REEF data were used to provide a fisheries independant index for use in the mutton snapper stock assessment conducted by the South Atlantic and Gulf of Mexico Fisheries Management Councils as part of the SEDAR process. Three indices were calculated with different subsets of the REEF dive surveys: an index based on all dives on Florida’s Atlantic coast; an index based on sites that were visited by divers on at least seven of the 13 years, i.e. more than half, and at which mutton snapper were observed more than once; an index that used a logistic regression of presence or absence of species on the dives to calculate the probability that a dive would observe mutton snapper.
This publication describes a new (to science) species of coral reef wrasse found by REEF surveyors at the Flower Garden Banks National Marine Sanctuary (FGBNMS). This species was nicknamed the "Mardi Gras wrasse" by sanctuary staff due to the bright purple, yellow and green coloration of the terminal male phase. The fish was originally discovered at the East Flower Garden Bank by members of a REEF survey team in 1997, and has been periodically observed (primarily at Stetson Bank) since that time. Subsequent investigation by Doug Weaver and sanctuary staff confirmed that it was in fact a previously undescribed species of wrasse. The scientific name of the species is Halichoeres burekae, in honor of FGBNMS photographers Frank and Joyce Burek, who obtained the first photograph of the fish. The Mardi Gras wrasse has also since been reported from the Veracruz region of Mexico.
This study analyzed temporal trends of the yellow stingray in the Florida Keys National Marine Sanctuary (FKNMS) as recorded by trained volunteer divers using the Roving Diver Technique. Data were obtained from the REEF Fish Survey Project. A generalized linear model on presence-absence data was used to estimate the change in yellow stingray by year. Habitat type, bottom time, depth, site, water temperature, and Julian date were included in the model to standardize the data. The decline in sighting frequency has occurred in all habitat types, depths, sites, and regions of the FKNMS. Within the FKNMS yellow stingray sightings declined from 32% SF (425 sightings in 1323 surveys) in 1994 to 8.5% SF (93 sightings in 1095 surveys) in 2005, averaging ~18% decline per year. The decline has gone virtually unnoticed. This study highlights the importance of protecting marine communities for the preservation of fishery resources and shows the importance of recording all marine species extractions. It also demonstrates the value and application of trained volunteer divers for monitoring temporal trends and species interactions of marine communities. This work was presented at the Summer 2006 American Elasmobranch Society meeting in New Orleans.
This paper summarized the first five years of monitoring of the Little Cayman West End aggregation, including a summary of spawning activity, total numbers of fish present at the aggregation each year, coloration, and behavior.
This paper documents attacks by the isopod Excorallana tricornis tricornis on Nassau grouper caught in Antillian fish traps during the post-spawning season of Spring 2005. These findings were documented during Grouper Moon research by REEF and Cayman Islands Department of the Environment staff. Fish were being trapped in order to acoustically tag individuals from sites around Little Cayman Island in order to better understand what percentage of reproductive-size individuals attend the aggregation each year. The paper discusses the apparent energetic costs associated with spawning. This work was also presented as a poster at the 56th Gulf and Caribbean Fisheries Institute Meeting in 2005, and a summary of the poster is posted online (POSTER).
Though declines in coral health have been documented worldwide, the effects of this decline on reef inhabitants are poorly studied. Studies monitoring fish abundances through coral declines are often inconclusive or contradictory in their results. This study uses fish assemblage data from REEF's database, as well as bleaching data compiled by ReefBase and reef health data collected by Reef Check, to correlate reef inhabitant abundance with bleaching events. Data are analyzed with respect to species, reef location, bleaching severity, and recovery time. Preliminary results show that the majority of species do not change in abundance following a bleaching event. Of those that do change, both increases and decreases are seen, and the direction of change, even within a single species, is often dependent on the time since the event. This suggests that a local decline in coral health may not have an immediate negative impact on the community and that a window of opportunity to preserve community structure following coral mortality may exist. This work was presented at the Summer 2006 International American Society of Limnology and Oceanography (ASLO) meeting in Spain.
This study used REEF data from Bonaire, an area where several thousand REEF surveys have been conducted, to evaluate patterns in species occurrence. Their results suggest that species interactions, and/or species-habitat relationships may be important behavioral attributes mediating the local structure of fish assemblages on these coral reefs. This work was also presented at the International Coral Reef Symposium in 2004.
REEF data were one of three datasets used in the most recent stock assessment of the Goliath grouper, a species that is currently protected from harvest due to very low numbers in the 1980s. Because this species is not fished, fisheries managers must use fisheries-independent datasets and the REEF database represents a valuable source of this information.
Sightings data submitted to REEF's Exotic Species Sighting Program through 2002 are summarized in this paper. The data show a hot-spot of non-native marine fishes along south Florida (Broward and Palm Beach Counties). The authors evaluated potential vectors of introduction and pinpointed the aquarium trade as the likely source.
This paper summarizes the finding from the 2002 REEF Grouper Moon Project, which documented the characteristics of a newly discovered Nassau grouper spawning aggregation. At its peak, over 5,000 Nassau grouper were present at the site. Significant contributions include the visual and video documentation of four nights of spawning of Nassau grouper, the description of crepuscular and lunar movements and color phase shifts in the grouper, and the documentation of courtship/spawning behavior in ten additional species. This paper was also presented at the 2002 Gulf and Caribbean Fisheries Institute Meeting.
