The western South Atlantic humpback population of whales has grown up to 25,000 which is close to pre-whaling numbers.
In the 20th century the western South Atlantic population of humpbacks was diminished to only 450 whales. Over 12 years in the early 1900s whaling industry destroyed about 25,000 whales.
That rapid decline made scientist put protective measures in the 1960s. In the 1980s the International Whaling Commission issued a moratorium on all commercial whaling.
A new study estimates are made from air- and ship-based surveys. Advanced modeling techniques provide scientists with comprehensive look at the recovery of the humpback population. The study proves the efficiency of the new software that is now available to the public.
The revival of South Atlantic humpbacks is going to impact their ecosystem, especially in the sub-Atlantic waters of the South Atlantic Ocean. The influence of competition with other predators and climate change should be monitored and understood.
It is important to gather complete and accurate information to help safeguard these whales’ food source, krill, and to ensure the continual recovery of this population.
