The probability that a fish matures at a certain age and length (the so‐called probabilistic maturation reaction norm, PMRN ) was analysed for a European whitefish Coregonus lavaretus species complex population living in the Austrian pre‐alpine Lake Irrsee. Fish length was found to be the only relevant determinant of maturation probability, and females matured at slightly smaller sizes than males.
