SEAMAP Real-time Plots for the year 2012
Week 6
Below is the sixth preliminary data summary for the 2012 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 28 through July 8 by the NOAA vessel Oregon II, the Florida vessel Tommy Munro, and three Texas vessels. Catch data from the Oregon II and Tommy Munro were taken with a 40-foot trawl, while the data from the Texas vessels were taken with a 20-foot trawl.
Plotted catch rates have been converted to pounds per hour for a 40-ft trawl (20-ft trawl x 2). Shrimp counts are heads-on. The squares on the charts are 10-minute grids. The number in each grid square is the average catch or count from all stations (may be one or more stations) that were sampled within a particular grid. The sampling stations were located randomly by depth zone.
The catch data indicated that the highest catch rate of brown shrimp was 10.8 lb/hr in 8 fm at 29° 12' N. lat. and 94° 42' W. long. The highest catch rate of white shrimp was 21.4 lb/hr in 6 fm at 29° 25' N. lat. and 96° 16' W. long. The highest catch rate of pink shrimp was 17.1 lb/hr in 14 fm at 28° 12' N. lat. and 83° 34' W. long. The maximum total catch rate excluding the three shrimp species was 2,710 lb/hr in 12 fm at 29° 11' N. lat. and 84° 00' W. long.
