This study, co-authored by scientists from REEF's Grouper Moon Project, evaluated genetic connectedness between Nassau Grouper populations throughout the Caribbean. The authors obtained genetic tissue samples from 620 Nassau Grouper from 19 sites across 9 countries, including the Cayman Islands. They found evidence for strong genetic differentiation among Nassau Grouper subpopulations throughout the Caribbean. These results suggest that, despite a lack of physical barriers, Nassau grouper form multiple distinct subpopulations in the Caribbean Sea.
REEF Grouper Moon scientists co-authored a recent groundbreaking paper in the journal PLoS One that highlights the importance of regional conservation efforts aimed at spawning aggregations in the Caribbean. This study evaluated genetic connectedness between Nassau Grouper populations throughout the Caribbean using DNA markers. The authors obtained genetic tissue samples from 620 Nassau Grouper from 19 sites across 9 countries, including the Cayman Islands. They found evidence for strong genetic differentiation among Nassau Grouper subpopulations throughout the Caribbean.
In response to conservation concerns for inshore rockfish, Fisheries and Oceans Canada implemented a system of 164 rockfish conservation areas (RCAs) in British Columbia as part of the Rockfish Conservation Strategy. RCAs were established between 2004 and 2007. RCAs are not marine protected areas (MPAs) because they were not designated though any MPA legislative tool such as Canada’s Ocean Act, but rather through a fishery closure using the Fisheries Act. They can, however, be considered harvest refugia.
We've got lots of exciting, fun, and educational REEF Fishinars in store for you this year - featuring your favorite instructors and special guests alike. Check out the full schedule at www.REEF.org/fishinars. Fishinars coming up include:
REEF members are at the heart of our grassroots marine conservation programs. Over 50,000 divers, snorkelers, students, and armchair naturalists stand behind our mission.
This month we highlight Herb Gruenhagen. Herb has been a REEF member since 2001, and has conducted 208 surveys (all in his home state of California). He is a member of the Pacific Coast Advanced Assessment Team as an Expert Surveyor. Here's what Herb had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
We are excited to announce an exclusive opportunity for REEF members to pre-purchase the 4th edition Reef Fish Identification - Florida, Caribbean, Bahamas by Paul Humann and Ned DeLoach.

The new book is currently only available through the REEF online store. Purchase your copy today by clicking here.
A few weeks ago, in honor of Earth Day, REEF asked for your help in supporting our educational programs. Through classroom and field activities, these programs have inspired thousands of school children, young adults, divers, and researchers. If you haven't already made a donation, please consider making a difference in the life of a future ocean conservationist!

Restoration of a unique historic water cistern was recently completed at REEF Headquarters in Key Largo, FL. REEF’s Headquarters is located in the building that was originally the home of William Beauregart Albury, one of the earliest settlers of the Florida Keys. In August 2012, the Historical Preservation Society of the Upper Keys designating the building as a Key Largo historic site and “the oldest Key Largo home in its original location built in 1913.” As its original tenant, Mr. Albury lived in the residence for forty-two years.
We have one male share spot left on our REEF Trip to Honduras in June. Join us on this great dive vacation aboard the luxurious liveaboard MV Caribbean Pearl II! Dates are June 21 - 28. We will explore Utila, Roatan, and the banks in between. This special trip is led by two marine biologists, and we hear that whale sharks could be seen!
