Abstract

Catch data (3,416 MT during 1984 and 56,350 MT during 1994) indicate that abundance of Pacific sardine (Savdinops sagux) along the west coast of Baja California has increased dramatically. Increases were closely re- lated to abundant year classes in 1984, 1989, and 1993. The abundant year classes in 1984 and 1993 followed El Niilo events. Seasonal patterns in catches lead us to hy- pothesize that sardine migrate seasonally between Magdalena Bay and Ensenada, moving northward dur- ing the summer and fall and southward during winter and spring. The period of highest abundance after 1989 was associated with a northern shift in the distribution of sardme and increased catches in Ensenada. Peak catches occurred in a bimodal pattern at 17" and 20C near Ensenada in the north, at 17" and 21" near Cedros Island, and at 19" and 24" near Magdalena Bay in the south. This pattern suggests the possibility of three stocks along the west coast of Baja California
