Vertical Line Survey (2011)

The Southeast Fisheries Science Center Mississippi Laboratories conducts standardized fisheries independent resource surveys in the Gulf of Mexico, South Atlantic, and U.S. Caribbean to provide abundance and distribution information to support regional and international stock assessments. In 2011, the R/V Gandy conducted a survey of reef fish located on the continental shelf and shelf-edge of the western Gulf of Mexico using bandit reels (vertical lines). Data were collected using using ten gangions, five #11/0 circle hooks and five #8/0 circle hooks. The data provided additional life history information for a red snapper benchmark stock assessment.

To provide life history information to support red snapper assessments.

Data are reviewed and edited for accuracy by chief scientists.

Data resides in the laboratories’ centralized database (Oracle). Security patches are applied to the database and host environment immediately after their release. In addition, Security benchmarks are applied to the database and host environment. Data residing in the centralized database (Oracle) is backed up nightly. Backup sets are placed on the laboratories’ Networked Attached Storage (NAS) environment. Security patches/updates are immediately applied to the host environment. Data is stripped/mirrored using RAID 50 technology to protect data from disk failure. Nightly backups are preformed and files are written to magnetic tape and stored in an onsite / offsite location.

All data (e.g. station location, gear characteristics, fish identifications, length measurements, environmental variables, etc.) were recorded on paper and then manually entered into a database. All data are checked for completeness and accuracy by chief scientists.
