Abstract

The research was carried out aiming to report for the first time the presence of Oreochromis niloticus on Belitung Island (Indonesia), updating the invasion range of this species. The presence of non-native fish can have a negative impact on aquatic species communities through competition for resources, predation, hybridization, habitat modification, disease transmission (infection or parasitism), and genetic effects. We carried out an expedition to obtain O. niloticus specimens on January 20 and 25 2023, around six O. niloticus specimens were caught in the Lenggang River, Lenggang Village, Gantung District, East Belitung Regency, Belitung Island, Indonesia. Results from observations of meristic and morphological characteristics led to several specimens collected on Belitung Island being identified as Oreochromis niloticus. Discovery of O. Niloticus in the Lenggang River, as a new record representing the species' invasion range approximately 226 km to the east of Bangka Island. The discovery of this species contributes to understanding the extent of expansion and invasion of O. niloticus in Indonesia. This information is very important for classifying and determining river conservation strategies, as well as for planning efforts to protect ecosystems, especially from non-native species that have the potential to become invasive species.

Abstract

This study aims to report the presence of Tilapia Tilapia Oreochromis niloticus on Bangka Island (Indonesia) for the first time and update the invasion range of this species. Previously, this species had invaded various areas in Indonesia such as Sumatra, Java, and Sulawesi. The presence of Invasive Nila Tilapia can have a negative impact on aquatic biota through food competition, predation, and disease transmission. A total of 30 tilapia specimens were caught using Anco's fishing gear which was installed for 2 minutes consisting of mature and seeds, ranging in size from 20mm to 90mm in the Mang Kalok River, Rebo Village, Bangka Induk Regency, Bangka Island, Indonesia through a field expedition on June 11, 2023. A description of the morphological characters of the captured specimens is provided in the discussion.

Abstract

Sepuluh jenis ikan yang dijumpai di perairan Tebat Rasau merupakan iktiofauna eksotik yang berpotensi menjadi ikan endemik Pulau Belitung. Hingga saat ini, masih minim kajian pada spesimen yang berstatus konservasi hampir punah maupun yang berstatus least concern ini. Penelitian ini mengkaji pada iktiofauna eksotik di Tebat Rasau, Desa Lintang, Belitung Timur menggunakan metode deskriptif eksploratif. Sepuluh jenis ikan dijumpai di perairan Tebat Rasau yang memiliki kondisi perairan dengan pH 5,73, suhu 26,1oC dan oksigen terlarut 11,4 ppm. Perairan di Tebat Rasau memiliki substrat gambut dan banyak ditumbuhi Pandaus sp. yang menutupi sebagian badan perairan. Terdapat lima jenis ikan dari perairan Tebat Rasau yang tidak dijumpai pada penelitian sebelumnya, yaitu Ikan Arwana (Scleropages formosus), Ikan Gurame Cokelat (Sphaerichthys selatanensis), Ikan Temeliyongan (Chaca bankanensis), Ikan Gurami Paros (Parosphromenus cf bintan) dan Ikan Bebidis (Brevibora cheeya).
