Worldwide tilapia production is rapidly growing and becoming increasingly reliant on the provision of cost-effective sustainable formulated feeds. In the paper, the authors assessed the capacity for various inclusion rates of the feed additive Novacq™ to improve growth performance in extruded diets containing 10% fishmeal as well as the growth response at 5% and 0% fishmeal, with or without the addition of 10% Novacq™ in extruded diets for GIFT tilapia fingerlings.
