Extreme climate events, overexploitation and in general human activities can lead to a strong elevation of mortality, particularly for young and sensitive life stages. Such mass mortality events are predicted to occur more frequently. In our study published in Global Change Biology (Langangen & Durant, 2024), we recorded the chance of collapse of fish populations confronted to various levels and frequency of mass mortality events.

Mass mortality events are on the rise globally. However, we have a limited understanding of the population consequences of such events that particularly affect the early life of fish. To increase our understanding of the population-level effects of mass mortality in early life, we constructed population models for 40 fish species and ran scenarios on mass mortality for these species. Our approach allows for predictions of potential effects of mass mortality in a range of fish.
