SEAMAP Real-time Plots for the year 2011
Week 5
Below is the fifth preliminary data summary for the 2011 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 27 through July 3 by the NMFS vessel Oregon II. Catch data from the Oregon II were taken with a 40-ft 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 156.3 lb/hr in 16 fm at 28° 29' N. lat. and 95° 22' W. long. The highest catch rate of white shrimp was 178.2 lb/hr in 10 fm at 27° 25' N. lat. and 97° 12' W. long. The highest catch rate of pink shrimp was 1.0 lb/hr in 9 fm at 28° 57' N. lat. and 94° 42' W. long. The maximum total catch rate excluding the three shrimp species was 990.5 lb/hr in 8 fm at 29° 20' N. lat. and 94° 15' W. long.
