Fishery mortality on returning individuals was simulated by the removal of a proportion of each sea age class (1SW or MSW, base proportion of 15%) from the population at the end of summer step, that is after the observation of number of returns and proportions of MSW.
The reproduction events were simulated according to relevant S. salar literature (Fleming 1996). The mating system allowed mature male parr to fertilize a fraction of the eggs. It selected anadromous males following size dominance while allowing satellite males to fertilize a significant fraction of the eggs. The number of egg per female was size dependent. Egg-to-emergence survival was water temperature, river flow and density dependent.
