Below the surface: data-driven approaches for a deeper insight into global large pelagic fisheries

Large pelagics, such as tuna and sharks, are crucial for marine ecosystems. However, their biomass has decreased by 60-70%, largely due to industrialized fishing since the 1950s. My research uses multiple lines of evidence, including fisheries-dependent and fisheries-independent datasets and methodologies, to confirm existing concerns of systematic and widespread overfishing of large pelagics globally. I also provide new insights into the status of currently undermanaged and unassessed large pelagics. This research emphasizes the need to implement alternative methods to inform and adapt management strategies for these highly vulnerable and threatened species as a first step to rebuilding overexploited populations globally.
