Our Sharkulator methodology behind the tool is based on six calculation steps, starting from the number of bowls of shark fin soup, through key product and weight conversions, to a live shark equivalent. The methodology focuses on producing an estimate for blue shark (Prionace glauca) as it is by far the most abundant species in the global shark fin trade.
We have also applied product data from Hong Kong, which was collected during a dedicated research project conducted by WWF-Hong Kong in 2011. Hong Kong is not only world’s largest shark fin trade hub but also one of the largest consumers of shark fin per capita.
The intention of WWF Sharkulator is to provide science-based conversion estimates, primarily for public communications around shark fin demand reduction, and potentially for monitoring of impact, rather than for management or regulatory purposes where a higher degree of accuracy may be required. As better data becomes available, incorporating those into the conversion process may allow for increased accuracy and representativeness of the conversion estimates, and thus an expanded range of application.

(7 Sept 2021) A major study re-assessing the IUCN Red List status for all sharks, rays and chimaeras reveals that over 1/3 of all these species are now at risk of extinction caused by overfishing. Governments and regional fisheries bodies must act now to stop overfishing and prevent a global extinction crisis.Continue Reading
(30 August 2021) - More than two dozen new faces were among the familiar ones as the latest annual whale shark survey came to a close in Donsol, Philippines, ahead of Whale Shark Day 2021. The World Wide Fund for Nature (WWF) Philippines identified 58 individual whale sharks during the organization's 2021 population survey, held annually off the coast of Donsol.Continue Reading
