Abstract

The Marine Life Management Act, closure of several near-shore demersal fisheries and the establishment of no-take marine reserves are recent embodiments of long standing disagreements between California’s fishing industries and California regulatory agencies (CDFG 2002). Fundamental arguments are over data on population trends and local versus regional population recruitment patterns. Species of concern in the latest closure included the “rockfish-cabezon-greenling” complex (Musick et al. 2000). This project deals with one of the target species of the closures. We propose to estimate population genetic structure in a species central to the commercial and recreational over-fishing debate: the cabezon (Scorpaenichthys marmoratus).
