The 22nd annual Great Annual Fish Count (GAFC) is rapidly approaching! Will you be participating? We encourage local shops, dive clubs, and other groups to organize an activity anytime during the month of July (and often training events in June). You can view events already scheduled, and add your own, by visiting www.fishcount.org.
The concept behind the GAFC is to not only accumulate large numbers of surveys during the month of July, but to introduce divers and snorkelers to Fishwatching and conducting REEF surveys. Interested groups can offer free fish ID classes, organize dive/snorkel days, and turn them into fun gatherings! To find out more, contact us at firstname.lastname@example.org.
Ground-breaking invasive lionfish findings were featured in a paper published earlier this month in the scientific journal, Ecological Applications. The research was conducted as a collaboration between REEF, Oregon State University, Simon Fraser University, and the Cape Eleuthera Institute. The new study, conducted by Dr. Stephanie Green (OSU/REEF), Lad Akins (REEF), and others, confirms for the first time that controlling lionfish populations in the western Atlantic Ocean can pave the way for a recovery of native fish. Even if it's one speared fish at a time, data are showing that removals can be effective. And not every lionfish need be removed…the research findings document that reducing lionfish numbers by specified amounts will allow a rapid recovery of native fish biomass. Over 18 months, the biomass of native prey fishes increased an average 50-70% on reefs where lionfish numbers were suppressed below target levels predicted to cause prey depletion. On reefs where lionfish numbers remained higher than target levels, the biomass of prey fishes decreased by a further 50%. While complete eradication of lionfish from the Caribbean is not likely, groups are actively removing them from coastal areas (mostly via spear and net). This study is a first step in showing that strategic local efforts that suppress the invasion to low levels can help protect and recover native fish communities affected by lionfish.

Thank you to everyone who has donated during our winter solicitation! If you haven’t already given yet, there is still time to receive my limited-edition, signed print of a Goliath Grouper aggregation by making a contribution. You can find a description at www.REEF.org/impact of how I captured this magical moment. These particular fish in this image are as large as 7 feet and weigh over 500 lbs!
Even today, REEF data are being used to protect this iconic species. In January, an article in Fisheries Research was published to address pressures to reverse the harvest ban on Goliath Grouper (see earlier article). This highlights the importance of your donation in ensuring critical conservation protections stay in place.
7/7/07 marked a successful GAFC Kickoff Party here at the REEF Headquarters, while across the country in Seattle, people gathered to celebrate the art, ecology, and culture of Puget Sound at the Puget Soundscape. Environmental groups were welcomed to this event to share each of their unique contributions to conservation. The renowned Foster/White Art Gallery of Seattle arranged an event in the afternoon dedicated to linking the gap between art and nature through “watchable wildlife.” Master Artist, Tony Angell spoke at the event along with our Director of Science, Christy Semmens, who shared information about the Great Annual Fish Count and REEF’s mission . The gallery generously agreed to donate a portion of the proceeds from the event to REEF.
So far, over half of the registered events have already been completed, and we are eager to hear back of their success. We would like to extend great thanks to all of the coordinators, and best wishes to those coordinators whose events are coming up very soon. Events and their locations still to come include:
California: Discount Dive Trips for the entire month of July hosted by Paradise Dive Club, Santa Barbara, CA
US Northeast/New England: Fish Count Dives onJuly 28th conducted by the New England Aquarium Dive Club, Gloucester, MA;
Caribbean and Bahamas: Weekly multimedia fish ID classes held at CoCo View Resort, Roatan, Honduras through August 4th.
For all of you Great Annual Fish Fanatics who have participated in fish seminars across the country, thank you for your support and don’t forget that you can complete fish survey dives anytime!
A few reminders to our surveyors:
A couple of months ago, REEF launched our new website. Along with the new website, REEF launched some new membership Discussion Forums that will become more valuable as the survey season ramps up this spring/summer. There are 3 forums: ID Central for posting mystery fish and invert pics for other members to help identify and to post interesting fish behavioral observations; Trip Reports, where members can post trip reports for Field Surveys, Exotic Species, AAT, and any REEF or other group efforts; and the General Discussion forum where you can post stories and links about marine conservation concerns, ideas for REEF programs, and myriad other things. These forums are for our 35,000+ members to interact and create a synergistic connection around our conservation diving and snorkel efforts worldwide. Below is a post from long-time member, Todd Fulks, who recently witnessed Hairy Blenny (Labrisomus nuchipinnis) courtship/mating and took a really great picture of the mating pair. I have pasted it here so you can get an example of what could be posted in the ID Central Forum. To post to the forums you have to be a registered REEF.org website user which you can do easily from our homepage in the top left corner under the heading, "Register for an account on our new site." Once registered, you can visit our forums by going up to the menu bar at the top of the homepage and moving your cursor over the Resources option, then clicking on Discussion Forums which is the second item down.
Dive Encounter by Todd Fulks -
"There I was at the end of our dive in just a few inches of water near shore, when I noticed a brilliant bright green fish with red hues on its lower jaw and streaking down its belly. It was sitting near a textbook example of a hairy blenny. I’d been told the males can have brilliant colors when mating so I knew I’d stumbled upon something interesting. As I looked around, I found two more drab olive green females. The girls were just blah-looking in comparison to the clownish colorations of the male hairy blenny. I lurched in the surf a bit as I watched a female slip up against a rock next to the brightly colored male. She jittered and shook violently. Then the male convulsed a few times and shook his body as he finned the underside of the rock. The female flitted a few feet away and the male convulsed again and then jolted to a new perch. The surge was such that I wasn’t able to look under the rock without causing damage so I’m not sure exactly what I witnessed. I’ll have to defer to the experts. Perhaps this was a courtship dance, perhaps they were actually breeding, or maybe egg care by proud parents. Or it could have been something else entirely… I mean it is Carnival time here in Bonaire and I’ve seen some guys wearing strange colorful costumes recently. None of the blennies left the two foot area the entire time and I was able to show all of them to two giddy divers that barely had room on their slates for the 100+ species we saw on the dive. I was determined to catch a good photo of the male, but it was tricky. He was more elusive and shy than the females and moved around frequently. Finally he settled between some rocks and one of his partners nuzzled in close and they posed. ‘Click.’"

Coming Soon -- Online Data Entry For the Northeast and Tropical Eastern PacificFollowing the successful expansion of our Online Data Entry interface for surveys in Hawaii and the Pacific West Coast regions last year, REEF is currently adding the capability for the Northeast (Virginia - Newfoundland) and the Tropical Eastern Pacific (Baja - Galapagos Islands). We hope that this will facilitate an increase in surveying in these important regions. To log your data online, visit http://www.reef.org/dataentry/login.php.
Following the most recent Indo-Pacific Lionfish expedition at Stuart Cove’s in Nassau, Bahamas, we kicked off the next phase of our critical research on this invasive species in Eleuthera. Supporters, Trish and David Ferguson, served as hosts for the week. Earlier this summer, REEF staff set up 11 study sites, tagging 30 fish on six different patch reef and clearing the other 5 sites of lionfish. This past week, I revisited those tagging sites and documented any movement of lionfish. We then following up with early morning, mid-day and evening activity observations to see what the fish were up to and when. The observations involved pre-sun up dives and 2-3 hour bottom times. With some very early and late dive times, the data collected is showing interesting patterns of low light activity.
After five days of intense data collecting at the Ferguson’s we headed down to Cape Eleuthera to meet with staff and students at the Island School and Cape Eleuthera Institute(CEI). The facility is completely self contained, producing their own electricity via solar and wind, their own biodiesel, raising cobia and tilapia in an aquaculture facility and even growing their own hydroponic vegetables. A very impressive operation and an incredible group of staff and students. We were able to conduct collecting and dissecting demonstrations for the coral research class and then do a packed house talk to all of the staff and students from TIS as well as a number from the local Deep Creek Middle School. There is strong interest in collaborating on future lionfish studies as well as incorporating fish surveys into the regular research curriculum at the IS and CEI. Look for future REEF projects to be scheduled here in 2009. Visit our Lionfish Research page for more information.
Last Friday, May 15th, America celebrated Endangered Species Day. While very few marine species have technically been declared as endangered, many of the critters that REEF volunteers see while conducting marine life surveys have experienced declines in recent years. REEF programs and data provide much needed information for scientists and resource agencies charged with evaluating the status of such species. A recent example is a National Marine Fisheries Service (NMFS) proposal to list 5 species of rockfish in the Puget Sound under the Endangered Species Act (ESA). The status review was just published on April 22 and REEF data were extensively used in the assessment. This example highlights the value of REEF data as a fisheries-independent data source; such information is critical for those species that are too rare to be targeted for harvest. A copy of the assessment is posted online.
The Nassau grouper, which is the focal species of REEF’s Grouper Moon Project, has been classified as endangered under the IUCN’s Red List. The Grouper Moon Project is a collaborative conservation program between REEF and the Cayman Islands Department of the Environment to study one of the last known large Nassau grouper spawning aggregations in the Caribbean. Grouper Moon Project lead scientist, Dr. Brice Semmens, will be presenting the ground-breaking findings of this research during a special one day session to be held in the Ocean Hall at the Smithsonian’s National Museum of Natural History this Wednesday, May 20th. "Beyond the Obituaries: Success Stories in Ocean Conservation" will feature some of the good news coming out of work being conducted in the oceans. Brice’s talk, along with all of the success stories, will be webcast online. The Grouper Moon talk is scheduled in the Coral Reef session, which is from 2-3:25.
