Feed made from food wastewater spurs hopes of cheaper fish

Fish on the dinner table could one day be produced more sustainably and possibly more affordably as local scientists have found a way to create fish food from food processing wastewater. Professor Stefan Wuertz, lead investigator of the study published in the journal Scientific Reports said that the idea is to find a sustainable source of protein in the feed, so that the aquaculture industry can grow. His team, from the Singapore Centre for Environmental Life Sciences Engineering (SCELSE) and Temasek Polytechnic’s Aquaculture Innovation Centre (AIC), created fish food pellets where half the fishmeal is replaced by a microbial protein.
