Predicted probability of capturing one or more Pacific mackerel (Scomber japonicus) larvae at sample 
locations based on the logistic generalized additive model at the median values of sampling day and 
commercial-passenger-fishing-vessel index (i.e., controlled for stock size and sample date). Area enclosed 
by the black line indicates the core area, which was sampled in all years of the survey. The black line 
indicates California Cooperative Oceanic Fisheries Investigations line 95 separating northern Mexican 
waters from southern Mexican waters near Punta Eugenia. Black “thermometers” 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.
