise and Ayala, 2009). Most O. spilurus are captured in gonad-ripe conditions on Belitung Island (Rizkika, 2017; Kurniawan et al, 2020). Rather than phenotypic plasticity or environmental variation, phenotypic variations in harvested populations are due to evolution (Avise and Ayala, 2009).…”

“…These species' distribution is widely on a river in Sumatera, Bangka Belitung Archipelago, Malay Peninsular, dan Kalimantan (Roberts, 1989;Hui and Kottelat, 2009;Esa et al, 2012;Fahmi et al, 2015;Kurniawan et al, 2020). They do not have a common name and trade name but have various Indonesian names such as Cempedik, Kepaet, Bantak Batu, Aro, Buruk Perut, and Seluang.…”

LONG AND WEIGHT RELATIONSHIP TO FECUNDITY OF CEMPEDIK FISH (Osteochilus spilurus) IN CATCHING SEASON IN THE LENGGANG RIVER, EAST BELITUNG

“…Journal of Aquatropica Asia 7(1): 43-48 -44 - (Kurniawan et al, 2022). Adanya pola penangkapan, perdagangan dan konsumsinya menjadikan ikan ini lebih dikenal oleh masyarakat lokal di Belitung Timur dibandingkan daerah lain (Kurniawan et al, 2020). Kurniawan dan Triswiyana (2019) menyatakan lebih dari 79% masyarakat lokal Belitung Timur mengkonsumsinya dengan sebagaian besar diantaranya mendapatkan ikan dari perdagangan.…”

“…Ketersediaan jumlah dan kesesuaian pakan di alam, kondisi habitat tempat hidup, dan ukuran tubuh ikan memepengaruhi fekunditas (Oliveira et al, 2015). Osteochilus spilurus, yang teridentifikasi sebagai ikan pemakan fitoplankton (Kurniawan et al, 2020;Icas et al, 2019), sangat tergantung dengan ketersediaan jenis dan kelimpahan fitoplankton di perairan habitatnya. Pengamatan kelimpahan fitoplankton pada tahun 2016 menunjukkan nilai 3,710-8,676 individu / liter dengan indeks keseragaman antara 0,66-0,79 yang termasuk dalam kategori tingkat sedang.…”

Morphology and cytochrome b gene identification of Cempedik fish for ascertainment of domestication broodstock source in Belitung Island

“…The fishing season that occurs in the rainy season has the potential to disrupt the reproductive cycle of fish because the majority of fish caught are gonadally mature. More than half of the fish caught are at level 4 maturity [4]. Efforts to domesticate this species have been made.…”
