Notes

  • S8465 - This estimate is based on a census made throughout the USSR in 1987 (Scott & Rose, 1996). However, the maximum count total during IWC was only 42,188 individuals in 2003 and recent 5-year-mean was as little as 4,699 individuals, probably due to reduced efforts.
  • T6463 - Scott & Rose (1996) reported a large increase. However, there is no information about the current status of the population.
  • S8918 - See CSR 6 and Sheldon (2017).
