So we still don't have an estimate for the Southern hemisphere minke that the Japanese insist on hunting in a Sanctuary. The IWC Scientific Committee Chair has just said that still no estimate exists for this critical population.
However, what is reported, as noted by the UK, is that the population, whatever model is used to estimate the population size range, shows that the population has approximately halved between the last two major IWC surveys.
Japan says its because the whales are hiding under the ice. Sneaky those whales Maybe the whales are just learning to avoid any vessel with a Japanese flag on it.
