Until recently, the thick ice cover and the remoteness of the central Arctic Ocean precluded fish and zooplankton sampling at a large scale. Recent scientific missions partly filled these data gaps and brought new insights into distribution and activity patterns of zooplankton and fish. However, it is still unclear how the combined effect of longer ice-free seasons, changing light field, warmer temperatures, and increased competition and predation from boreal species will impact key ecological species. The effects of ocean warming coupled with a changing predator community on zooplankton and fish may trigger behavioural and physiological responses that will alter productivity and disrupt the energy flow in Arctic food webs. This topical session seeks to advance our understanding of present and future responses of both fish and zooplankton to climate change at high latitudes. We encourage contributions that broadly focus on the ecology of fish and zooplankton species as well as other key ecosystem components.
