Spirulina plantesis flour supplementation to increase the growth and brightness of the color of Betta fish (Betta splendens) Regan, 1910

The cultivation of ornamental fish has not yet reached an
adequate level to consistently produce high color quality, which is a key
determinant of the fish's market value. This study aims to investigate the
Effect of Spirulina platensis, which is believed to contain carotenoids that
can enhance the color of freshwater ornamental fish, specifically Betta
splendens. A quantitative approach using a Completely Randomized Design
(CRD) experimental model was employed to test the hypothesis, with the
results analyzed statistically and described in detail. The study found that
treatment 2, involving a 1% concentration of Spirulina powder in artificial
feed, resulted in the best increase in color intensity, as indicated by a more
yellow and darker hue compared to the control, P3, and P4 treatments. The
study suggests that future research should include a larger sample size to
achieve optimal results.
