Description:
Fisheries science often uses population models that assume no external recruitment, but nearshore marine populations harvested on small scales of 0.775 (equivalent to 52.85% self-recruitment under present conditions). Elasticity analysis of demographic parameters indicated that future abundance can most effectively be influenced by increasing survival of mid-sized clams (?80?120 mm) if the population is self-sustaining, and by increasing survival of juvenile clams (?40?70 mm) if the population is non-self-sustaining (as for an open population). Our results illustrate that management priorities can vary depending on the amount of self-recruitment in a local population. # doi:10.1890/13-1201.1
