Effect of different container colors on the growth and survival rate of guppies (Poecilia reticulata) in the juvenile phase

The purpose of this study was to determine the effect of different container colors on the growth and survival rate of guppy fish (Poecilia reticulata) in the juvenile phase. This research was conducted at the SUPM Kupang Hatchery Teaching Factory Facility which is located in the government area of West Kupang District. This research design uses a completely randomized design (CRD) where there are 4 treatments with each treatment having 3 replicates. The variables observed during this study were weight growth and survival rate of fish. Observations of weight growth and survival rate of fish were carried out in an interval of 10 days. Body weight gain (BWG), body weight increase (BWI) and specific growth rate (SGR) for each treatment during 40 days of maintenance showed results that were not significantly different (p>0.05). The first highest weight growth results were obtained in the clear colored container treatment with values of 0.008±0.006 g BWG, 0.31±0.26g BWI and 0.77±0.006% SGR, respectively. The second highest growth was obtained in the red container treatment with a value of 0.006±0.03 g BWG, 0.25±0.13 BWI and 0.62±0.003% SGR. This was followed by the yellow colored container treatment with values of 0.005±0.001 g BWG, 0.20±0.05 g BWI and 0.50±0.001 % SGR. The lowest weight growth value was obtained in the black colored aquarium treatment with values of 0.004±0.001 g BWG, 0.15±0.04 g BWI and 0.36±0.001 % SGR. The highest result for the survival rate was obtained in the black colored container treatment with a value of 89%. While the lowest value was obtained in the clear colored container treatment which was 50%. The second and third highest survival rates were obtained in the yellow and red colored container treatments with values of 72% and 67%.
