ABSTRACT: Irion et al. (2017; Mar Ecol Prog Ser 577:251-255) disputed the population estimates of white sharks Carcharodon carcharias along the South African coastline as presented in Andreotti et al. (2016; Mar Ecol Prog Ser 552:241-253), claiming that both the genetic and the capture-mark-recapture results are poorly supported by the methods and data provided. Here, we provide additional analyses to refute the claims of Irion et al. (2017). We show that the integrated, balanced approach in Andreotti et al. (2016a) provides an objective and substantiated result.


KEY WORDS: Carcharodon carcharias · Effective population size · Capture-mark-recapture · White shark · South Africa · Conservation
