Effect of yeast-fermentation and extrusion of canola meal on digestibility and growth performance of rainbow trout and Nile tilapia

Researcher: Murray Drew, Chuyuan Zhang, University of Saskatchewan, Saskatoon SK

Project Code: CUP SCDC 2014.4 Drew

Final Report: April 2017

Summary: Canola meal (CM), a by-product of canola crushing, is the primary high-protein ingredient in Western Canada that is used as a protein supplement in feed rations for livestock, and being evaluated as an ingredient in fish diets. Researchers at the University of Saskatchewan conducted a two-year project to examine the effects of feeding enzyme pre-treated and yeast-fermented canola meal (FMC) on the nutrient digestibility and growth performance of Nile tilapia and rainbow trout. Overall, the study results showed that FMC can be used in diets for herbivorous and omnivorous fish such as Nile tilapia without negative effects on growth of fish. However, there may be concerns using FMC as fishmeal replacer in carnivorous fish diets, such as rainbow trout.
