The University of Debrecen in Hungary is working on incorporating the perch, a native premium fish, into intensive fish production. The project aims to develop production technology, improve housing and feeding conditions, and explore the use of wastewater. The university is also developing insect protein-based feeds to replace fishmeal and recycling effluent for the production of planktonic food organisms and aquaponic plant production. A new floating cage system has been developed to increase production without overusing natural resources.
