Overview
Tamás Müller is a professor at the Department of Freshwater Fish Ecology of the Institute of Aquaculture and Environmental Safety.
His research focuses on technology development of induced fish reproduction, larvae and juvenile rearing under controlled condition. His expertise lies in the artificial induction of sexual maturation and propagation of fish. In addition, his work concentrated on the ex-situ conservation biology of threatened and endangered fish species.

NKFI Alap (NKFI_K_ 135824): Fish propagation by using sperm insemination into ovarian lobes (2020-2024)
There are difficulties to propagate several economically important or endangered fish species by using tradional method (based on gamete collection). In that case induced spawning/tank spawning, pen spawning the only way to reproduce them. Our newly developed method, which based on sperm insemination into ovarian by using catheter, allows targeted breeding work, which has so far been limited to induced spawning method. As a result, genetic diversity can be increased - in case of spawning fish, targeted crossings can be performed, insemination can be carried out with qualified or manipulated semen. A further result of the work is that we better understand the physiological features of the infertilized fish and the process of fertilization of the fish (possibly including the initial or complete process of embryogenesis), which provides answer for important evolutionary development. https://akvakultura.uni-mate.hu/en/projektek
NKFI (2020-1.2.4-TÉT-IPARI-2021-00011): Optimization and practical applications of new fish propagation methods for future of fish culture (2020-2024)
The new propagation methods developed by MATE researchers enable large-scale classical fish propagation procedures (e.g., controlled spawning, manipulated sperm) that were previously difficult or infeasible in induced spawning. The project partners guarantee the success of applying this new propagation method to economically important freshwater fish (pikeperch, African catfish) and marine fish (sea bass). This effort is supported by leading agricultural-focused universities (MATE and Akdeniz University), the research institute (MFRPTI), one of the most important fish processing and production companies in Hungary (V95 Ltd.), and the most significant aquaculture company in the Mediterranean (Kilic Holding). https://palyazatok.uni-mate.hu/web/mate-p%C3%A1ly%C3%A1zatok/2020-1.2.4-t%C3%A9t-ipari-2021-00011
