Why care

Whale sharks get subjected to human-induced threats within the fishing industry when they are swimming close to land to feed. They get caught as bycatch, injured by motor boat propellers or subjects for illegal shark fin trade.

  • Puts pressure on politicians to create legislation for the protection of whale sharks and other marine life.


  • Stella has identified and documented over 400 juvenile whale sharks since 2015.

  • Began tagging juvenile whale sharks in 2016 and is now tracking a large population of them.

  • Put pressure on politicians by generating scientific proof of the need to increase protection.

  • A cross-border conservation pact was signed between 126 countries in 2017 to increase the protection of sharks and other migratory species.

  • Have developed a code of conduct intending to keep the animals safe from boats in the area. Local operators have implemented this, but she is aiming to have even better legislation in place.
