Putting It To Work: New Publication on Efforts to Control Invsive Lionfish

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.

Adding to Your Life List - Horned Blenny!

One of the most rewarding and fun aspects of being a REEF surveyor is finding a new species to add to your "Life List" (a lifetime compilation of all fish species seen). Even the most experienced surveyors, after hundreds of surveys, occasionally add new species to this list. Expert Caribbean surveyor, Patti Chandler, recently emailed us about one such find. Despite having over 900 REEF surveys under her (weight) belt, she and her husband Scott recently came across a little mystery while diving in front of CocoView Resort on Roatan - a brilliant blenny with BIG cirri on its head. After emailing the photo to a few experts, they discovered that they had captured what is likely the first in situ photos of the species, and also documented the first record of the species in the Western Caribbean. Not only does their sighting of a Horned Blenny (Paraclinus grandicomis) represent a "lifer" for their lists, it was also a new record for the TWA REEF database. Great find, Patti and Scott!

If you have a First Sighting story to share, email us at data@REEF.org. And did you know? - If you are a REEF surveyor, your Life List can be accessed under the 'My REEF' menu when you are logged in to the REEF website.

WASH Nearshore Symposium

REEF’s Director of Science, Dr. Christy Pattengill-Semmens, was an
invited speaker at the Temperate Reef Resources Symposium held at the University of Washington in early June. Christy spoke on the role that volunteers play in generating needed data for managing temperate reefs, and used examples from REEF experiences and projects in three west coast National Marine Sanctuaries, the Olympic Coast, Monterey Bay, and
the Channel Islands. To date, over 10,000 REEF surveys have been conducted in coastal areas along the west coast of the US and Canada.

Channel Islands Shore to Sea Lecture Series

 
In early July, Christy was the featured speaker for the monthly Channel Islands Shore to Sea Lecture Series, which is sponsored by the Channel Islands National Marine Sanctuary and Park. Christy spoke on REEF surveying inside and outside of the marine reserve network that was
implemented around the Channel Islands in 2004. Much of these data are
collected using REEF’s Pacific Advanced Assessment Team aboard the Channel Islands National Marine Sanctuary’s Research Vessel Shearwater.

Flower Garden Banks National Marine
Sanctuary fisheries impact workshop

Christy also presented information on the REEF
Volunteer Survey Program at a recent priority issues workshop on fishing impacts for the Flower Garden Banks National Marine Sanctuary. The workshop was used to discuss the possibility of Flower Gardens National Marine Sanctuary implementing experimental no-take zones within the Sanctuary. Christy presented information about REEF's volunteers 14 year long monitoring of reef fish at the Flower Garden Banks National Marine Sanctuary, and how this data can provide a valuable baseline to be able to measure the effects of any future no-take zones that might be implemented in the Sanctuary.

Once again, CEDAM International is offering two scholarships for educators to participate on a REEF Field Survey. For the 2008 survey season, the scholarships will apply to the Gran Bahia Principe Field Survey in Akumal, Mexico. Dates for this trip are May 17-24, 2008. You can visit REEF's Field Survey page to view trip details and also check out the trip flyer. To apply for this scholarship, please visit the CEDAM website at then click on the Lloyd Bridges Scholarship tab at the top of the page to see details.

The two scholarships enable qualified educators to participate - at no cost - in a CEDAM-sponsored or -sanctioned expedition. This REEF Field Survey will be led by Joe Cavanaugh, REEF Field Operations Director. Participants will have the opportunity to collect data, participate in daily talks, and interact with REEF members, staff, and local organizations. This will be a hands-on experience during which participants have the opportunity for fish identification and marine conservation training in and out of the water. REEF has partnered with ReefAid and Reefcheck and Ecologica Bahia in 2007 to assist Gran Bahia Principe Resort with developing a monitoring and assessment protection plan for their nearshore reefs. Our cooperative efforts in conservation at Bahia Principe are making a difference in protecting their reefs and some of our class time will focus on these successes.

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.The scholarship will be awarded on the basis of both merit and financial need. CEDAM International will cover the recipient’s airfare and REEF Field Survey expenses (excluding incidentals and personal expenses), on this educational adventure. Bahia Principe is an all-inclusive resort so acoomodation, diving, and meals are included. The application deadline will be earlier than last year's deadline since the Field Survey pariticipation dates are in late May this year. Please have your completed applications submitted by April 1, 2008.

Many of our members may be too young to have seen the television program, Sea Hunt, starring Lloyd Bridges that ran from 1958-1961. One important aspect of the series was that Bridges made a plea at the end of each episode to protect the oceans, an early ocean conservation pioneer. He was also involved in several organizations including the American Oceans Campaign and Heal the Bay, a Los Angeles-based conservation group. He inspired a generation of SCUBA divers and you may want to check out Wikipedia to read more about many of the people Bridges worked with on Sea Hunt. Incidentally, I discovered that Bridges learned to SCUBA dive once contracted for the show and that he was offered the role of Captain Kirk before William Shatner!

There are still spaces (4) available for the Akumal Field Survey, email joe@reef.org to inquire.

All applicants must complete an application form and return it along with the required essay and two letters of recommendation, to CEDAM (by mail or electronically) by April 1, 2008. Good Luck!

Bigger Than Ever - Lionfish Research Continues

As many of you are aware, the recent invasion of Indo-Pacific lionfish into Atlantic waters has been causing great concern among researchers, marine park and fisheries managers, and divers. REEF, in partnership with Bahamian dive operators Stuart Cove and Bruce Purdy, NOAA, the USGS, the National Aquarium in Washington DC, the Bahamian Government and university groups, has spearheaded the field research for this rapidly expanding problem. 

 

Our most recent field project at Stuart Cove’s Dive Bahamas in May 2008, involving over 20 volunteers and researchers, found that the problem continues to get worse. The team gathered data on nearly 200 specimens of lionfish to determine relative abundance, size increases, reproductive status, growth rates, predator prey relationships and movement.  To wit:

 

  • Lionfish continue to grow in size: Tagging data are showing growth rates exceeding 190mm/year.  This is far larger than necessary to reach sexual maturity.
  • Site Fidelity: All 12 tagged specimens that have been recaptured indicated strong site fidelity even after 6 months.
  • Prey: Lionfish continue to amaze us during our stomach content studies. This May effort turned up new records including two entire spotted goatfish, a large brown chromis, a small reef octopus, and even a small mollusk in its shell. The lionfish are eating nearly anything that will fit into their mouths.
  • Reproduction: Lionfish reproduction continues to occur throughout the year – we found many gravid females and a small recently settled juvenile.

 

To date, dive operators and the contributions of participating volunteers have funded the bulk of this work.  REEF’s future field-work will concentrate on lionfish movement, trap design, habitat preference, and local control measures. Our next project is scheduled to take place at Stuart Cove’s Dive Bahamas in Nassau from September 14-20. If you would like to help with our ongoing work please consider joining us as a field volunteer and/or making a contribution to REEF’s Exotic Species Program. For additional information, please contact Lad Akins at (305) 852-0030 x-2# or e-mail Lad@reef.org

Taking A Dive Trip That Counts

As Fall is upon us, we look ahead to 2009 and a great lineup of REEF travel opportunities. Our partners at Caradonna Dive Adventure have helped us put together an exciting Field Survey schedule, including St. Croix, Bermuda (with Ned and Anna DeLoach), and Grenada on the Peter Hughes Winddancer (with Paul Humann). These week-long projects are led by experts in fish identification and include great diving, learning, and camaraderie with like-minded divers and snorkelers. Your non-diving companions are welcome on all of the land-based projects. There will also be several Lionfish Research Project expeditions, which allow participants to get first hand experience in this exploding invasive species issue. Be sure to check out all of these trips, posted online at http://www.reef.org/fieldsurveys/schedule. And remember that it's not just on REEF Trips that you can Make Dives That Count! You are encouraged to conduct surveys during your personal dive vacations farther afield and on local weekend dives in your own backyard. Be sure to order survey materials through the REEF Online Store before you leave and check out what species you are likely to see with the Geographic Summary Reports. And while you are waiting for your tank to be filled, it's fun to tell the folks at the dive shop what you are doing. Being a REEF ambassador helps spread the word about the Volunteer Survey Project and the value that fishwatching adds to your experience in the water. We hope that you will join us in making dives that count in 2009. We are kicking off the year with a Field Survey to St. Lucia led by new REEF Executive Director, Lisa Mitchell. To find out more or to book your space, please contact our dedicated travel specialist at 877-295-7333 (REEF), REEF@caradonna.com. And be sure to download our 2009 Trip Flyer!
