All crabs from the East and West Seas in Korea are from a single flock

As a result of a recent analysis of the genetic structure of each population of blue crabs living in all waters of Korea, it was found that they are all the same single population. The National Institute of Fisheries Science announced on July 22 the results of a study on the genetic structure of blue crabs living in domestic waters conducted from December of last year to last month and made this statement. Korea's blue crabs are also known as a major fishing resource in the West Sea, with 23,000 tons, or 85%, of the total catch of 27,000 tons last year being caught in the West Sea. On the other hand, the catch of blue crabs in the East Sea has steadily increased over the past 10 years, increasing from 23 tons in 2020 to 130 tons last year, a 5.7-fold increase in three years. Additionally, blue crabs were found in some southern coastal waters such as Yeosu in Jeollanam-do and Goseong in Gyeongnam, as well as in Jeju Island.
