A group of marine biologists are challenging the findings of a recent study suggesting that South Africa’s White Shark population has not decreased, but simply redistributed eastwards to flee predation by Orcas.
Lester Kiewit speaks to Marine Biologist Dr Enrico Gennari of the Oceans Research Institute and the Department of Ichthyology and Fisheries Science at Rhodes University.He challenges the findings which suggest that South Africa's Great White Sharks have not decreased, but moved east to flee Orcas.In September 2023, the article “Decline or Shifting Distribution? A First Regional Trend Assessment For White Sharks in South Africa” was published in the open-access journal Ecological Indicators.
In a rebuttal article published in the same journal recently, titled “Uncertainty Remains for White Sharks in South Africa, as Population Stability and Redistribution Cannot be Concluded, by Bowlby et al ”, the group of concerned marine biologists highlight several issues with the methods and inferences made in the study mentioned above. They argue that the data do not support the theory of population stability or redistribution of South Africa’s White Sharks.
