USGS 2001 Buck Island National Monument Cryptic Fish SurveyEntry ID: BuckIslandFish
Abstract: Because cryptic fishes are difficult to accurately survey, they are undersampled components of coral reef habitats. Fifty-eight enclosed stations were sampled in shoreline, nearshore reef, lagoon, backreef, forereef, and bank/shelf habitats with an ichthyocide (rotenone) at Buck Island Reef National Monument, St. Croix, U.S. Virgin Islands in July-August 2001. Our samples included 228 fish species ... in 55 families, including 60 species previously unreported from St. Croix. Fish assemblages varied across habitat zones with the shoreline assemblage the most distinct. Only 8% of the species were present in all habitats. The use of rotenone is controversial but important for obtaining reasonably complete inventories of reef fishes. For more information, see Smith-Vaniz, W.F., H.L. Jelks, and L.A. Rocha. 2006. Relevance of cryptic fishes in biodiversity assessments: a case study at Buck Island Reef National Monument, St. Croix. Bulletin of Marine Science 79:17-48.
Purpose: The objectives of the study were to: (1) present a base-line inventory of cryptic reef and shoreline fishes inhabiting shallow-water habitats at Buck Island Reef National Monument; (2) compare fish distributions and relative abundance patterns among the sampled habitats; (3) compare the results of ichthyocide (rotenone) sampling with independently conducted underwater visual censuses (UVC); and (4) discuss misconceptions about rotenone and suggest guidelines for its use in marine habitats.

Quality ATTRIBUTE ACCURACY REPORT: Care was taken to insure quality control. Fishes collected with Rotenone were vouchered at Florida Museum of Natural History so identifications can be verified or altered as taxonomies are changed through time. The dataset only contains these vouchered specimens.
HORIZONTAL POSITIONAL ACCURACY REPORT: A handheld GPS and a field base map were used to locate sites. Distance to shore was based on GIS measurements. Latitude and longitude were converted to decimal degrees and rounded to five decimal places.

OBIS-USA renders information prepared by contributors accessible through dynamic on-line publication. It does not peer-review the quality of the data provided. However, it is confident that the data ... are the best available in electronic form. OBIS-USA does not own or try to control or limit the use of any data or products accessible through its website.

Users must recognize that the analysis and interpretation of data requires background knowledge and expertise about marine biodiversity (including ecosystems and taxonomy). Users should be aware of possible errors in the use of species names, geo-referencing, data handing and mapping. They should crosscheck their results for possible errors, and qualify their interpretation of any results accordingly. Appropriate caution is thus necessary in the interpretation of results derived from OBIS-USA.
Use Constraints Prior to use of these records in any analysis or report, Howard Jelks must be notified and if used the provenance of the original data must be acknowledged. Acknowledge the use of specific records from contributing USGS databases and acknowledge the use of the OBIS-USA facility. Recognize the limitations of data in OBIS-USA.
