Satellite tags on whales to give reason for their decline: The project will help scientists understand changes in the southern right whales’ migration and feeding patterns
The unit has, for the past 42 years, monitored the southern right whale population that breeds off the South African coast.
All these factors have resulted in lower numbers of southern right whales being seen off South Africa’s shores. The majority of female-calf pairs were observed between De Hoop Nature Reserve and Walker Bay. This number, the unit says, is higher than the numbers recorded in 2019 and 2020, but “still remains well below what we would expect under ‘normal conditions’. The number of unaccompanied adults continues to remain extremely low, as it has been since 2009, indicating that non-calving right whales are still not migrating to the South African coast as they used to.
