This publication from the Grouper Moon Project addresses the question of where fertilized eggs go after being released by Nassau Grouper at their spawning site off the west end of Little Cayman. On nights of spawning in 2017, researchers physically tracked clouds of tiny, transparent Nassau Grouper eggs through the night with an underwater microscope developed by scientists at Scripps Oceanography. Results show that fertilized eggs from Little Cayman floated back onto reefs on the island.

REEF Ocean Explorers Education Programs engage and inspire learners of all ages to protect and conserve our oceans. Our programs topics include biology, ecology, citizen science, and invasive species, and are designed to help participate understand the importance of marine conservation and how they can make a difference. To reach new audiences and connect even more people with ocean conservation, we're also highlighting connections between arts, humanities, and science.
REEF online programs are free and open to everyone! Here's what's coming up this month:

We're gearing up for summer, and that means Lionfish Derby season is here! We're excited to share that registration is now open for the 2023 REEF Florida Keys Lionfish Derby & Festival on Sept. 7-10. The event includes two full days of lionfish hunting, followed by a lionfish festival at Postcard Inn Beach Resort & Marina in Islamorada, Florida. The family-friendly festival takes place on Sunday, Sept. 10 and includes lionfish scoring, tastings, educational demos, games, crafts, raffles, and activity booths from arts and conservation vendors.
We are encouraging Tropical Western Atlantic REEF surveyors to be on the lookout for a skin condition that is affecting reef fish in the Caribbean. Black Spot Syndrome (BSS) affects many reef fish but can easily be observed on Ocean Surgeonfish, especially when they are pale in color. The black spots are usually on the fins and skin of the affected fish. In many cases, Black Spot Syndrome is caused by a trematode parasite, Scaphanocephalus spp., which moves from marine snails to reef fish and ultimately into osprey, which consume the infected fish.
If you've dreamed of diving the Red Sea, this summer is the perfect time to plan a trip! There are just a few spaces left on our Red Sea Field Survey Trip happening on July 6-16, 2023. This ten-day liveaboard trip offers the chance to explore the shipwrecks, reefs, and pinnacles of the Egyptian Red Sea. REEF Trips are a great way to meet fellow marine life lovers and learn more about the fish you see on your dives. Trips are open to all surveyor experience levels, from beginner to expert! Here are even more reasons to sign up today:
