"Assessing The Efficacy Of Spirulina Algae-Based Feed For Goldfish (Carassius Auratus) And Black Molly (Poecilia Sphenops)"

Abstract
Abstract:
Spirulina sp a type of cyanobacteria characterized by its spiral shape. Spirulina is comprised of 60% vegetable protein, essential vitamins, and β-carotene. The dark green color of Spirulina is attributed to a combination of pigments, including carotenoids (orange), phycocyanin (blue), and chlorophyll (green). Spirulina sp. exclusively contains chlorophyll a, with levels ranging from 0.8% to 1.5% of its dry weight. Additionally, freeze-dried Spirulina sp. boasts a notable xanthophyll content, measuring at 6.9 g.kg-1. Other prominent carotenoids include β-carotene (28%), mycoxanthophyll (37%), and zeaxanthin (17%). Owing to its pigment composition, Spirulina sp. is employed for ornamental fish pigmentation, particularly in Goldfish and Black molly, as a feed additive. If Gold fish and Black Molly fails to achieve the desired coloration level, it can result in a substantial decrease in market demand and the value of the fish. Despite the availability of fish feeds enriched with carotenoids in the market, they tend to be costly. Therefore, our study aimed to explore the impact of Spirulina on both the pigmentation and growth of Goldfish and Black Molly
