Abstract
The variations of catch of anchovy and saury due to oceanic climate change in the Korean Seas were studied. This study area was $31^{\circ}{\sim}38^{\circ}$ N and $124^{\circ}{\sim}132^{\circ}$ E. And data (seawater temperature, salinity, dissolved oxygen) is used from NFRDI (National Fisheries Research and Development Institute) and SST (Sea Surface temperature) obtained to satellite images (NOAA/AVHRR) during 2000 to 2009. The spatial characteristics are analyzed by GIS (Geographic Information System). The results showed that the average of seawater temperature in the depth of 20m increased $1.45^{\circ}C$ in the South Sea and $0.83^{\circ}C$ in the East Sea, respectively. The maximal catch of anchovy was highest in summer (July~September) and winter (December~March), respectively, in compared with spring (April~June). Catch of anchovy has increased since 2000. The maximal catch of saury was highest in spring (May~June), in compared with spring (August~September). The increment of seawater temperature contributed to increase the catch of anchovy, but catch of saury was decrease in the same times.
