Field work in Slovenia

Five of us were in Slovenia for sperm cryopreservation work from 11-04-2016 to 15-04-2016.

our team: Gergő, Ákos, Kinga, Eszti and Zoli

Our team was complemented with the company of a Portuguese collegue, Carina Caldeira, who is an IMPRESS student at the company Proiser. She is currently on a Short-term Scientific Mission of the COST Action FA-1205 AQUAGAMETE carrying out sperm analysis of various fish and shellfish species.

Sperm samples from grayling (Thymallus thymallus) individuals were taken in the area of the Angling Association of Tolmin, with the help of Dušan Jesenšek and his team.

 We also worked with the grayling of the fish farm:

Carina was working on the improvement of the PROISER CASA system, Eszti was doing vitrification experiments, and the rest of the team did cryopreservatin trials.

fertilization tests were also carried out with cryopreserved and vitrified sperm samples
