Abstract

Guppies are ornamental fish that have economic value and can be cultivated. One of the problems in guppies cultivation is the poor quality of body color. The solution to this problem is to improve the environmental quality in guppy aquaculture. This study evaluates changes in color quality, behavioral response, and blood glucose levels of guppies using water immersion of Indian almond leaves on rearing media. Study was carried out using a completely randomized design consisting of five treatments. The rearing media was filled water with a total volume of 10 L from each treatment with different concentrations, namely, Control treatment (100% freshwater), A (75% freshwater + 25% Indian almond leaf water), B (50% freshwater + 50% Indian almond leaf), C (25% freshwater + 75% Indian almond leaf) and D (100% Indian almond leaf). Each treatment observed several test parameters such as color quality percentage, survival rate, chromatophores cells number, behavior, glucose levels, and the water physical-chemical parameters. Guppies' behavioral responses, in general, experienced an increasing change in each treatment for seven days. The highest color quality percentage by treatment D was 73.93±2.29%, and the highest glucose level was by the control treatment, which was 24.11±0.41 mg dL-1. The results of variance analysis showed that the water immersion of Indian almond leaves was significantly different on color quality, behavioral response, and blood glucose levels through Duncan's test (p<0.05).
