The research explores the impact of incorporating botanical additives as natural carotenoid sources in the feed on the pigmentation and growth performance of Indigo Barb (Pethia setnai), a popular tropical freshwater ornamental fish endemic to the Western Ghats. Four experimental diets, enriched with 10% Marigold, Beetroot, Hibiscus, and Spirulina respectively, were formulated and fed to captive-bred Indigo Barb over a 60-day period, with a control group receiving a basal diet. The study meticulously evaluated growth performance metrics and total carotenoid content in fish tissue. Results indicate that the Marigold diet outperforms others, displaying the highest carotenoid content (7.6µg/g) and fostering superior growth metrics. The study underscores Marigold as a potent natural carotenoid source for enhancing both coloration and growth in the Indigo Barb, contributing valuable insights to the field of ornamental fish nutrition.
