Abstract

This study evaluated the effects of red light-emitting diode (LED) exposure on the production performance of comet goldfish (Carassius auratus). A completely randomized design was applied with two treatments and three replicates. The treatments consisted of red LED light exposure for 12 h day⁻¹ and a control group maintained under ambient room light. The experiment was conducted for 42 days. Production performance data were analyzed using one-way analysis of variance (ANOVA), whereas water quality was described as the range of values observed during rearing. The results showed that red light exposure did not significantly affect production performance compared with the control treatment (P > 0.05), including biomass gain, absolute weight and length growth rates, feed consumption, feed conversion ratio, and survival rate, although mean biomass gain, feed consumption, and survival rate tended to be higher under red light. Water quality in both treatments remained within the range tolerated by comet goldfish. Red LED exposure for 12 h day⁻¹ over 42 days therefore did not improve the production performance of comet goldfish. Further studies are recommended to evaluate the effects of different light spectra on the production performance of ornamental fish.
