The relative importance of subpopulation connectivity and the age distribution of mortality in exploited marine fish populations
Description: Exploited marine fish populations are known to exhibit complex spatial dynamics and display age-structured processes, yet many models of these populations do not account for within-population variability in age in conjunction with the spatial distribution of individuals within a stock management area. Using a hybrid model together with its parameterization, scientists show that assumptions about the age distribution of mortality affect predictions of spawning population attributes, namely abundance and the proportion of the stock that is mature.
