Popis: Abstract In this study, the impact of adding 10% or 20% torula yeast (PB TY10 and PB TY20) to a fishmeal‐free diet on digestibility and growth of juvenile rainbow trout was assessed. The yeast diets were compared with a plant‐only diet (PB) and a diet containing 20% fishmeal (FM). The apparent digestibility of dry matter, protein, energy, and ash of yeast in trout (~120 g) were 78.6%, 93.8%, 84.8%, and 48.7%, respectively. All PB diets had higher protein digestibility and PB TY20 had higher ash digestibility than the FM diet. To assess growth, trout (~44 g) were divided into triplicate tanks (30 per tank) and fed one of the four experimental diets for 12 weeks. The PB diet resulted in lower growth and daily feed intake (p
