Screening Microalgae Strains for Fish Feed of Juvenile Nile Tilapia (oreochromis Niloticus) and Their Zootechnical Performance

Fishmeal, the main protein source in fish feed, may become unsustainable due to economic and environmental issues in the fishing industry. In this work, we developed fish feed for juvenile Nile tilapia (Oreochromis niloticus) enriched with microalgal biomass as an alternative protein source. Considering the cyanobacterium Arthrospira maxima and the green algae Chlorella sorokiniana and Neochloris oleoabundans, A. maxima biomass was more suitable for the development of fish feed, based on its protein content ( 70
