Madison-Swanson MPA reef fish video survey

Metadata Updated: April 1, 2024

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. The reef fish survey of Madison-Swanson and Steamboat Lumps MPA is conducted primarily on the along topographic features (e.g. reefs, banks and ledges) of the MPA. A two-stage sampling design is used with the first stage or primary sampling units defined by geographic/geoform strata including ridges, pinnacles, rubble and sand flats and the second stage being randomly selected sites within the geoform strata. Sampling is conducted using a video camera array. No biological sampling is coupled with the survey because of the areas status as an MPA. The camera array consists of four housings positioned orthogonally and center mounted at a height of 51 cm above the bottom of the array. Each housing contains a pair of black-and-white Videre stereo cameras along with a color mpeg camera. Sampling of reef sites with video cameras occurs only during daylight hours, with the first gear deployment one hour after sunrise and the last gear retrieval one hour prior to sunset. Video arrays soak for 35 minutes. Habitat mapping was conducted using a multibeam echosounder by USGS. At each site hydrological data is collected using Conductivity Temperature Depth sensor (CTD).

Lineage Reef fish abundance and size data are generated from videos. An index of abundance for each species is determined as the MaxNo, the maximum number of a taxon that is in the field of view in a single video frame. Fish lengths are determined using laser reference points or stereo video processing. Data are entered into the database.
