SEAMAP Real-time Plots for the year 2009
Week 5
Below is the fifth preliminary data summary for the 2009 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 28 through July 2 by the NMFS vessel Oregon II and by the Mississippi vessel Tommy Munro. Catch data from the Oregon II and 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 129.9 lb/hr in 14 fm at 28° 44' N. lat. and 93° 47' W. long. The highest catch rate of white shrimp was 55.1 lb/hr in 7 fm at 29° 23' N. lat. and 94° 34' W. long. The highest catch rate of pink shrimp was 4.6 lb/hr in 12 fm at 29° 05' N. lat. and 93° 20' W. long. The maximum total catch rate excluding the three shrimp species was 1,742 lb/hr in 8 fm at 29° 18' N. lat. and 94° 28' W. long.
