REEF’s 2016 REEF Trips schedule is well underway! Two trips have already happened (Dominica and Barbados), and a group of eager fishwatchers is heading to the Philippines in a few days for our inaugural Field Survey to the Indo-Pacific. Be sure to check out the Trips schedule at www.REEF.org/trips, if you haven’t already. In addition to the traditional fish identification and surveying trips, we also host several Lionfish Study Trips each year. There are still a few spaces left on lionfish trips to Honduras in May and Curacao in August, and we are looking for team members. These important projects provide valuable data, and result in the removal of hundreds of the invading fish during the week.
During the week-long projects, either liveaboard or land based, team members are presented with training and opportunities to remove lionfish through spearing or hand netting. All collected lionfish are measured and some dissected on site to get valuable biological and impact information and some fish are prepared for team and public tastings to help promote the market for lionfish as a food fish. Team members can get fully immersed in as much of the collecting and research activities as they would like. Divers not wanting to take part in removals, still provide valuable sighting information and conduct REEF fish surveys to augment the long-term data used to look at ecological changes.
One example of Lionfish Study Trip data includes a series of annual projects we held in Belize between 2009 and 2012 that documented the progression of the invasion. From zero fish seen or collected during the first year of the project, to over 500 fish removed in a single week during year three, divers were able to document the incredible explosion in numbers but also dramatic increases in sizes. Average size of lionfish collected in 2010 was 194mm, exploding to 270mm in 2012. Another example was from our lionfish recent trip to Dominica in February. This was our second lionfish trip there. In 2012, our team collected 45 lionfish. This year, in the same locations, the team collected 566. Click here to see other examples of findings from Lionfish Study Trips.
And keep an eye on your inbox because we will be sending out the full 2017 REEF Trips schedule next week!
Earlier this month, REEF Director of Science, Dr. Christy Pattengill-Semmens, participated in the first of a series of workshops to be held this Fall to analyze REEF and other data gathered from the Channel Islands Marine Protected Areas (MPAs). Originally established in 2003 (and then expanded to include Federal waters earlier this year), this network of no-take marine reserves protects 318 square miles around the northern five Channel Islands off the coast of California. In 2008, the California Fish and Game Commission will conduct a 5-year review of the MPAs to evaluate the effectiveness of the reserve network. The results from the evaluation will inform future decisions made by the Commission under California's Marine Life Protection Act. The data group workshops, held at the National Center for Ecological Analysis and Synthesis, will culminate in a series of publications summarizing the cumulative efforts of dozens of monitoring programs within the Channel Islands MPAs, with an emphasis on analyses that can best address key management questions concerning the reserves. These results will be presented during a special symposium associated with the California Islands Symposium.
Coincident with the establishment of the marine reserves in 2003, REEF initiated a coordinated monitoring program at specific sites inside and outside of the reserves to complement the ongoing survey activities in the area by REEF members. Surveyors on REEF's Pacific Advanced Assessment Team participate in annual REEF cruises aboard the Channel Islands National Marine Sanctuary (CINMS) vessel R/V Shearwater, and this project has generated over 800 surveys to date. These data, along with an additional 750 REEF surveys that had been conducted around the islands prior to 2003, will provide information on the fish assemblages (and more recently key invertebrate and algae species) of the Channel Islands.

On Tuesday, February 26 and Wednesday, March 12, REEF hosted two citizen science panel discussions about how volunteers contribute to understanding and preserving the Florida Keys environment. The first discussion, held in Key Largo, featured speakers from the Breeding Bird Survey project, Coral Restoration Foundation, and John Pennekamp State Park native plant nursery. The second event, held in Key West, featured speakers from The Nature Conservancy, Mote Marine Laboratory and the National Weather Service. Both discussions were led by guest speaker Rick Bonney, a pioneer in the citizen science field from the Cornell Lab of Ornithology in Ithaca, NY. Leda Cunningham presented on the REEF Volunteer Survey Project.
Forty-two people participated in the discussions, most of whom were themselves volunteers in a local or national citizen science project. "Most scientists usually only get to attend 'niche' meetings, where everyone in the room is talking about variations of the same subject matter," said Alison Higgins of The Nature Conservancy. "What was amazing about REEF's Citizen Science symposium is that the approach was the same (engaging the public in collecting important observations), but the subjects were varied. I specialize in land conservation issues, but got to brainstorm and engage with fish, bird and weather scientists - It was a really great and necessary experience"
Each discussion group brainstormed next steps for the citizen science movement in the Florida Keys. Ideas included forming an informal coalition of citizen science projects, doing integrated data analysis across project taxa (effect of weather on fish or bird population trends, e.g.), starting a regular citizen science column in a local newspaper and developing a citizen science booklet for residents and visitors to learn about local projects. For more information, please contact Leda Cunningham: Leda@REEF.org.
In addition to attending the 11th ICRS, REEF also hosted one of the conference Field Trips. REEF and Horizon Divers hosted 14 participants from various locations around the world including Australia, Japan, Kenya, and several U.S. institutions. Dr. Jim Bohnsack, NOAA Research Fisheries Biologist and Science Advisor to the REEF Board of Trustees, gave a workshop presentation on applying REEF fish survey data towards Florida Keys National Marine Sanctuary management decisions and Paul Humann, renowned marine life photographer and author, taught fish and invertebrate identification classes. Lad Akins, REEF Special Projects Director, gave an overview of REEF and our programs along with a detailed update on what he and REEF partners are working on with the Lionfish (Pterois volitans) invasion in Florida, the Bahamas and Caribbean islands. Participants also had the opportunity to conduct 6 REEF survey SCUBA dives out on our local reefs to get a sense of how Roving Diver survey data are collected.
The survey data our members collect fall into two general categories.The first is the Volunteer Survey Project category that includes all of our Field Surveys and individual members surveying efforts conducted while diving or snorkeling wherever they live or travel to on vacation. The second type of data collected by our surveyors are from our monitoring and research programs in partnership with NOAA sanctuaries, the National Park service, and regional NGO’s and other non-profits as well as various universities. It was this second category of data that our ICRS Field Trip focused on for classroom discussions. REEF data are used by resource managers include artificial reef monitoring, restoration site monitoring, marine protected area assessments, and invasive species collections and fish surveys to name a few. One message that ICRS brought home to all attendees is that now more than ever, there is a critical need for coral reef related research, including studies addressing fish assemblages. There is also a critical need for scientists and policy makers to communicate their research and conservation strategies to the general public, conveying the message about just how vulnerable coral reefs are to anthropogenic disturbances and their importance to our collective well being. REEF will continue our efforts to engage our membership in worthwhile conservation projects that address tropical and temperate fish assemblages.

Check out the latest news in the lionfish invasion. - There's so much going on with REEF's lionfish research and outreach programs, we can't possibly report it all here. Check out the Lionfish in the Media page to see how the media is covering our efforts.
Online data entry available in all regions. - As we reported in last month's REEF-in-Brief, REEF surveyors in ALL regions can now submit their data online. We greatly encourage everyone to enter their surveys online rather than use the paper scanforms, if possible. And remember -- if you conduct a survey at a site that is not yet in REEF's Zone Code database, send us an email (firstname.lastname@example.org) with the site name and latitude/longitude of the site and we will create the code for you. The 8-digit zone code must be in the system before you can enter data from the site.
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.
