Estimation of the maximum sustainable yield for Bora-Bora's reef fisheries following the Leenhardt's protocol. Visual surveys allowed us to estimate at 39.51 tons/km−2 in 2020 and 83.25 tons/km2 in 2022 yielding an average value of 58.8 tons/km2 (B), assuming that the fish population evolution follows a Von Bertalanffy Growth.
