Abstract

Colour is an important indicator of ornamental fish beauty and value. The koi carp (Cyprinus carpio) is a valuable ornamental fish commodity and is in high demand because of its beauty, colour, and attractive body shape. Colour is an important factor in koi carp which are commonly red, white, yellow, black, or a combination thereof. One factor that can affect koi carp colour quality is the colour of the rearing tank background. This study aimed to determine the effect of rearing tank background colour on the brightness of juvenile koi carp (Cyprinus carpio). Research was conducted from October to November 2020 at the Laboratory of Water Quality and Aquatic Biota, Faculty of Animal Husbandry and Fisheries, Tadulako University, Palu. This study used a completely randomized design (CRD) consisting of 5 rearing tank background colour treatments (A = red; B = orange: C = purple; D = light blue; E = yellow) with 4 replicates. The variables observed were koi carp colour brightness TCF (Tocca Colour Finder) with values obtained from the average score given by the panellists analysed descriptively; absolute length and weight gain, with analysis of variance (ANOVA) at the 95% confidence level followed by the post-hoc Honestly Significant Difference (HSD) test using Minitab 16. Water quality and survival were analysed descriptively. From the results it was concluded that tank background colour had a significant effect on absolute length and weight gain. Colour was brightest under treatment B (orange tank background) and dullest under treatment E (yellow tank background). Survival rate was highest (100%) in treatment A (red tank background). Water quality parameters were in the optimum range for koi carp throughout the study.
