Despite uncertainties surrounding the population status of the protected Atlantic Goliath Grouper’s, fishery managers in Florida are under pressure to end the harvest moratorium in place since 1990. A new study published this month in the scientific journal, Fisheries Research, sought to measure the proportion of anglers interested in reopening the Goliath Grouper fishery and to identify key reasons for this interest. The authors also estimated the amount that anglers would be willing to pay for a Goliath Grouper harvest tag (the right sold to an angler to harvest one Goliath Grouper). REEF data on Goliath Grouper were used to compare with the fishermen-perceived grouper population trends. REEF data have been cited as the best available index of abundance for Goliath Grouper in Florida (see Koenig et al., 2011, www.REEF.org/db/publications/9754). The study found that about half of Florida’s recreational anglers believe that the ban on fishing for Goliath Grouper should be lifted, with many anglers reporting that they feel "there are too many goliath grouper and that their populations need to be controlled." These anglers are willing to pay between $34 and $79 for the right to harvest one Goliath Grouper in Florida.

As fishery managers work to determine the future of Goliath Grouper in Florida and the rest of the southeast United States, this study's findings can help them better understand stakeholder intentions and better communicate to the public. Additionally, fishery managers can compare the amount of money recreational anglers are willing to pay to open the fishery to the amount of money other stakeholders, such as recreational divers who visit goliath grouper, are willing to pay to keep the fishery closed. The new paper is titled "Lifting the goliath grouper harvest ban: Angler perspectives and willingness to pay", and was published by Geoffrey Shideler, a scientist at Rosenstiel School of Marine and Atmospheric Science University of Miami, and colleagues from NOAA Fisheries.

Remembering Joe Thomas

Joe Thomas at the helm of his boat.

On August 24, 2015, a beloved member of our Key Largo community unexpectedly passed away. Joe Thomas of Ocean Divers was a brilliant captain, a caring mentor, and a wonderful friend, known for his softspoken demeanor and sharp sense of humor. Joe loved to share his passion for the sea, whether it was through educating young divers or imparting his knowledge of the local dive sites and Key Largo history to the many who looked up to him. Joe was a member of the REEF family for more than 20 years. He selflessly dedicated his time to helping many generations of Marine Conservation Interns advance their diving skills by offering training and certifications for courses such as Nitrox, Advanced Open Water, and Rescue Diver. Joe also provided support for and participated in numerous REEF monitoring and research projects throughout the Florida Keys. He was a valued member of REEF's Advanced Assessment Team and made a significant contribution to citizen science by submitting more than 500 fish surveys. He will be greatly missed.

At the request of Joe's close friends throughout the Key Largo community, The Joe Thomas Memorial Fund has been created as a legacy to remember the ideals by which Joe lived and worked, and to support educating future generations of marine conservationists and divers to protect the ocean that Joe loved so much. Proceeds from the fund will be used to aid young people beginning careers in marine conservation and diving by providing intern scholarships and dive certifications. To contribute to the fund, click here to donate securely online. Be sure to type "Joe Thomas" in the comment section on the donation page. You can also make a donation over the phone by calling REEF at 305-852-0030, or by sending a check to REEF HQ, PO Box 370246, Key Largo, FL 33037.

A celebration of life will be held in Key Largo later this month. If you have a memory of Joe to share, please visit www.REEF.org/joethomas.

The second edition of The Lionfish Cookbook is available on REEF's website.

On June 22, SCUBA divers, marine conservation enthusiasts, and foodies gathered at Piccolo Ristorante in Fort Lauderdale, Florida, to attend the second annual Lionfish Tasting Dinner. During the event, patrons learned about effects of the lionfish invasion while sampling the tasty invader’s light, white meat. At the end of the evening, DiveBar, one of the night’s sponsors, presented REEF with a check for $1,500 to support our Invasive Lionfish Program.

The night’s menu featured invasive lionfish, known for their voracious appetites and rapid reproduction. Each lionfish dish incorporated unique ingredients and creative preparations, beginning with a smoked fish dip appetizer, followed by four tapas-style courses, including a lionfish corn dog, surf and turf lionfish yucca croquette with marinated skirt steak, blackened lionfish taco with tropical salsa, and finally, an IPA beer-battered lionfish over rice. Each course was paired with a wine to complement the individual dish’s distinctive flavors.

Between courses, REEF Trips Program Manager Amy Lee gave a presentation to educate attendees about the lionfish invasion and the importance of lionfish removals. At the end of the night, Andres Avayú, chef at Piccolo Ristorante, demonstrated how to safely handle and fillet a lionfish. REEF’s second edition of “The Lionfish Cookbook”, published in February, features Chef Andres’ own unique recipe, lionfish with zucchini potato pancake and roasted red pepper coulis, as well as more than 60 lionfish recipes from many other chefs throughout the invaded region.

Red Lionfish, native to the Indo-Pacific and Red Sea, have invaded the Western Atlantic Ocean, Caribbean, and Gulf of Mexico. Lionfish diets are very broad and include both fish and crustaceans. They have been documented to consume more than 120 species of prey, including commercially, recreationally, and ecologically important species. “It’s exciting to see such strong public and commercial interest in consuming lionfish,” says Lad Akins, REEF Director of Special Projects. “Developing a market for lionfish is a great way to provide incentive for increased removals. Even non-divers can make a real impact, by ordering the fish at their local restaurants, helping to decrease lionfish populations and minimize their impacts.”

Sponsors of the Lionfish Tasting Dinner include DiveBar, Miami Wine Buzz Club, Jack Scalisi Wholesale Fruit and Produce, and 8 Shades of Blue. All lionfish fillets used at the event were donated by Sean Meadows of World of Scuba, who recently hosted a REEF Sanctioned Lionfish Derby in Boynton Beach, Florida. Thanks to the joint efforts of these supporters and Piccolo Ristorante, the Lionfish Tasting Dinner raised $1,500 to support REEF’s marine conservation programs!

REEF hopes to organize more Lionfish Dinners to continue spreading awareness of the lionfish invasion and encouraging the public to consume this malicious yet delicious invader.

Putting it to Work: New Publication Showing Link Between Land Impacts and Fish Populations

Figure 4a from Roberts et al 2017 paper in "Ocean & Coastal Management", showing a topographic map of Bonaire.

We are proud to share details on a recent scientific paper published using REEF data - "Terrestrial degradation impacts on coral reef health: Evidence from the Caribbean" by M. Roberts et al. This was the 7th scientific paper using REEF Volunteer Fish Survey Project data or other REEF projects published in 2017.

In this paper, published in the journal Ocean & Coastal Management, REEF fish survey data collected from Bonaire in 2015 were used to help evaluate the impact of terrestrial degradation on nearby coral reefs, specifically investigating the link between vegetation ground cover and tree biomass index to coral cover, fish communities, and visibility. The authors found a positive relationship between ground cover and coral cover below 10 m depth, and a negative relationship between tree biomass index and coral cover below 10 m. Greater ground cover is associated with sediment anchored through root systems, and higher surface complexity, slowing water flow, which would otherwise transport sediment. The negative relationship between tree biomass index and coral cover is unexpected, and may be a result of the deep roots associated with dry-forest trees, due to limited availability of water, which therefore do not anchor surface sediment, or contribute to surface complexity. The analysis provides evidence that coral reef managers could improve reef health through engaging in terrestrial ecosystem protection, for example by taking steps to reduce grazing pressures, or in restoring degraded forest ecosystems.

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.

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.’"
