When are estimates of spawning stock biomass for small pelagic fishes improved by taking spatial structure into account?

Abstract:

Consideration should be taken of including spatial structure in the models on which stock assessments are based. Abstract A simulation-estimation approach is used to evaluate the efficacy of stock assessment methods that incorporate various levels of spatial complexity. The evaluated methods estimate historical and future biomass for a situation that roughly mimics Pacific herring Clupea pallasii at Haida Gwaii, British Columbia, Canada. The baseline operating model theorizes ten areas arrang...
