Report from a business trip, Spain, Bondarenko

In the period from October 30 to November 3, I visited prof. Luz Perez, prof. Juan Asturiano and their Group of Aquaculture and Biodiversity, from the Polytechnic University of Valencia (UPV), Spain. During my stay, I gave lectures for master's students regarding fish spermatozoa, mostly focused on freshwater species. The study program of UPV is focused on marine fishes, so talks highlight mechanisms of spermatozoa motility in freshwater species supplemented course. Also, we discussed some of our previous results with prof. Luz Perez and possibilities for future collaborations. The travel was financially supported by the Erasmus+ program.
