AI Insight
A new study published in the African Journal of Marine Science shows that blue and fin whale populations are recovering in the southeastern Atlantic Ocean more than 40 years after commercial whaling ended. The research compiled over 60 years of confirmed whale sightings and strandings from Namibia and South Africa's west coast, finding that 95% of all observations occurred since 2012. While overall population numbers remain low, the marked increase in recent sightings suggests these critically depleted species are beginning to return to their historical habitats.
Why it matters
This recovery indicates that international conservation efforts and the ban on commercial whaling have been effective in allowing these endangered species to slowly rebuild their populations. The findings provide hope that even severely depleted marine mammal populations can recover given sufficient protection time, though continued monitoring and conservation remain essential.
Understand the Science
More than 40 years after the end of commercial whaling, new research reveals a recent increase in sightings of the world’s two largest whale species in the southeastern Atlantic. The findings, published in the African Journal of Marine Science, compiled more than 60 years of confirmed sightings and strandings from Namibia and South Africa’s west coast. Although overall numbers remain low, sightings of both species have increased markedly in recent years—with 95% of observations recorded since 2012.
