In the frame of the "AQUAGAMETE COST" Action was held in our faculty the 4^th AQUAGAMETE Training School. This Training School is aimed towards young researchers (Ph.D. students, young post-docs and MSc. students) as well as representatives from industry. The course is focused on Optical Microscopy Techniques and Image Analysis Facilities assisted by Computer used in Reproductive Biology, potentially applicable to aquatic gametes and early embryos.

The Training School aims to highlight the most recent developments in each topic, thanks to 12 invited lecturers/trainers so as to promote a strong interaction between the 20 trainees working on different aspects of Reproductive Biology of Aquatic Gametes and experienced trainers as specialists in the use, improvement and development involved in the above-mentioned Optical and Computer applications.

The Training Course was taking place from 16^th to 20^th March 2015 at the Faculty of Fisheries and Protection of Waters USB, in Vodnany, Czech Republic facilities and its organization mostly relies on the staff of the Laboratory of Reproductive Physiology belonging to the Research Institute of Fish Culture and Hydrobiology, with the assistance of several members of the Institute of Complex Systems.
