[...]we account for selectivity by focusing our fisheries-independent spatial estimates directly on individuals that were actually caught by the focal fisheries. [...]the commercially valuable sharks that we tracked are seldom discarded by major high-seas longlining fleets8, indicating that an implicit assumption of a fishing mortality probability of one does not substantially overestimate the mortality that occurs. Regarding FEI being related to fishing-induced shark mortality, we stated1 that the significant positive relationship between Food and Agriculture Organization (FAO) fishery landings data and individual-species mean FEI "implies that the index reflects fishing-induced shark mortality". [...]we disagree that our analyses do not support our conclusion of limited spatial refuge for pelagic sharks from current levels of fishing effort in Areas Beyond National Jurisdictions (ABNJs).
