Overview

Dr. Balázs Kovács serves as the Deputy Head of the Department of Molecular Ecology and leads the Fish Molecular Genetics Research Group. His research focuses on fish molecular genetics and biology, with a particular emphasis on investigating the genetic and genomic background of natural (protected, endangered, or invasive) and cultured fish stocks and populations. He has experiences in marker development, breeding and selection programs, genomic or gene expression analysis of fish species, transgenic model animal development, or development of toxicological test systems.  His current objective is to study the genomics of fish sex determination and apply this knowledge to enhance the sustainable production of economically important fish species.

Projects

Intelligent Fish feeding through Integration of ENabling technologies and Circular principle
The iFishIENCi EU project enhances fish farming with innovations, monitoring systems, smart feeding, and health tracking. Collaborators refine systems, optimize breeding, and improve feeding efficiency in key commercial fish species (African catfish, tilapia, and trout). It also explores waste valorization, aiming for zero waste and value creation.
