Race Week is June 7–13, 2026, and registration closes June 15 — or as soon as shirt supplies run out, whichever comes first. If you’ve been meaning to sign up, this is the moment.
Mark your calendar! We have two upcoming Fishinars, REEF’s free online fish ID webinars, both led by REEF’s Field Survey Trips Program Manager and fish enthusiast Stacey Henderson. Whether you’re prepping for your next dive trip or just curious about life beneath the surface, these sessions are a great way to sharpen your ID skills from anywhere.
Thanks to the efforts of many REEF members and our funding partners, the SMILE (Size Matters: Innovative Lengths Estimates) Project has made progress in advancing conservation technology for fisheries science and management. Size data is a crucial component of fish population monitoring to understand trends in population size, growth, age and reproductive potential, and fishing pressure. Collecting these data is often resource-limited for fisheries managers, leading to a data gap for management and conservation.
Our group of 20 participants had an incredible 9 days on our Field Survey Trip to Misool Eco Resort, in Indonesia. From close encounters of the Manta kind to vibrant schools of fish, we only scratched the surface of what this unique place had to offer. We dove deep pinnacles, shallow coastal slopes, and mangrove lagoons, finding an abundance of different species. We found species such as the Denise Pygmy Seahorse, Squarespot Anthias, Banded Archerfish, and 3 shark species: Blacktip, Tasseled Wobbegong, and Epaulette Shark.
Last month, we released the 2027 REEF Field Survey Trips schedule, along with a few trips in 2028 and 2029. We have plenty of exciting destinations planned! REEF Trips are led by marine life experts, and include diving, fish ID classes, and fun with like-minded friends. Divers, snorkelers, and families are welcome on REEF Trips.
With almost 350,000 hours of underwater visual survey time collected at more than 17,000 locations around the world over the last 33 years, the REEF Volunteer Fish Survey Project represents one of the most comprehensive marine sightings databases available. We are grateful to you and the thousands of other volunteers who have contributed to this amazing citizen science effort. We are excited to share two recent uses of the REEF database for conservation and ecological studies.
Ever submitted a survey and noticed it did not show up in your account right away? No worries — it takes several weeks, at least, for your surveys to appear in your survey log. Here's a breakdown of how it works.
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.
Join us as we celebrate you and the power of community-driven science. Research findings show that citizen science is an extremely impactful tool when it comes to furthering scientific research. Your contributions to the Volunteer Fish Survey Project are a prime example of this, collecting critical data needed for marine conservation. Every survey you submit helps make a huge difference!
