Abstract

Our previously published paper (*1) provided global fine-scale spatiotemporal estimates (1° × 1°; monthly) of overlap and fishing exposure risk (FEI) between satellite-tracked shark space use and automatic identification system (AIS) longline fishing effort. We did not assess shark mortality directly, but in addition to replying to the Comment by Murua et al., we confirm - using regression analysis of spatially matched data - that fishing-induced pelagic shark mortality (catch per unit effort (CPUE)) is greater where FEI is higher.
