Making It Count - January 2016

Putting It To Work: A New Non-native Fish in the Gulf of Mexico

Author: Christy Pattengill-Semmens, Ph.D., Director of Science

Last year we shared an article about a new non-native fish, the Regal Demoiselle (Neopomacentrus cyanamos), showing up in the southwestern Gulf of Mexico. REEF surveyors in the Yucatan region of Mexico have since reported the species. And now a new publication co-authored by REEF staff Lad Akins documents that the species could become established and spread in the western Atlantic. The study incorporated a computer model to evaluate the the non-native species’ potential to impact native populations. On the basis of this work, it is foreseeable that the reefs presently harboring Regal Damselfish will likely see increased abundance of this damsel. Immediate attempts to eliminate the fish, therefore, should be focused in nearshore shallow waters spanning Veracruz to Frontera, Mexico. To find out more about this study, published last month in the journal Marine Biology, and to see a complete list of the 50+ scientific publications that have featured REEF data, visit www.REEF.org/db/publications.

The species is native to the Indo-Pacific and Red Sea. Similar in appearance to the native Brown Chromis, the Regal Damsel is distinguished by a yellow or white spot at the rear base of the dorsal fin, a dark spot behind the gill, and yellow rear margins of the fins and tail. In contrast, the native Brown Chromis is identified by dark margins on the tail and a dark spot at the base of the pectoral fin.

If you see this fish while doing a REEF survey, be sure to report it on your form in the unlisted fish section. Please also report detailed information on the sighting to REEF through the invasive species reporting page.

The Faces of REEF: Jason Feick

Author: Sasha Medlen, REEF Membership and Development Coordinator

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 Jason Feick, a REEF member since 2003. Jason has been an active surveying member in his home state of Massachusetts, and he's a proud member of the Advanced Assessment Team of Expert surveyors for the Northeast (NE) region. He has also done almost 200 surveys in the warmer waters of the Caribbean and Hawaii. To date, he's conducted 403 surveys. Here's what Jason had to say about REEF:

How did you first hear about REEF?

I came up from a dive in Curacao and everyone was talking about the fish they saw and when they asked me what I saw my response was “a bunch of blue fish (blue tangs) and a potato looking thing with fins (Porcupinefish.)” After that I was determined to know what I was looking at. Around the same time, I saw an advertisement for REEF in a dive magazine and went to the website, bought the Reef Fish Identification book, and have been during surveys ever since.

Do you dive close to where you live, and if so, what is the best part about diving there?

Yes, I live in Massachusetts and dive the chilly waters off Cape Ann, MA often. The best part about diving here is the variety of marine life in different geographic areas. South of Cape Cod the waters are slightly warmer and the marine life is very different. A short drive to Rhode Island and one can see juvenile tropical fish, while a little longer drive to Maine and one can see abundant invertebrate life, such as northern red anemones and stalked tunicates.

What is the most fascinating fish encounter you’ve experienced?

On a recent trip to Eastport, Maine, I videoed two Ocean Pout either having a territorial dispute or engaged in mating behavior. They started off lying side-by-side, then one bit the other in the back and shook vigorously. The second Pout then returned the favor to the first. They ultimately locked jaws as one of them pushed the other into my camera. This was quite an exciting interaction to witness. You can watch the video here.

What is your most memorable fish find and why?

A couple months ago I came across a goosefish while diving Halibut Shores, MA. This is an “ugly” (beautiful to me) fish that I thought I would never find. It is an ambush predator that uses a lure, similar to a frogfish, to draw in prey that it gulps up with its huge mouth. I saw its outline from a distance and couldn’t believe my eyes. As I got closer this crab came bumbling down a rock towards the goosefish. I was afraid the crab was going to chase the goosefish off and I wouldn’t be able to get a good picture. Well the crab did spook the goosefish, but he only moved a little and actually the movement shook off the silt that was covering the goosefish and I was able to get some good pictures and video of him. Top on my list of critters to see is an Atlantic Wolffish. My friends recently saw three of these on a dive I chose not to go one, D’oh!

Connecting With Classrooms in the Grouper Moon Project

Author: Christy Pattengill-Semmens, Ph.D., Director of Science

Scientists and volunteers from REEF, and our partners at Scripps Institution of Oceanography and Cayman Islands Department of the Environment, are wrapping up two weeks of field work on Little Cayman for the Grouper Moon Project. Since 2002, the collaboration has conducted ground-breaking research on the Nassau Grouper spawning aggregations in the Cayman Islands, to help ensure that populations of this iconic species recover. Around winter full moons, Nassau Grouper leave their home reefs and aggregate in mass to spawn. January didn't turn out to be the big month for spawning, and therefore our team will return for the February full moon. Nevertheless, many of the fish (at least 1,000) showed up at the aggregation site and our team kept busy collecting ongoing monitoring data (counts, size of fish, and documenting behaviors), field testing cutting-edge tools such as an underwater microscope, and running the Grouper Education Program.

In 2011, with funding from Disney Conservation Fund, REEF launched the Grouper Education Program to engage Caymanian students in the Grouper Moon Project. This exciting effort brings the Nassau Grouper in to elementary and high school classrooms through lesson plans and live-feed videos that connect classrooms with scientists in the field. The curriculum presents a multi-faceted view of Nassau Grouper in which students create their own understanding of this important fish. Key curricular concepts include the historical role of the species as an artisanal fishery throughout the Caribbean region, the grouper’s value as a keystone predator and its impact on local reef health, its role in today’s tourism-based economy in the Cayman Islands, and the conservation challenges facing Nassau Grouper given steep declines in populations. 

In January, we conducted four live-feed webcasts - three topside chats with scientists and one from underwater at a coral reef site along Bloody Bay Wall. All webcasts are archived on YouTube on TheGrouperTeacherREEF channel online here. Over 200 students from 17 schools participated.

Several interesting video clips and stories from the field were posted on REEF's Facebook page.

The work of the Grouper Moon research project – a collaboration between REEF and the Cayman Island Department of Environment has led to fishing restrictions at the aggregation sites and an increase in numbers of the endangered fish. To find out more, visit www.REEF.org/groupermoonproject. The Grouper Education Program is supported by a grant from the Disney Conservation Fund. In-kind logistics and technical support is provided by Peter Hillenbrand, Southern Cross Club, Little Cayman Beach Resort and Reef Divers, Cayman Airways, and FLOW Cayman.
