Promoting the use of microalgae in aquafeeds

NEWS

A study led by the Nord University (Bodø, Norway) assessed the role of pre-extrusion and supplemental additives as novel approaches to improve the utilization of microalgae Nannochloropsis oceanica in plant-based feeds for Atlantic salmon.

The present study showed that the incorporation of 10% pre-extruded microalgae (Nannochloropsis oceanica) in plant-based feeds although reducing lipid digestibility, had no detrimental effects on growth, feed utilization and body proximate composition in Atlantic salmon. As part of its continuous effort to promote the use of microalgae in aquaculture feeds, SPAROS has formulated and manufactured the experimental diets used in this trial. This study was funded by the Research Council of Norway (Project

No. 260190, Alger-4laks) and is part by the COFASP ERA-NET project

MARINALGAE4aqua.
