The suitable temperature for breeding angelfish is essential as a commercial<br />

ornamental fish. The objective of this study was to determine the effect of temperature<br />

on reproductive performances and the growth rate of angelfish. 9 adult pairs (2.2-3.7<br />

g) of angelfish was grown for 30 days on three treatments, temperature 28°C, 31°C<br />

and 34°C. The reproductive Gonadosomatic Index (GSI), Hepatosomatic Index (HSI),<br />

fecundity, sperm concentration and egg diameter were measured. The data were<br />

analyzed by one way ANOVA and followed by Duncan post hoc test. Treatment 2<br />

(31°C) has better sperm concentration than treatment 1 (28°C) and 3 (34°C) (41-<br />

59%,p: 0.001). For male, there is no significant of three treatment for Weight Gained<br />

(WG) ranging from 15-16% (p: 0.955) and the Specific Growth Rate (SGR) (12-14%,p:<br />

0.718). The GSI of female on treatment 2 (31°C) and 3 (34°C) was better than<br />

treatment 1 (28°C) (0.01-0.03%,p: 0.049). Meanwhile, there is no significant on the<br />

HSI of female angelfish (0.01-0.02%,p: 0.207). As for fecundity, temperature 31°C<br />

and 34°C was better than 28°C (93-487%,p: 0.001). The egg diameter of temperature<br />

of 31°C is significant compared to 28°C and 34°C (p: 0.001.). For female, there is no<br />

significantly different for Weight Gained (WG) ranging from 11-14% (p: 0.837) and<br />

the Specific Growth Rate (SGR) ranging from 9-13% (p: 0.851). As compared to the<br />

value, the 31°C are the best temperature for the reproduction and growth rate of<br />

angelfish.<br />
