A paper recently published in the journal Fish and Fisheries explores 70 years of visual fish census techniques, including the REEF Volunteer Fish Survey Project. The paper, titled "Global Analysis of Shallow Underwater Fish Observation Research: 70 Years of Progress, Persistent Geographic Biases and a Path Forward," was one output of a multi-year Working Group called CoNCENSUS.
Winter months always bring news of one of REEF's key conservation science effots - the Grouper Moon Project, a multi-decade conservation success story protecting one of the Caribbean’s most extraordinary natural events: the largest known spawning aggregation of the endangered Nassau Grouper. We are excited to share a new short video that tells this story. Check it out on REEF's YouTube channel "We Speak Fish".
We are excited to welcome Tom Sparke to the REEF Team as Communications Manager. Tom joins us with experience spanning marine science,conservation, and storytelling. He is an accomplished underwater videographer and avid scuba diver. Tom earned a BSc in Marine Biology & Oceanography and an MSc in Tropical Coastal Management from Newcastle University in the United Kingdom. His involvement with REEF began in 2016 as a volunteer scientific diver with the Grouper Moon Project, and he has participated every year since.
There is nothing better than escaping the cold winter months of January. Join REEF on our Field Survey Trip to Palau, January 17-27, 2027. A 10-night adventure aboard the Palau Aggressor II, timed perfectly with the full moon to witness the spectacular spawning of Red Snapper, Moorish Idols, and Orangespined Unicornfish. Following the Best of Palau itinerary, this trip promises world-class diving with incredible biodiversity. On our previous Palau REEF trip, we encountered rare marine life such as the elusive Blueback Pygmy Angelfish, Harlequin Grouper, and Helfrich’s Dartfish.

The 2026 Florida Keys Lionfish Derby & Arts Festival is just around the corner, and we’re gearing up for an exciting weekend of conservation, community, and creativity this April! This event combines hands-on invasive lionfish removal with local art, science, and education. Here’s a look into what to expect:
April 23 - Kick-off Party & Captain’s Meeting (5-7:30 PM)
As REEF continues to grow in scope and scale, our leadership must grow along with it. Last year, the Board of Trustees made the strategic decision to expand from nine to eleven members to better support our mission. We are thrilled to announce that Dr. Julia Parrish and Will Ribbens officially joined the Board on January 1, 2026.
Both Julia and Will bring a wealth of expertise, a passion for citizen science, and a deep-rooted love for the marine environment. Please join us in welcoming them to the REEF family!

Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long-term, representative information on key fish populations and habitats to inform management and policy. Underwater fish observation techniques, such as Underwater Visual Census (UVC - which includes the REEF Volunteer Fish Survey Project), stereo-Baited Remote Underwater Video (stereo-BRUV), and Remotely Operated Vehicles (ROVs), all play a key role in sustaining long-term data collection.
Join us for a FREE marine life education class at the Trans World Radio (TWR) Bonaire Headquarters on Thursday, February 26 at 7:00 pm AST!
This month’s session, "Lookalikes: Spot the Difference," will focus on those species of reef fish that seem almost identical but have key differences once you know what to look for.
