* » Abstract |
We examined queen conch populations on the northeastern coast of St. Croix, U.S. Virgin Islands, using a radial survey sampling technique with sample sites stratified by depth, habitat type, and management regime, encompassing both open and closed fishing areas. We completed 503 radial surveys and located 4773 conch, representing a cumulative density of approximately 302 conch per hectare. Densities of juvenile conch were highest in 5090 patchy seagrass beds in Buck Island Reef National Monument (BIRNM) due to high numbers of small 79 cm conch. Overall length frequencies showed a bimodal distribution, driven largely by juvenile conch found within the BIRNM. Length distributions by habitat were variable but showed a trend toward larger conch in reef, macroalgae, and sand habitats compared to a more even distribution in seagrass. Densities of adults were highest inside the BIRNM in 1050 patchy seagrass where several conch were observed mating and laying egg masses. |
* Purpose |
To determine densities of queen conch on the northeastern coast of St. Croix from fishery-independent surveys to enhance stock assessment efforts. |

» Quality Control Procedures Employed |
Each sample was assigned a unique identification code. Field collected samples were tagged redundantly (e.g. one label inside of the collection vessel and a matching label attached to the outside of the vessel). The identifier and its associated information (e.g. date, location, habitat) was recorded on field data sheets. Once a sample arrived at the laboratory, the label remained with the sample throughout the various stages of sample processing. After data were entered into an Excel spreadsheet or similar database file, the information was printed out and compared against the field data sheets by two biologists. Corrections were made at this time and saved. The electronic file was also sorted and examined by the Lab Supervisor or other project personnel in a variety of ways to look for outliers, missing data, and other potential errors. |

» Description |
After sample collection, field data were entered into an Excel spreadsheet or database file (DBF) using database manager software. A text file was created to describe these data and associated variables. Entered data were checked against the field sheets by two biologists to minimize entry errors. Samples were processed in the laboratory, sorted, specimens identified and measured, and information was entered into an Excel spreadsheet or DBF file. Files were printed out and compared against original data sheets by two biologists for data entry errors. Corrections were made at this time, the electronic file was saved, and a back-up copy made. Hard copies of the QCd files were printed and stored in the project folder along with the original field and laboratory data sheets. The electronic file was also sorted and examined by the Lab Supervisor or other project personnel in a variety of ways to look for outliers, missing data, and other potential errors. Verified data files were then saved electronically on the Galveston Laboratory server and backed-up as needed. |
