Predicted probability of capturing one or more Pacific mackerel (Scomber japonicus) larvae at sample 
locations based on the logistic generalized additive model for California Cooperative Oceanic Fisheries 
Investigations (CalCOFI) oblique-tow samples, 1951-2008. Only sites with a complete set of predictors 
are plotted. Area enclosed by the black line indicates the core area, which was sampled in all years 
of the survey. The black line indicates CalCOFI line 95 separating northern Mexican waters from 
southern Mexican waters near Punta Eugenia. Black “thermometer'’ bars indicate mean relative mean 
probability of capture in the core area (left bar), northern Mexican waters (middle bar), and southern 
Mexican waters (right bar). Where samples occurred so closely spaced that some overlap occurred, 
samples with the greatest predicted probability of capture are plotted on top.
