Capelin and sandeel are zooplanktorous fishes that in other areas are important for the transfer of energy from zooplankton to the highest trophic levels. Due to their life-history, short-lived and highly fecund, their population dynamics are heavily impacted by changes in the oceanographic conditions. Spatial and interannual changes in their growth and condition (e.g. lipid content) are likewise dictated by prey availability and oceanographic conditions, especially temperature. Consequently, their value as prey for top predators varies spatially and temporally. This project investigates the ecology of these species in West Greenland waters and the variability in the population dynamics and nutritional value of these fishes. Fishing for sandeel and capelin is done during three field campains in May, August and September 2013.
