The first Bahamas Lionfish Derby, held on June 6 at the Green Turtle Club in Abaco, was a great success on many fronts. This test case for the Bahamas government was the first to allow (by special permit) the use of compressed air and spearing to remove lionfish in a derby type event. Organized by Abaco and Palm Beach resident Bobbie Lindsay and REEF, the one-day event drew 26 registered teams and brought in 1, 408 lionfish. Over $5,000 in prize money was awarded including $2,000 for the most fish by any team – 289 by team White Roach from Abaco. The largest fish award went to Team Panga with a 349mm fish and the smallest fish was brought in by Big T with a 57mm juvenile. Pre-event talks, including a school wide talk to the Amy Roberts elementary school, were well attended and generated significant awareness of the lionfish issue. Over 200 participants, residents and visitors attended the scoring and awards banquet and were treated to a lionfish tasting as well.
This is the first large scale event aimed at controlling lionfish populations in the Caribbean. More events are currently being organized in other areas and dates are being set for next year’s 2nd annual Abaco Derby. Special thanks goes out to the Green Turtle Club, Brendal’s Dive Shop and all of the great teams and volunteers who participated in the event. A great time was had by all and the lionfish population around Abaco was dramatically reduced.

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 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!
