Recently, there has been an increase in cases of using invasive alien species that have entered the country as food ingredients. For example, Busan green crab (sawtooth crab) has established itself as a high-end delicacy, and largemouth bass and bluegill are being transformed into spicy stew and fish cakes. In addition, plant invasive species such as prickly lettuce, Japanese knotweed, and devil's claw are being used as leafy vegetables or side dishes. YouTubers are creating content by catching invasive alien species themselves and cooking them, raising environmental awareness. Some local governments are promoting purchasing projects to increase fishermen's income and control the population at the same time.
