REEF Fish Count Diving in Islamorada
Shared Trip
Join REEF's citizen science fish survey diving programFish ID class at 10am, followed by two guided divesExpert dive masters maintain 1:6 ratio for personalized experience
Want to make your dives count for something bigger? This July, join Key Dives for the REEF Great Annual Fish Count – a chance to become a citizen scientist while exploring some of Florida's best coral reefs. You'll start with a fish identification class at REEF's Ocean Exploration Center, then hit the water for two guided survey dives where every fish you spot contributes to vital conservation data. It's diving with purpose, and you'll be amazed how much more you notice underwater when you're actively looking for specific species.
Your day kicks off at 10am with REEF's fish ID session at their Ocean Exploration Center in Islamorada. This isn't your typical classroom experience – you'll learn to identify common Caribbean reef fish using visual guides and real-world examples. The instructors know these waters inside and out, and they'll share tricks for spotting cryptic species and distinguishing between similar-looking fish families. After lunch, meet up at Key Dives at 12:30pm for two shallow survey dives. These sites are perfect for fish counting – healthy coral formations with good visibility and diverse marine communities. You'll be diving at a relaxed pace, giving you time to properly observe and record what you see. The whole experience runs about six hours, but it flies by when you're focused on the task at hand.
Key Dives provides all your essential gear – tanks, weights, and everything needed for the survey work. You'll dive with one of their top-rated dive masters (they won Best Dive Masters in the Keys for 2026) at a comfortable 1:6 ratio, so there's plenty of personal attention. The survey technique is straightforward but requires some practice. You'll swim a designated route, recording every fish species you can identify within a specific area. Don't worry if you're new to fish identification – the morning class prepares you well, and your dive master will help spot species you might miss. These are shallow reef dives, typically 30-60 feet, with mild currents and excellent visibility most days. After each dive, you'll have hot freshwater rinses available on the boat, plus fresh fruit and cold water to keep you energized between dives.
Islamorada's reefs are home to an impressive variety of Caribbean fish species, making it perfect for survey diving. You'll likely encounter schools of blue tangs and yellowtail snappers cruising the reef face – these are easy identifications that boost your confidence early in the dive. Parrotfish are everywhere here, from the vibrant stoplight parrotfish to the massive rainbow parrotfish that can reach over three feet long. Watch for their constant grazing behavior as they scrape algae off coral surfaces, creating those distinctive crunching sounds. French angelfish and gray angelfish are common sightings, often swimming in pairs and showing little fear of divers. In the coral crevices, keep an eye out for the brilliant yellow and blue colors of queen angelfish – they're stunning but can be shy around bubbles. Wrasses are abundant too, with the colorful bluehead wrasse and Spanish hogfish being reliable spots for your survey sheet. The diversity here means you'll easily identify 20-30 species per dive, sometimes more if you're sharp-eyed and the conditions cooperate.
This REEF survey experience offers something most dive trips can't – the satisfaction of contributing real scientific data while enjoying world-class diving. Key Dives' commitment to conservation goes beyond this single event; they donate 2% of all dive revenue toward coral reef restoration, so your participation supports ongoing efforts to protect these ecosystems. The combination of education and hands-on citizen science makes this a standout choice for divers who want more than just sightseeing underwater. Plus, you'll walk away with improved fish identification skills that enhance every future dive. Spots fill up quickly during REEF's annual count, and with limited capacity, early booking is essential. Check Key Dives' 24-hour cancellation policy for peace of mind, and remember they provide full refunds if weather forces a cancellation.
Key Dives' spacious 42-foot Newton dive boat makes the perfect platform for your REEF fish survey adventure in Islamorada's crystal-clear waters. This roomy vessel comfortably handles up to 18 divers per trip, giving you plenty of space to gear up and relax between your two shallow survey dives. The boat's hot freshwater showers let you rinse off after counting fish species, while the onboard cooler keeps you hydrated throughout the day. With guided dives at a 1:6 ratio from award-winning dive masters, you'll have expert support as you become a citizen scientist contributing valuable data to REEF's global fish database. The stable platform and professional crew make this conservation-focused diving experience both educational and enjoyable as you explore the Florida Reef Tract.
