Overview

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.

2020-2024; NKFI_K_135824, project leader

Fish propagation by using sperm insemination into ovarian lobes

Our newly developed fish propagation method, which is based on sperm insemination into the ovary using a catheter in externally fertilized fish species, enables targeted breeding efforts that were previously limited to the induced spawning method. Insemination can also be carried out using qualified or manipulated semen.

Optimization and practical applications of new fish propagationmethods for future of fish culture

The Hungarian and Turkish partners work together on industrial application of a novel reproduction method for seabass and pikeperch based on the scientific results (insemination) of MATE researchers. The method provides the possibility to produce higher amount of fertilized eggs per unit area.
