Notes

  • T7751 - The IWC analysis reports a stable trend for 2011-2020 (0.9887) and an increasing trend for 2008-2020 (1.0122). Increases reported in Korea and Japan from 1990s-2012, with likely declines in China (Hashimoto & Sugawara 2013), but additional surveys needed in CN to clarify situation.
