The research was aimed to evaluate the phenotypes profile of rasbora fish from Bangka Belitung Islands for aquaculture development. Samples of rasbora fish were collected from the rivers near Balunijuk Village, Bangka Residence. Three species of rasbora (Cyprinidae Family) which consisted of Rasbora einthovenii, Brevibora dorsiocellata, and Trigionopoma gracile. were collected. The truss morphometrics measurement was conducted to determine the phenotypic profiles of the three species. The results showed that the main identity characteristics to differentiate the three species were tail length (TL) and body width III (W-III). The highest survival rate was achieved by Brevibora dorsiocellata cultured in waters with pH 5-6 which was 93.30±5.80%. The lowest survival rate was attained by Trigonopoma gracile which was 76.60±5.80% cultured in pH 5-6 and 7. The Rasbora einthovenii cultured in waters with pH 5-6 showed the highest absolute weight gain compared to that of cultured in waters of pH 7. Brevibora dorsiocellata and Trigonopoma gracile tended to have better absolute weight and absolute length gain when cultured in waters with pH 5-6 compared to that of pH 7.
