Nile tilapia (Oreochromis niloticus) show high digestibility of lipid and fatty acids from marineSchizochytriumsp. and of protein and essential amino acids from freshwaterSpirulinasp. feed ingredients

We determined apparent digestibility coefficients (ADCs) of macronutrients, amino acids and fatty acids for freshwater (Spirulina, SPI; Chlorella, CHL) and marine (Schizochytrium, SCI) microalgal ingredients in Nile tilapia via four diets: reference (Ref containing fish and plant feedstuffs) and SPI, CHL and SCI (Ref/dried algal cells at 7:3). ADCs of crude protein were significantly higher in SPI than in CHL, comparing well with literature...
