Abstract

Purpose: This study investigated the relationship between climate factors and the catches in Koreanoffshore fisheries in recent three decades (1981 to 2010). Method: This study focused on seven types of fish species preferred in Korean cuisine. In the study, 10-year moving averages were used so that long-term trends could be easily identified. Results: Both air temperature and sea surface temperature (SST) on the coast of Korea rose in the period (p < 0.05). The rise in SST was significantly correlated with the rise in air temperature (p < 0.05), but not with precipitation. In the 2010s compared to in the 1981, catches of anchovy and squid greatly increased (p < 0.05), while catches of Alaska / walleye pollock has been almost extinct over the past 30 years. As such, cold-water fish species decreased or disappeared, and their fishing ground was replaced by warm-water fish species. Conclusions: These findings indicate that fish species caught in offshore fisheries of Korea have changed due to climate change, especially warming. This suggests that the warming of the Korean Peninsula may have a significant impact on the supply of fishery products and food security to Koreans in the near future.

연구목적: 본 연구는 지난 30년(1981~2010년) 동안 우리나라 기후 요인과 근해 어업에서 어획량의 관계를 조사 분석하였다. 연구방법: 본 연구에서 어획량은 한국인 식탁에서 선호되는 7가지 어종을 대상으로 하였다. 본 연구에서는 장기적 추세를 쉽게 파악할 수 있도록 10년 이동평균을 사용하였다. 연구결과: 동 기간 동안 우리나라 연안의 기온과 표층수온(SST)은 모두 상승하였다(p < 0.05). SST의 상승은 기온의 상승과 유의한 상관관계가 있었지만(p < 0.05), 강수량과는 상관관계가 없었다. 2010년에는 1981년에 비해 멸치와 오징어 어획량이 크게 증가한 반면(p < 0.05), 명태는 거의 멸종되어 어획량이 거의 없었다. 이처럼 냉수 어종은 감소하거나 사라지고 어장은 온수 어종으로 대체되었다. 결론: 이러한 결과는 우리나라 근해 어업에서 어획되는 어종이 기후변화, 특히 온난화로 인해 변화했음을 나타낸다. 이는 한반도의 온난화가 가까운 장래에 한국인의 수산물 공급과 식량 안보에 중대한 영향을 미칠 수 있음을 시사한다.
