Training of Marta Blanes and Leonor Ferrão

 Between October 24th and November 26th, this year we had the pleasure of hosting Marta Blanes and Leonor Ferrão of the Group of Aquaculture and Biodiversity under the leadership of Prof. Juan F. Asturiano at the Polytechnical University of Valencia in Spain. Marta and Leonor were trained by Zoran in various techniques including isolation of germline stem cells (GSCs), treatment of embryos with  morpholinos to induce sterility as well as transplantation of GSCs into suitable recipents. Their work was part of the EELGONIA project funded by the Spanish Ministry of Science and Innovation. During their stay, Marta and Leonor have isolated GSCs from cryopreserved gonads of the European eel and transplanted them under Zoran's supervision into sterilized zebrafish and common carp larvae. The recipient larvae are currently grown in our facilities and we cannot wait to see what will happen to the transplanted cells.

Aquaculture Europe 2021

 Zoran and Ákos attended the Aquaculture Europe 2021 meeting that was held on October 4-7 in Funchal, the capital city of the beautiful island of Madeira in Portugal. The meeting was organized by the European Aquaculture Society and attended by more than 1400 participants. The conference was of special interest for us because of the opportunity to meet our friends Juan F. Asturian of the Polytechnical University of Valencia (Spain) and Elsa Cabrita from CCMAR and University of Algarve (Portugal) who was also co-chairing the session on Reproduction. The conference was very well-organized with high-quality sessions and a large trade show. Regarding the cons, the e-poster session was virtually invisible and completely insignificant. A classical poster session with poster boards would have been much nicer. Nevertheless, we had a good time and will definitely come to EAS next year.

The posters presented were:

Á. Horváth, B. Pataki, G. Mészáros, Z. Marinović, N. Kitanović, B. Urbányi: Does sperm concentration matter in carp sperm cryopreservation?

Z. Marinović, J. Lujić, S. Sušnik Bajec, I. Djurdjevič, A. Snoj, B. Urbányi and Á. Horváth: Triploid rainbow trout Oncorhynchus mykiss as a recipient of brown trout germline stem cells.

Bernadett Pataki, Béla Urbányi, Tímea Kollár, Ákos Horváth: Inheritance of sperm cryoresistance in common carp (Cyprinus carpio)
