cold stock, California Current population
According to the latest stock assessment report (Hill et al., 2011) sardine off the West Coast of North America is thought to consist of three subpopulations or stocks. A northern (“cold”) subpopulation (northern Baja California to Alaska) covered within this profile, a southern subpopulation (outer coastal Baja California to southern California), and a Gulf of California subpopulation have been distinguished by population studies, although some uncertainty remains.
