| Title: | Effect of lionfish densities on native coral-reef fishes from Lee Stocking Island, Bahamas during 2009-2012 (Biodiversity Loss Effects Lionfish project) (NCEI Accession 0278350) |
| Abstract: | This dataset contains biological, physical, and survey - biological data collected at Tropical Marine Lab at Lee Stocking Island during deployment LSI_Reef_Surveys_09-12 at Lee Stocking Island, Bahamas from 2011-06-26 to 2011-08-21. These data include abundance, density, and species. These data were collected by Dr Mark Hixon of University of Hawaii as part of the "Mechanisms and Consequences of Fish Biodiversity Loss on Atlantic Coral Reefs Caused by Invasive Pacific Lionfish (BiodiversityLossEffects_lionfish)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-05-15. The following is the text of the dataset description provided by BCO-DMO: Effect of lionfish densities on native coral-reef fishes Dataset Description: This was a field experiment conducted on artificial patch reefs to test for the effect of lionfish density on native fish abundance, diversity, and community structure. The experiment used 10 reefs which were manipulated so that 4 reefs had 0 lionfish on them (controls), and 6 each had a unique density of lionfish (average = 1, 2, 4, 7, 10, or 12 lionfish). Complete censuses of the native fish population on each reef were conducted weekly for 6-weeks during the summer recruitment season.

| Supplementary information: | Acquisition Description: This was a field experiment conducted on artificial patch reefs to test for effects of invasive red lionfish density on native coral-reef fishes. Four reefs were used as 0-lionfish control reefs and there was one reef per remaining lionfish treatment (2, 4, 6, 8, 10, and 12 lionfish/m 2 ). Using SCUBA and handnets, we collected lionfish ranging in initial size from 40 to 71mm total length [TL] from nearby reefs. Each lionfish was given a unique elastomer tag (Northwest Marine Technology Inc., Shaw Island, WA, USA) to differentiate between lionfish at the start of the experiment and any new immigrants over the course of the study and to monitor demographic rates as part of another study (see related files and references). Treatments were started on all reefs within a 2-week period. To maintain treatments, we monitored lionfish density during weekly visits and removed any new lionfish recruits (total of 15 throughout experiment) and immigrants (total of 5 throughout experiment). In addition, we removed resident native piscivores and standardized the number of Nassau grouper ( Epinephelus striatus ) and territorial damselfishes ( Stegastes spp . ) weekly to mitigate any confounding effects of these strong interactors on fish recruitment. Of the lionfish initially placed on the reefs, only 6 out of 40 disappeared. To account for the small changes in lionfish density throughout the experiment, we averaged the weekly lionfish densities on each reef over the course of the experiment (1, 2, 4, 7, 10, and 12 lionfish/m 2 ). Following the establishment of lionfish density treatments, a pair of divers using SCUBA censused the entire fish community on each reef weekly for 7 weeks, recording the species, abundance, and body size (TL estimated to the nearest centimeter) of all fish present both on the reefs and within a 1-m radius around the reefs. Divers slowly approached the reefs and first counted all planktivorous and active species hovering above the reefs from a distance of approximately 3 m. From a distance of 1 m, the divers slowly circled the reefs and counted all other species, using dive lights to count cryptic species in holes. |
