  abstract = {{S}harks exhibit varied demographic strategies depending on both the species and the population location, which make them more or less vulnerable to fishing. {A}ccurate evaluation of local age and growth parameters is therefore fundamental for the sustainable management of their stocks. {A}lthough demographic parameters have been assessed for bull shark ({C}archarhinus leucas) populations in several locations of the world, this information is missing so far around {R}eunion {I}sland, in the south-west {I}ndian {O}cean. {T}o fill this gap of knowledge, age and growth data were gathered from the vertebrae of 140 individuals of {C}. leucas (77 females and 63 males, mostly adults) fished around the island between 2012 and 2019. {A}fter verification of the annual deposition of growth band pairs on these structures using relative marginal increment analysis on 40 individuals, band pairs were counted along the vertebral centrum for each individual. {T}hanks to this approach, growth was shown to significantly differ between male and female {C}. leucas around {R}eunion {I}sland, with respective von {B}ertalanffy growth model equations of {L}-t = 314 (1 - e-(0.0814(t+5.45)) and {L}-t = 321.5 (1 - e(-0.0999(t+3.420))). {I}ndeed, the females of the species fished in this area were significantly ({P} < 0.001) larger than local males, with an estimated difference in size of similar to 16.1 cm at 20 years old. {T}hey also apparently reach older ages, with an estimated maximum age of 33.50 years, against 29.75 years only for the males. {T}he estimated size at birth around the island is larger than elsewhere in the world, varying from 92.30 to 100.00 cm depending on the method used. {T}hese results confirm that the population of {C}. leucas around {R}eunion {I}sland exhibits a {K}-selected strategy, which makes it highly vulnerable to fishing pressure.},
