Logbook data of the 2006-2008 Taiwanese Pacific saury fishery, coupled with MODIS satellite-derived sea surface temperature (SST) data, were used to determine Pacific saury's SST preferences and predict their potential habitats monthly. Results indicated that the SST preferences ranged from 12 to 18.5 degrees C, with significant monthly variability. Possible changes in potential saury habitats were estimated under four scenarios: recent years (2006-2008) and with 1, 2, and 4 degrees C increases in SST because of climate change. Results revealed an obvious poleward shift of potential saury habitats under the influence of increases in SSTs. The southernmost boundary of potential saury habitat in recent years, located at 40.24 degrees N, shifted to 46.15 degrees N under the scenario of a 4 degrees C increase in SSTs. These results improve our understanding of the variability in the spatial distribution of saury habitats and could form the basis for future fishery management and fishing forecasts.
