Notes

  • S1378 - 37 increased previous estimate of 1 - 10,000 on basis of additional data from Yellow Sea. 413: 5,504 recorded in AWC 2003 in South Korea.
  • S6826 - Cao et al. 2009 proposed <10,000 baed on counts in China. However, as the population in Korea is at least 5,000, this is used as the minimum.
