Although WWF and other NGOs have been campaigning for over a decade to reduce the unsustainable consumption of shark fin soup in Asia, nobody was able to estimate how many sharks and rays could actually be saved when consumers chose to go fin-free. Development of any methodology to estimate that was hindered by the lack of relevant market data as well as large diversity of shark species, animal sizes, and types of fins that ended up in soup.

WWF Sharkulator is a new science-based methodology to estimate how many individual sharks can be saved based on the number of bowls of shark fin soup not consumed. By visualising the impact of their decision to go fin-free on these increasingly threatened marine creatures, we hope that WWF Sharkulator will encourage more people to say no to shark fin soup and as a result, support our long-term work to reduce the unsustainable demand for shark fin in Asian markets.

To get started, enter the number of bowls of shark fin soup not consumed into the Sharkulator tool on this page and click the “SAVE SHARKS” button. For example, if you attended a wedding banquet where shark fin soup was served but you chose not to eat it, you can count how many sharks you have “saved”. If your company is planning to organise a corporate dinner in the future and no shark fin soup will be served, our tool will tell you how many sharks your company will “save”. Try out the tool now – the data you enter is not being recorded.​

WWF Sharkulator is now available in English, Traditional Chinese, Simplified Chinese, Bahasa Indonesia, and Bahasa Malaysia.
