The 'Fresh Blood for Fresh Water' is a community meeting of early-career limnologists, representing not just new incomers to the field, but also those who still (or forever) feel themselves “fresh blood”. The conference aims to provide a friendly atmosphere to meet, to present the new results and exchange ideas with other young researchers. In 2019, young researchers of the MTA Centre for Ecological Research welcome the conference in Tihany, Hungary, at a beautiful venue. The program will include various sessions for talks and posters, four plenary talks by early-career group leaders with outstanding achievements in their fields and workshops covering both theory and practice given by senior and advanced junior scientists. Several social events will complete the scientific program. For details, please check our website: http://fbfw2019.okologia.mta.hu/
