South Jeolla Province conducted a preliminary inspection of the oyster operation and cage farm in Dolsan, Yeosu due to low-water temperature cages in winter. A low-water temperature advisory was issued in several areas in December last year, affecting around 5.6% of farmed fish in the region. Concerns about damage to vulnerable fish species, such as sea bream and filefish, have led Jeonnam Province to plan to spend 5 billion won to expand its oyster production base.
