Tagging and recapture data are crucial for understanding shark migration and distribution. Shark tagging involves attaching small tags to sharks, enabling researchers to monitor their movements, growth, and behaviours.

The Cooperative Shark Tagging Program (CSTP), initiated by the Northeast Fisheries Science Center in 1962, has expanded to include over 7,000 volunteers who have tagged more than 295,000 sharks from over 50 species. This initiative has highlighted the importance of long-term ecological monitoring and the role of sharks in ocean ecosystems.

Various tagging methods, provide unique data on migration, population structure, habitat use, and species-specific survival and reproduction patterns. The information from tagging has assisted NOAA in defining essential fish habitats (EFH) for 38 federally managed shark species, which are vital for protecting nursery grounds and determining breeding and feeding areas.

The insights gained are foundational for effective stock assessments, bycatch reduction strategies, and seasonal closures to ensure long-term sustainability.

World Tuna Day is a reminder that the choices on our plates are connected to life beneath the surface.
Tuna are not just a popular food source. They are powerful ocean predators, part of complex food webs, and often linked to wider conservation issues such as overfishing and bycatch of sharks, rays, turtles, and seabirds.
It is not always easy to change habits or food preferences, and nobody is perfect. But every conscious decision matters. Choosing more responsibly sourced seafood, reducing unnecessary consumption, and learning where our food comes from can help shift industries that are harmful to our oceans.
Protecting tuna also means protecting sharks, marine ecosystems, and the balance of ocean life.
This World Tuna Day, let’s choose with awareness. 💙

Marine Protected Areas are a key tool in ocean conservation, helping to safeguard biodiversity, restore ecosystems, and support sustainable use of marine resources.
From protecting critical habitats to enabling species recovery and spillover effects, their success depends on thoughtful design, effective management, and ecological connectivity.
Ultimately, healthy oceans rely on connected ecosystems where protection goes beyond boundaries and supports life across the entire marine system.
