A genetic analysis by the National Institute of Fisheries Science has determined that blue crabs across all Korean waters belong to a single population, likely diverging from a common ancestor recently. Conducted from December last year to last month, the study found minimal genetic differences among blue crabs from the west, south, and east coasts. Blue crabs are a significant fishing resource in Korea, especially in the West Sea, with a notable increase in catches in the East Sea over the past decade. These findings are essential for the effective management and sustainability of blue crab populations in Korea.
