SEAMAP Real-time Plots for the year 2012
Week 1
Below is the first preliminary data summary for the 2012 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from May 29 through May 31 by the Mississippi vessel Tommy Munro. Catch data from the Tommy Munro 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 37.5 lb/hr in 15 fm at 29° 59' N. lat. and 88° 25' W. long. The highest catch rate of white shrimp was 2.9 lb/hr in 15 fm at 29° 59' N. lat. and 88° 25' W. long. The highest catch rate of pink shrimp was 13.1 lb/hr in 10 fm at 30° 07' N. lat. and 88° 12' W. long. The maximum total catch rate excluding the three shrimp species was 1,371 lb/hr in 16 fm at 29° 57' N. lat. and 88° 19' W. long.
