Figure 1 
Average monthly distribution of the potential habitat of adult Pacific sardine (Sardinops 
sagax) in the California Current Ecosystem (Zwolinski et ah, 2011) during 2008. The 
model accurately predicts the habitat of sardine, irrespective of their spawning condition. 
“Optimal” habitat should include 80% of the sardine, “good” plus “optimal” habitat should 
include 90%; “bad” plus “good” plus “optimal” habitat should include 99%; and “unsuitable” 
habitat should include <1% of the total sardine. In the spring, the potential sardine habitat 
is located offshore of southern California. In the summer, the potential sardine habitat is 
compressed along the coasts of Oregon, Washington, and Vancouver Island.
