Answer:
Rockfish larvae are pelagic, there is genetic evidence for limited dispersal within Puget Sound for the quillback and copper (S. caurinus) rockfish (Seeb 1998) as well as for differentiation from coastal populations of brown rockfish (S. auriculatus) (Buonaccorsi et al. 2002). This degree of population structure is consistent with other genetic and otolith studies from coastal Pacific rockfish populations
