On 3 and 4 April 2025 we participated in the fifth Workshop within the bilateral project BYCZ-SPF00088 Fish Welfare Education - Knowledge Transfer and Innovation in Fisheries Science, which is supported by the Small Project Fund of the Interreg Bavaria-Czech Republic Programme. The programme of the workshop included an introductory theoretical lecture on the influence of water temperature and light regime on fish recruitment and the influence of water quality on fish reproduction in general. In the second part of the workshop, a practical demonstration of different methods of artificial fish spawning and of the grayling was given. Particular attention was paid to the assessment of male sperm quality and the possibility of increasing sperm motility by using fertilization solutions.
