Pacific ocean perch is assessed and managed as a single unit in the in the Bering Sea/Aleutian Islands (BSAI), but the stock structure of this species is still not fully understood (Spies and Spencer, 2012; Kamin et al., 2013; Spencer and Ianelli, 2014). Some recent studies indicate a finer scale stock structure exists within the Gulf of Alaska and BSAI (e.g., Palof et al., 2011; Kamin et al., 2013). Research is underway to clarify genetic structure of this species and its relationship to population dynamics (Spencer and Ianelli, 2014).
