Gangneung, South Korea – A decline in Pacific flying squid populations is forcing South Korean fishing communities to adapt, with a significant drop in the number of smaller vessels and a corresponding rise in distant-water fishing operations, according to government data released February 20.
The Ministry of Oceans and Fisheries’ fisheries statistics portal shows that in North Gyeongsang Province, the number of fishing vessels over 10 tons decreased by 15.7% – from 438 in 2020 to 369 in 2024. This decline mirrors a broader trend of dwindling squid catches, a mainstay for many local fishermen.
Catches of Pacific flying squid in the region plummeted from 20,653 tons in 2020 to just 2,793 tons in 2023, an 86% reduction in four years. Analysts attribute this drop to rising sea temperatures, which are shifting the squid’s spawning and feeding grounds northward, towards waters off northern Gangwon Province and near North Korea.
Concerns also center on the activities of large-scale Chinese fishing fleets operating in North Korean waters. In 2020, Global Fishing Watch reported that squid populations in South Korean and Japanese waters had fallen by approximately 80% since 2003, linking the decline to illegal fishing by foreign vessels. The organization estimated that over 900 large Chinese vessels harvested more than 160,000 tons of Pacific flying squid between 2017 and 2018, valued at roughly $500 million – a volume comparable to the combined annual catch of South Korea and Japan.
As nearshore squid stocks diminish, South Korean fishing companies are increasingly turning to distant-water fishing. In Busan, the number of vessels exceeding 200 tons rose 18%, from 273 in 2020 to 321 in 2024, although the number of mid-sized vessels decreased. Despite this shift, the overall number of registered fishing vessels in Busan remained relatively stable, at 3,339 in 2024 compared to 3,333 four years prior.
Government data indicate a substantial increase in distant-water squid production, nearly doubling from 31,500 tons in 2023 to 63,200 tons in 2024. This expansion into more remote fishing grounds suggests a strategic response to the depletion of local squid populations.
Recent amendments to the Coastal and Inshore Fisheries Structural Improvement Act may offer a pathway for fishing households facing financial hardship, according to industry groups. However, the long-term impact of these changes remains to be seen.
Jumunjin Port, a significant fishing port on the east coast, has historically been a key location for squid fishing, with over 350 fishing boats operating in the area. The port is situated where warm and cold currents meet, creating a rich environment for various fish species, including squid, according to VisitKorea.
