Hammerheads Up Close: The Science Behind the Spectacle w/Dr Katy Ayres
Protecting key sites lets sharks persist
Sharks decline less when protected areas safeguard aggregation and nursery sites, because data can justify spatial refuges; but overall recovery is hard to prove when fishing removes whole ecosystems and climate shifts confound signals.
“Sharks are the problem” is incomplete
Overfishing harms more than sharks: removing predators cascades across trophic levels, yet it’s difficult to show evidence because fisheries also harvest shrimp and bycatch simultaneously, obscuring cause-and-effect.
Drone surveys shift conservation from counting to targeting
Drone-based coastline video enables consistent, non-invasive abundance mapping and even AI counting, revealing movement shifts (blacktips moving south after orca arrival) and enabling future nursery-site prioritization.
