SEAMAP Real-time Plots for the year 2012
Week 7
Below is the seventh and final data summary for the 2012 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from July 6 through July 15 by the NOAA vessel Oregon IIand two Texas vessels. Catch data from the Oregon II 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 0.8 lb/hr in 12 fm at 27° 35' N. lat. and 97° 02' W. long. The highest catch rate of pink shrimp was 4.3 lb/hr in 18 fm at 27° 58' N. lat. and 83° 32' W. long. The highest catch rate of white shrimp was 9.2 lb/hr in 7 fm at 27° 49' N. lat. and 97° 00' W. long. The maximum total catch rate excluding the three shrimp species was 577 lb/hr in 14 fm at 26° 01' N. lat. and 82° 26' W. long.
