Table S1. Clupea pallasii. Estimates of age-specific and total recruitment, abundance, and death (by numbers and biomass) in

Prince William Sound using the best model. Total pre- and post-fishery estimates are highlighted in yellow; estimates before the

spring fishery are highlighted in green. Totals for these values are different from those in Fig. 4 because this table includes all

Age 3+ fish, whereas Fig. 4 includes only spawning (mature) fish (immature Age 3 fish cannot spawn)
