Understanding connectivity among exploited populations is critical to their sustainable management and long-term viability. In the marine environment, estimates of connectivity often rely on the use of genetic markers, as dispersal primarily occurs during a planktonic larval phase which is difficult to track using direct methods. In this thesis, we investigated the population genetic structure of the most valuable commercially harvested species on the west coast of the United States, the Dungeness crab (Cancer magister). Genetic connectivity of Dungeness crab in the California Current System (CCS) was compared to genetic connectivity among Dungeness crab inhabiting a partially enclosed water body, Puget Sound. Findings highlight the need for future research to investigate demographic processes that influence gene flow (i.e. dispersal trajectory).
