This study aimed to investigate the impact of climatic factors on the offshore fishery catches in Korea over the past three decades and their effect on the fishery product supply. It focused on seven major fish species popular in Korean side dishes. The study data were entirely obtained from the official statistics of Korea. Data analyses, such as trend analysis and regression analysis, were done using SPSS software package. Over the last 30 years (1981 to 2010), cold-water fish species, such as Alaska/walleye pollock, have almost disappeared; however, catches of warm-water species, such as anchovy and squid, have greatly increased (p<0.05). During the study period, the sea surface temperature (SST) and air temperature of Korea significantly increased (p<0.05). The per capita annual consumption of fishery products in 2010 was much higher than that of 1981; however, the self-sufficiency ratio declined remarkably. Changes in catches due to SST changes strongly affected consumer prices of fish species such as Alaska/walleye pollock, while consumer price index (CPI) of Pacific saury was representative of the overall CPI for living. The results indicate that the fish species caught have changed during the long period because of the rise of air temperature and SST. These results warn that fish catches will change more due to ocean warming around the Korean peninsula. If the Korean fishery product consumption steadily increases, it would lead to a rise in its fishery prices (fishflation).
