Northern krill (Meganyctiphanes norvegica) is an important species in the North Atlantic and the Mediterranean Sea, but very little life-history information is available under controlled (laboratory) conditions. Here, we use the DEBkiss model to piece together the available data into a quantitative energy budget. We use this model to analyse larval growth curves, and to reconstruct the feeding history for field populations from their (reconstructed) multi-year growth patterns. The resulting model parameters are also used to provide estimates for respiration, feeding and reproduction rates that are consistent with measured values. Many uncertainties remain, but this analysis demonstrates how simple and generic energy-budget models have the potential to integrate observations on different traits, to interpret growth as a function of food and temperature, and to compare different species in a meaningful manner.
