SEAMAP Real-time Plots for the year 2011
Week 1
Below is the first 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 1 through June 5 by the Mississippi vessel Tommy Munro and by Texas vessels. Catch data from the Tommy Munro were taken with a 40-ft trawl. Catch data from the Texas vessels were taken with 20-ft trawls.
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 74.3 lb/hr in 5 fm at 29° 16' N. lat. and 94° 41' W. long. The highest catch rate of white shrimp was 15.9 lb/hr in 11 fm at 28° 19' N. lat. and 96° 13' W. long. The highest catch rate of pink shrimp was 16.2 lb/hr in 9 fm at 26° 18' N. lat. and 97° 09' W. long. The maximum total catch rate excluding the three shrimp species was 2,854 lb/hr in 49 fm at 29° 15' N. lat. and 88° 17' W. long.
Sampling coverage for the next weekly report will be by Texas vessels and the NMFS vessel Oregon II.
