REEF-in-Brief August 2010

Introduction

Dear Valued REEF Members,

We are pleased to bring you this end-of-summer edition of our e-newsletter, REEF-in-Brief. As always, summer is a busy time at REEF (which is why the "August" newsletter is arriving to you in September!). At REEF HQ in Florida, staff are gearing up for the first lionfish derby series in the Keys. This invasive non-native species is rapidly becoming a common sight throughout the western Atlantic and REEF is at the forefront of the outreach, research, and control efforts. We have also been putting the finishing touches on our 2011 Field Survey schedule. A preview of these trips is below. Watch for more details in the coming weeks. And a new scientific paper was just published that includes an analysis of REEF data on shark populations in the Caribbean. We are excited to announce a unique opportunity to own a pre-release, numbered and signed copy of the highly anticipated Reef Creature Identification - Tropical Pacific ID guide. Pre-release copies #1-#5 have been donated to REEF and we will be auctioning them off through eBay starting this Sunday (September 12). The auction will close on September 22. During this time, you can view the auction and bid on the books here. And finally, REEF's Director of Science, Dr. Christy Pattengill-Semmens, as well as REEF Board of Trustee Heather George and a team of 4 other REEF volunteers, just returned from American Samoa to mark the official launch of REEF's Fish Survey Project in the South Pacific. A full report about this trip and the new program will be included in the next newsletter.

Tropical Pacific Critter ID Book, Pre-Release Special Edition 10 Day Auction on eBay

TP_CR_cover_sm.jpg

After years of work, the Tropical Pacific edition of Reef Creature Identification by Paul Humann and Ned DeLoach is being released later this fall. A limited number of pre-release, signed and numbered copies will be available beginning Monday September 13. The authors have donated to REEF the first five pre-release copies of this spectacular book. REEF will be auctioning copies #1-#5 through eBay. The copies will be numbered, signed, and personalized to the winner's specifications. All proceeds from this auction will go directly to REEF, and will support our critical marine conservation programs. The auction goes live Sunday September 12 at 9pm EST. Once live, you can find the auction pages for all five copies here. The auction will last 10 days.

The long-awaited, 500-page reference detailing 1,600 animals with 2,000 photographs and descriptive text is not only the most comprehensive visual field guide to marine invertebrate life inhabiting the waters from Thailand to Tahiti, but also a pictorial tour de force skillfully bridging science and the aesthetic. For the past five years the two authors/photographers have delved deep into uncharted waters, not only visually documenting numerous species for the first time, but also incorporating the most recent taxonomic research of more than 40 scientific specialists. The text focuses on mobile species, highlighting crustaceans, mollusks, worms and echinoderms, however the pages include an overview of attached marine animals, and also explore facets of marine invertebrate behavior. The guide provides a boon of information for diving photographers and underwater naturalists, known as critter hunters, who enjoy one of the most challenging games in the sea – searching for charismatic mini-fauna of the reef. And for the armchair adventurers, the brilliant gallery of images brings an unseen, unimagined world to the surface like never before.

    Reef Environmental Education Foundation (REEF) with help from the Florida Keys National Marine Sanctuary (FKNMS) will host an inaugural series of lionfish derbies in the Keys starting this weekend. Divers who remove lionfish from Sanctuary waters will be eligible for more than $10,000 in cash and prizes. Awards will go to the top 3 teams in the following categories: most lionfish, biggest lionfish, and smallest lionfish.

    REEF and Sanctuary managers have been working with the Florida Keys dive community to remove invasive lionfish since early 2009. Scientists are concerned about the rapid population growth of lionfish in Keys waters and their lack of a natural predator in the Atlantic. Lionfish are known to feed on ecologically and commercially important fish species — including snapper, grouper and shrimp — and can disrupt the balance of the marine ecosystem.

    “Current research is beginning to show that, if left unchecked, the impacts of lionfish could be devastating to our native marine life and coral reefs,” said Lad Akins, REEF Director of Operations. “Providing training and incentives for the public to remove lionfish is one way to control populations and minimize those impacts.” Following detailed briefings by REEF staff on lionfish collecting and handling, divers will be allowed to collect fish on the day of the tournament using hand nets or spearfishing gear in areas of the sanctuary where fishing and spearfishing is allowed. A new rule was just passed July 27th, 2010 that enables divers to collect lionfish with hand nets throughout Pennekamp State Park in Key Largo.

    The $100 derby registration fee for a four-person team of divers or snorkelers provides participants with a pair of puncture resistant gloves and banquet tickets. Event banquets will feature a lionfish tasting for derby participants and guests. These derbies are not only a great way to reduce local lionfish populations, but also serve to educate and engage the public in lionfish control efforts.

    “Eating lionfish is a conservation activity,” said Sean Morton, acting FKNMS Superintendent. “We are its only known predator in the Atlantic and through dedicated diver-based removal efforts, and consumption of lionfish as a food source, we can control its establishment.” NOAA has even developed an “Eat Lionfish” campaign that brings together fishing communities, wholesalers, and chefs in an effort to broaden U.S. consumers’ awareness of this delicious invader.

    For more information on REEF's lionfish research program, the derbies, and to register online, visit www.reef.org/lionfish. Dates and locations for the derbies are: September 11 – Coconuts Restaurant, Key Largo • October 16 – Keys Fisheries Market and Marina, Marathon • November 13 — Hurricane Hole Marina, Key West. Florida Keys lionfish derbies are sponsored in part by: Ocean Reef Conservation Association, Divers Direct, Spree Expeditions, Inc., Dive Key West, Inc., and Scuba-Do Dive Company. To become an event sponsor, please contact Alecia@reef.org. REEF-coordinated lionfish derbies in the Bahamas have removed almost 2,500 lionfish since 2009. Thousands more fish have been captured in more than 30 REEF-organized lionfish collection trips across the Caribbean. Because of REEF’s vast experience with lionfish control programs, the Florida Keys Lionfish Derbies are destined for success!

    REEF Data Featured in New Scientific Publication on Shark Population Status

    REEF Fish Survey Project data were recently featured in a paper in the scientific journal PLoS ONE, Large-Scale Absence of Sharks on Reefs in the Greater-Caribbean: A Footprint of Human Pressures. The study's authors evaluated the status of 14 species of sharks in the Caribbean. In recent decades, large pelagic and coastal shark populations have declined dramatically with increased fishing. However, the status of sharks in other systems such as coral reefs remains largely unassessed despite a long history of exploitation. The paper's authors used REEF data to explore the contemporary distribution and sighting frequency of sharks on reefs in the greater-Caribbean, and assessed the possible role of human pressures on observed patterns.

    The analysis was based on 76,340 underwater surveys carried out by REEF volunteers between 1993 and 2008. REEF data are well suited for rarely seen species like sharks because of the wide geographic coverage by REEF volunteers.The authors compared sighting frequency to the number of people in each area surveyed, and used population viability analyses to assess the effects of exploitation on population trends. Sharks, with the exception of nurse sharks, occurred mainly in areas with very low human population or strong fishing regulations and marine conservation. Population viability analysis suggests that exploitation alone could explain the large-scale absence; however, this pattern is likely to be exacerbated by additional anthropogenic stressors, such as pollution and habitat degradation, that also correlate with human population. Preventing further loss of sharks requires urgent management measures to curb fishing mortality and to mitigate other anthropogenic stressors to protect sites where sharks still exist. The fact that sharks still occur in some densely populated areas where strong fishing regulations are in place indicates the possibility of success and encourages the implementation of conservation measures.
