Effect of Use of Different Light Spectrum on Growth Performance and Color Brightness Level of Tiger Barb (Puntius tetrazona)

This study aims to evaluate the effect of light spectrum on growth performance and brightness level of tiger barb (Puntius tetrazona). The research was conducted in January – March 2022 at the Laboratory of Aquatic Animal Physiology, Faculty of Fisheries and Marine Sciences, Padjadjaran University. This study used an experimental method of Completely Randomized Design (CRD) with five treatments and three replications. The treatment consisted of five treatments, namely control (without LED lights), white LED lights (B), red (C), green (D) and blue (E) lights with 12 hours of irradiation. The treatment was given for 60 days. Parameters observed included growth in length and absolute weight, color brightness level, survival rate and water quality (temperature, pH and DO). The results of the study for 60 days of maintenance showed that the best growth parameter was the red LED light treatment with an absolute length growth of 0.57 cm and an absolute weight growth of 0.49 g. The best color quality parameter for tiger barb (Puntius tetrazona) was obtained in the red LED light treatment with an increase in the color score in the Toca color finder (TCF) reaching 1.7 on the body; 2,3 on the pectoral fins; and 2.4 on the tail. The water quality parameter values are in normal conditions (temperature ranges from 27.3-27.9 ◦C; DO ranges from 4.2-5 mg/l; and pH ranges from 6.97-7.65;) so that it is good for the survival rate of tiger barb, namely 100%.
