What a year. From 477 brand-new surveyors slipping underwater for the very first time, to 27 dedicated divers each logging 100+ surveys, the Volunteer Fish Survey Project had another remarkable year of citizen science in 2025. Here's what the data tells us — and thank you for making every one of these numbers possible.
Since the program launched in 1993, REEF volunteers have contributed 322,338 surveys and 14.8 million sightings records from 17,900 sites around the world. In 2025 alone, 666 surveyors — including 477 first-timers — conducted 12,729 surveys at 2,545 sites globally.
