If you haven't checked out the online REEF Store recently, now is a great time to do some shopping. It's a great place to get field ID reference guides, REEF survey materials, REEF gear, and lionfish field gear. We have added several new items recently, including:
- Ray Troll's "Dive Bar" shirt with REEF logo, click here
- Lionfish 3-D Puzzle, Lionfish Plush, and Lionfish Phone Case, click here
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 Roger Skillman. Roger has been a REEF member since 2009, and has conducted 45 surveys. Despite being landlocked in the Smoky Mountains, he is an active surveyor in the Carolinas and Florida. He also teaches SCUBA and incorporates REEF in to his classes! Here's what Roger had to say about REEF:
What’s your favorite part of REEF surveying?
Every month, scientists, government agencies, and other groups request raw data from REEF’s Fish Survey Project database. Here is a sampling of who has asked for REEF data recently and what they are using it for:
- Scientists from NOAA Southeast Fisheries Science Center are evaluating the status of Lesser Electric Ray in the Caribbean.
- A scientist from NOAA Northwest Fisheries Science Center Fisheries Conservation Biology Division is including REEF data in an evaluation of threatened rockfishes in Washington State.
As the year winds down, we still have a few educational REEF Fishinars remaining. Check out the full schedule at www.REEF.org/fishinars. And keep an eye on that space because we will be adding new ones for 2015 soon. Fishinars coming up include:

A recent study published in Ecology and Evolution offers a new approach to traditional mark and recapture studies while providing valuable insight into the growth and movement patterns of invasive lionfish. Lad Akins, Dr. James Morris, and Dr. Stephanie Green teamed up to develop a novel way of visually tagging fish underwater, minimizing both tagging time and fish trauma.
Information on fish movement and growth is primarily obtained through the marking and tracking of individuals with external tags, which are usually affixed to anesthetized individuals at the surface. However, the quantity and quality of data obtained by this method is often limited by small sample sizes owing to the time associated with the tagging process, high rates of tagging-related mortality, and displacement of tagged individuals from the initial capture location.
