The article highlights the potential significant impact of the Russian invasion of Ukraine on the Korean fishery industry and calls for the development of countermeasures. With the conflict showing no signs of ending soon, it is causing supply and demand issues and the effects of economic sanctions to surface. The war is disrupting industries such as deep-sea and offshore fishing, aquaculture, and coastal fisheries, affecting areas like pollack imports and Norwegian salmon. Rising oil prices, which account for over 40% of offshore fishing costs, are also expected to harm the industry. The article urges the implementation of short-term and long-term measures to mitigate the damage to fishermen, such as identifying alternative supply lines and preparing support measures for farmed fish in response to increased compound feed prices.
