Scenario 1—Demographics of juvenile population.

Statistical measures of juvenile (parr+smolt) densities per m2 at the beginning of the resting season. Density data are broken down per life phases and age groups. The tables report the averages and standard deviations over 100 years, averaged over 10 independent runs of the model. The overall minimum and maximum values over the 100 years and 10 independent runs are also reported. The results are compared with statistical measures of population surveys carried out in the Os river in the period 1991–2010 (Rådgivende Biologer AS, 2012).Scenario 1—Demographics of juvenile population.
