Scientists and project volunteers from REEF and our partner institutions, the Cayman Islands Department of the Environment and Oregon State University, are getting ready for another year of the Grouper Moon Project. The team will be in the field for two weeks beginning on the full moon, January 30. Since 2001, REEF has led the Grouper Moon Project, a multi-faceted, collaborative research effort in the Cayman Islands aimed at better understanding Nassau grouper reproduction and the role that marine reserves can play in the long-term protection of this endangered species.
In 2003 the Cayman Island Marine Conservation Board instituted an 8-year fishing ban on Nassau grouper at all historically known aggregation sites in the Cayman Islands. This followed the discovery by fisherman of 7,000 aggregating Nassau grouper on the west end of Little Cayman in 2001 and the subsequent harvest of 4,000 of those fish over two spawning seasons. At the time, all other known Nassau grouper aggregations in the Cayman Islands had become inactive due to over-harvest. Thanks to a three-year grant awarded in 2008 by the Lenfest Ocean Program of the Pew Charitable Trusts, REEF is conducting research through the Grouper Moon Project to evaluate the current status of the Cayman Islands spawning aggregations and the effect of these harvest protections -- “The reproductive biology of remnant Nassau grouper stocks: implications for Cayman Islands Marine Protected Area (MPA) management”.
The broad goals for the 2010 spawning season are to continue monitoring recovery in the large spawning aggregation on Little Cayman, and to expand research into the fate of remnant spawning aggregations on Cayman Brac and Grand Cayman. Watch future issues of REEF-in-Brief for field season results and what's next for the protection of spawning aggregations in the Cayman Islands as the current harvest ban is due to expire.

World-wide declines in shark and ray populations have prompted the need for a better understanding of their patterns of distribution and abundance. While much of the focus has been on the larger species of sharks, little attention had been paid to the most frequently sighted elasmobranch species in the greater-Caribbean, the yellow stingray (Urobatis jamaicensis). Despite being relatively common and listed as Least Concern on the IUCN Red List, little was known about the status of this species. Unfortunately, it has been quietly declining. Dr. Christine Ward-Paige and her colleagues at Dalhousie University worked with REEF's Director of Science, Dr. Christy Pattengill-Semmens, to examine the status of yellow stingray. The results of this study were recently published in the scientific journal, Environmental Biology of Fishes. Click here to read the paper.
The study used 83,940 surveys collected by REEF surveyors in the western Atlantic. In total, yellow stingrays were observed on 5,658 surveys (6.7% sighting frequency) with the highest occurrence in the regions surrounding Cuba. Overall, sighting frequency declined from 20.5% in 1994 to 4.7% in 2007. However, these trends were not consistent in all regions. The strongest decline occurred in the Florida Keys, the most sampled region, where trends were similar among all areas, habitats and depths. Possible explanations for these changes include habitat degradation, exploitation (this species is collected for medical research and the aquarium trade), and changes in trophic interactions. The results of the study suggest large-scale changes in yellow stingray abundance that have been unnoticed by the scientific community. This study also highlights the value of non-scientific divers for collecting data that can be used to understand population trends of otherwise poorly studied species.

This month we feature Patricia Broom (REEF member since 2004). Pat is a member of REEF's Advanced Assessment Team in the Tropical Western Atlantic and has conducted 277 surveys in three of REEF's regions, including some of the first in our newest region, the South Pacific. Here's what Pat had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
About ten years ago while reading a favorite dive magazine I noticed an announcement about an introductory fish identification trip sponsored by REEF and led by Paul Humann. The love of REEF was born!! I responded to the advertisement, encouraged my brother to join me and attended that Field Survey trip. We joined a group of equally dedicated divers eager as we to learn about fish and how to identify them. Paul was a great teacher, very patient and concerned that we not only learn about fish but care about them and the ocean we love.
If you have been on a REEF Field Survey, where and what was a trip highlight?
One of my most memorable surveying moments occurred that week on Paul's trip. On a night dive of a very old wreck with exposed wooden beams I saw my first queen parrotfish in their nighttime cocoons. Each parrot fish occupied a space between two beams framed by basket stars in full bloom. It was a magical sight. I try to take two or three REEF trips a year, they are a great way to learn more and dive with great people. In addition to the regular ID trips, I have really enjoyed the REEF Behavior Trips that are led by Ned and Anna DeLoach. It really completes the learning experience! It is a beautiful sight to watch damselfish guard their algae gardens from predation, observe cooperative hunting, or watch a three foot Midnight Parrotfish at a cleaning station with open mouth and flared gills.
What inspires you to complete REEF surveys?
Prior to that introductory course, I had been diving the Caribbean for twenty plus years. I witnessed the decline in fish numbers and species as well as reef degradation and wondered how many more years I could dive before there was nothing to see! REEF offered me a reason to continue diving, now there was opportunity to give back and enjoy diving again.
Do you have a favorite local (or not) REEF field station or dive shop?
I have found great enjoyment in Cozumel at the REEF Field Station at Aqua Safari, led by Sheryl Shea. She is a gifted teacher determined to make advanced assessment divers of all of us! It just so happens a few of my favorite fish are in Cozumel, the Splendid Toadfish, Sargassum Triggerfish, and Cherubfish, to name a few.

REEF is once again partnering with CEDAM International to support an educator to participate in one of our REEF Trips. The selected Lloyd Bridges Scholar will join Paul Humann on the Little Cayman Field Survey in July 2013. The goal of the scholarship program is two-fold: One, to have educators experience the wonders of the underwater world and then be able to share these wonders with his or her students or constituents. Two, to have these inspired individuals go out and do what they can to help protect one of the world’s most fragile ecosystems. To be eligible, applicants must be a certified scuba diver, a teacher (elementary or secondary level), or actively engaged in an education program at an institution or environmental organization, such as an aquarium, science center, or relevant non-profit organization. More information and application information is posted on the CEDAM website.
The 2013 REEF Trips Schedule includes destinations in the Caribbean, Canada, and tropical Pacific. These trips offer a great introduction to fish identification for novice fishwatchers, and are a fun way for experienced surveyors to build their life list while interacting with fellow fishwatchers. Each trip features daily classroom seminars and a full diving schedule. Complete package details and prices can be found online at www.REEF.org/trips.

This month we highlight Carl Gwinn, a REEF surveyor in California. Carl joined REEF in 2001 and has conducted 328 surveys. He is a member of the Pacific Advanced Assessment Team. Here's what he had to say about REEF:
When and how did you first volunteer with REEF or become a REEF member?
Not long after we started to dive in California, my wife and I saw an advertisement for a fish ID seminar and survey trip out of Santa Barbara. We couldn’t make the trip, but we attended the seminar, learned quite a bit about fish, and started doing surveys. As we dived more, we became more engaged and more serious about it. We went on some trips and filled out quite a few surveys. Lately, I’ve had to slack off, because of work responsibilities, but I’m hoping to do more in the future.
What is your favorite part about being a REEF member?
Being a citizen scientist! I enjoy doing the dive, but it’s also making a contribution to human knowledge. So, the experiences of the dive add a little something to human knowledge, rather than being merely for my own entertainment. I also think REEF does great work in getting people to experience, appreciate, and learn about the ocean.
If you had to explain REEF to a friend in a couple of sentences, what would you tell them?
Dive for science! Identify and count fish while enjoying your dive.
In your opinion, what is the most important aspect of REEF’s projects and programs?
Of course the data are important. But I think that the education aspect is also really important. People appreciate more what they understand. Counting fish can help them to realize how complicated and interconnected the ocean is. It’s also vulnerable, but has tremendous regenerative capacity. That’s something that surveyors can experience directly, after gaining a bit of knowledge.
Do you dive close to where you live, and if so, what is the best part about diving there?
My favorite place to dive is probably Refugio State Beach, not far from my house. I’ve done over 200 dives there. I like it because it’s easy to get in and out, and is relatively well sheltered from the swell. Once you get in it has a wide variety of different habitats in a small area. You can really see how the populations of fish and invertebrates change, both with the seasons and in ways that never repeat. The beach there tends to get overcrowded, but usually once you get offshore it is pretty empty.
What is the most fascinating fish (or invertebrate) encounter you’ve experienced?
Certainly my most memorable encounter was being attacked by a Giant Pacific Octopus. He tore off my mask and my regulator, and tried to yank off my hood. I was diving in the Olympic Marine Sanctuary in the Strait of Juan de Fuca, on a REEF survey trip. I slammed my regulator back in, and surfaced from 50 feet depth with the octopus on my head. Its suckers left hickeys all over my face, which lasted about 10 days! The photo has become widely circulated on the internet! Although my dive buddy had a camera, he was enjoying a crevice full of sculpins too much to notice the encounter: my only regret is that he didn’t get a series of photos.
What is your favorite fish or marine invertebrate?
Probably my favorite kind of fish is the rockfish. There are lots of different species, and sometimes they seem to blend into one another, so ID can be a challenge. They exhibit some interesting types of behavior, sometimes species-specific. I love to see the schools of juvenile and smaller rockfish: they have bright, clear markings and seem curious. They change from year to year, as the different species have more or less success in recruitment. And, they are hope for the future.
Do you have any surveying, fishwatching, or identification tips for REEF members?
Jump in. I remember taking a boat trip to the Naples Seamount and Platform Holly. The visibility started at 5 feet and got worse with each dive, and the surge was over 3 feet at depth. On the way back to the harbor we stopped at the Goleta sewer pipeline, which runs from shore to a few of miles out to sea, and has some good fish in the rocks covering the pipeline. I decided to skip the dive, I’d had enough. My nap was interrupted by a lot of shouting up on deck. A gray whale had swum up to a few of the divers, on the bottom, and inspected them with its enormous eye. I wish I’d seen that! So, jump in.
What is your most memorable fish find and why? Is there a fish (or marine invertebrate) you haven’t seen yet diving, but would like to?
I remember spotting an unusual rockfish on a dive off Santa Cruz Island: later identified as a xanthic-melanthic gopher rockfish (or black-and-yellow rockfish) south of Santa Rosa Island. It was nearly completely yellow. It was probably the most unusual fish I have seen: essentially a mutant. I managed to get a photo. What haven’t I seen yet? I haven’t yet managed to spot many of the local fish, some common: an embarrassing lapse! I’d like to see more and different kinds of sharks, spot some turtles (they show up around here occasionally), watch a few different kinds of whales and dolphins swim by underwater. I would love to see a white abalone underwater: they are extremely rare.
As we celebrate this holiday season, I am happy to report that REEF is also celebrating another successful year of protections for ocean habitats and the critters that live in them!
Please take a moment to make sure REEF continues this critical work. You can contribute securely online at www.REEF.org/contribute or call REEF Headquarters at 305-852-0030.
