Trophic interactions between fish in their first year of life (i.e. the age-0 group) as predators and zooplankton as their prey have been a main topic of limnological investigations during the last two decades. Consequently, the idea was born to organise a workshop where specialists from both the fish and zooplankton sides of limnology should discuss their research results and summarise the state if the art. A suitable frame for this workshop was found within the Plankton Ecology Group (PEG). The PEG was held in Dresden with 42 participants from 12 countries. Twelve papers presented in this issue span the whole range of topics discussed during the 3 days of the meeting.
