Dr. Tamás Müller specializes in the technology development of induced spawning, larvae, and juvenile rearing under controlled conditions for economically important and endangered fish species. Currently, his primary focus is on a newly developed fish propagation method, exploring its applications in both basic knowledge and practical use. This innovative method seamlessly combines the simplicity of induced spawning with the advantages of conventional in vitro fertilization. The insemination technique holds potential for breeding programs, intra- and interspecific hybridization, and is a viable method for utilizing manipulated/cryopreserved sperm.
