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.

Connecting With Classrooms in the Grouper Moon Project

In collaboration with a team of engineers from Scripps Institution of Oceanography we are using a cutting-edge underwater microscope with plankton net attached to study the habitat around the spawn cloud. As water flows through, two high speed cameras within an underwater microscope capture images of zooplankton and eggs.

Scientists and volunteers from REEF, and our partners at Scripps Institution of Oceanography and Cayman Islands Department of the Environment, are wrapping up two weeks of field work on Little Cayman for the Grouper Moon Project. Since 2002, the collaboration has conducted ground-breaking research on the Nassau Grouper spawning aggregations in the Cayman Islands, to help ensure that populations of this iconic species recover. Around winter full moons, Nassau Grouper leave their home reefs and aggregate in mass to spawn. January didn't turn out to be the big month for spawning, and therefore our team will return for the February full moon. Nevertheless, many of the fish (at least 1,000) showed up at the aggregation site and our team kept busy collecting ongoing monitoring data (counts, size of fish, and documenting behaviors), field testing cutting-edge tools such as an underwater microscope, and running the Grouper Education Program.

In 2011, with funding from Disney Conservation Fund, REEF launched the Grouper Education Program to engage Caymanian students in the Grouper Moon Project. This exciting effort brings the Nassau Grouper in to elementary and high school classrooms through lesson plans and live-feed videos that connect classrooms with scientists in the field. The curriculum presents a multi-faceted view of Nassau Grouper in which students create their own understanding of this important fish. Key curricular concepts include the historical role of the species as an artisanal fishery throughout the Caribbean region, the grouper’s value as a keystone predator and its impact on local reef health, its role in today’s tourism-based economy in the Cayman Islands, and the conservation challenges facing Nassau Grouper given steep declines in populations. 

In January, we conducted four live-feed webcasts - three topside chats with scientists and one from underwater at a coral reef site along Bloody Bay Wall. All webcasts are archived on YouTube on TheGrouperTeacherREEF channel online here. Over 200 students from 17 schools participated.

Several interesting video clips and stories from the field were posted on REEF's Facebook page.

The work of the Grouper Moon research project – a collaboration between REEF and the Cayman Island Department of Environment has led to fishing restrictions at the aggregation sites and an increase in numbers of the endangered fish. To find out more, visit www.REEF.org/groupermoonproject. The Grouper Education Program is supported by a grant from the Disney Conservation Fund.

“Finding Dory” and Promoting Responsible Pet Ownership

The highly-anticipated sequel to Disney and Pixar’s “Finding Nemo”, “Finding Dory” opened in theaters in June, and was recently announced to be the highest-grossing animated film of all time. The titular character, Dory, is a Palette Surgeonfish (Paracanthurus hepatic), who spends the film searching for her family. Native to the tropical waters of the Western Pacific Ocean (REEF’s Central Indo-Pacific and South Pacific regions), these bright blue, reef-dwelling, algae-eating fish are also referred to as Pacific Blue Tangs, Hippo Tangs, or Regal Tangs. In addition to the film’s endearing characters and entertainment value, the release of “Finding Dory” carries the potential for an increased demand for Palette Surgeonfish in home aquariums, as well as the message that marine fish should be released into the wild.

Marine biologists worry that the release of “Finding Dory” could cause an increased demand for Palette Surgeonfish, threatening wild populations as well as coral reef habitats. National Geographic estimates that following the release of “Finding Nemo” in 2003, the demand for Clown Anenomefish (Amphiprion percula) like Nemo, more than tripled. Anenomefish are able to be aquacultured, or bred in captivity. Until recently, Palette Surgeonfish had never successfully been captive-bred, however, researchers at the University of Florida Tropical Aquaculture Laboratory recently announced that for the first time they have successfully raised the Palette Surgeonfish in captivity. This conservation breakthrough means that aquarists may soon have a source for Palette Surgeonfish that does not rely on fish removed from the wild. REEF encourages pet owners to educate themselves about fish ownership before buying a marine fish, including specifics on living requirements such as tank size, and whether the fish was bred in captivity or caught in the wild.

In addition, pet owners should have a plan in place in case they are ever unable to care for their fish. In “Finding Dory”, we learn that Dory was born and raised in a facility on the California coast, but eventually ended up in the wild. Releasing non-native marine fish into the ocean from home aquariums, while well-intentioned, can create severe problems for marine ecosystems. One threat includes the spread of invasive species, like the Indo-Pacific Lionfish, which has caused dramatic impacts since their initial introduction in the 1980’s. Non-native fish may also carry diseases and parasites that can have harmful impacts on native fish species.

In 2015, REEF launched the “Don’t Release Me” campaign to educate pet owners about responsible pet ownership, teach the public about the effects of releasing non-native pet species into the wild, and work cooperatively with other organizations to promote alternatives to pet release and stop the spread of invasive species.

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 United States Geological Service (USGS), the National Aquarium in Washington DC, the Bahamian Government and university groups, has spearheaded the field research for this rapidly expanding problem. As part of REEF’s Lionfish Research Program, over the last two years REEF has coordinated 12 research projects that have involved over 175 REEF volunteers. This research has generated a wealth of in-situ observations and over 1,000 lionfish specimens, which have led to great advances in the understanding of the biology and potential impacts of this most unwanted invader.

REEF’s 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.  Findings included:

Lionfish continue to grow in size: Tagging data show growth rates exceeding 190mm/year, far larger than necessary to reach sexual maturity.

Site Fidelity: All 12 previously-tagged specimens that have been recaptured indicate strong site fidelity even after 6 months.

Prey: Lionfish continue to amaze us during stomach content studies. The recent 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. Lionfishare eating nearly anything that will fit into their mouths.

Reproduction: Lionfish reproduction occurs throughout the year – many gravid females and a small recently settled juveniles have been found.

REEF’s future fieldwork 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.
