“…Spirulina contains vital compounds, including protein (50-70% on dry mass basis) with all essential amino acids (Farag et al 2016), carotenoids, chlorophyll, pigments, essential fatty acids (alpha-linolenic, gamma-linolenic, and linoleic acid (Mendes et al 2003, Peiretti andGiorgia 2011), photosynthetic pigments (Bermejo et al 2008), vitamins (thiamine, nicotinamide, riboflavin, folic acid, pyridoxine, vitamins A, D, and E) (Hosseini et al 2013) and minerals (such as Ca, K, Cr, Cu, Mn, Fe, P, Mg, Na, Zn, and Se) (Babadzhanov et al 2004), making Spirulina an efficient feed supplement (Yousefi et al 2019). Nevertheless, the potential remediation effects of Spirulina against toxicity of phytohormones such as GA 3 have not been investigated, especially in fish of high economic importance (Sayed et al 2020).…”
