SEAMAP Real-time Plots for the year 2011
Week 3
Below is the third 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 8 through June 18 by the Florida vessel Tommy Munro and by the Alabama vessel Discoverer. Catch data from the Tommy Munro and Discoverer 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 0.8 lb/hr in 7 fm at 29° 44' N. lat. and 85° 27' W. long. The highest catch rate of pink shrimp was 86.7 lb/hr in 15 fm at 24° 47' N. lat. and 82° 31' W. long. The maximum total catch rate excluding the three shrimp species was 2,344 lb/hr in 18 fm at 25° 40' N. lat. and 82° 38' W. long.
The NMFS vessel Oregon II is still being repairded, but should hopefully resume the survey this week.
