SIU researchers seek to use invasive copi as baby food for farm-raised yellow perch

Caring for a human baby is hard. Two researchers at Southern Illinois University Carbondale will tell you raising “infant” fish may be even more challenging.

Karolina Kwasek and Michal Wojno are trying to find better ways to hatch and successfully raise yellow perch to the juvenile stage in aquaculture. A married couple with a baby of their own, they use research methods that combine low-tech hatchery equipment, easily copied by professional fish farmers, with creating a new feed that uses the invasive species copi as a protein source.

The research will last through 2023. Success would mean greatly increasing yellow perch’s survival rates at indoor hatcheries, leading to business expansion for more aquacultural ventures and better prices for consumers.
