**Antarctic blue whales are slowly recovering from whaling, with their population now estimated at 4,018, about 2% of pre-whaling numbers.**

Antarctic blue whales, the largest blue whales on Earth, are showing signs of recovery from extensive whaling, with their population estimated at approximately 4,018 individuals in 2024. This marks a significant increase from about 418 whales recorded in 1973, but still represents only about 2% of their population prior to whaling. The data comes from a computer model developed by a team led by Zoe Rand at the University of Washington’s School of Marine and Environmental Affairs, in collaboration with researchers from the US, Australia, Japan, and South Africa. This assessment is the first comprehensive evaluation of Antarctic blue whales in over 20 years.

## Historical Context

The decline of Antarctic blue whales was severe; in 1904, whalers killed 11 individuals, and by 1930, that number surged to 30,405 in a single year. By the time commercial whaling was banned in 1963, a total of 347,662 whales had been killed. The team estimates that around 206,000 Antarctic blue whales existed in the Southern Ocean before whaling began. Despite the ban, illegal whaling continued for about a decade, further impacting their numbers. The current population growth rate is estimated at 4.5% per year, slower than the 7.3% reported in the last assessment in 2004.

## Challenges Ahead

While the population is increasing, the recovery is from a critically low baseline. The model suggests that even if growth continues, Antarctic blue whales may not reach 60% of their pre-whaling numbers until around 2102. Additionally, competition for food sources like Antarctic krill may hinder their recovery, as other whale species are also rebounding. The authors emphasize the need for improved monitoring and research to understand the future of this species in a changing Southern Ocean. The full study was published in the journal Endangered Species Research.
