"The Gulf of California supports an important fishery of small pelagic fishes. However, these species have undergone variations in both their geographic distribution and abundance over time. A GIS-based approach was used to investigate the association between weekly remote-sensed sea surface chlorophyll-a concentrations (Chl), sea surface temperature (SST) images, derived SST and Chl gradient maps, and daily fisheries catch data for Pacific sardine (Sardinops sagax caeruleus), thread herring (Opisthonema libertate), northern anchovy (Engraulis mordax), and Pacific mackerel (Scomber japonicus) from 2002–07. SST did not have a significant affect on most species, except for northern anchovy (r2 = 0.71), while Chl was significant for Pacific sardine (r2 = 0.94), thread herring (r2 = 0.90), and Pacific mackerel (r2 = 0.96). However, the SST gradient was more strongly associated with the abundance of the species studied.The Chl gradients showed similar values in relation to SST gradients with the exception of northern anchovy (r2 = 0.43)."
