SEAMAP Real-time Plots for the year 2009
Week 6
Enclosed is the sixth preliminary data summary for the 2009 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from July 6 through July 12 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 67.9 lb/hr in 15 fm at 28° 51' N. lat. and 93° 03' W. long. The highest catch rate of white shrimp was 40.1 lb/hr in 8 fm at 29° 26' N. lat. and 93° 07' W. long. The highest catch rate of pink shrimp was 0.8 lb/hr in 12 fm at 28° 56' N. lat. and 91° 53' W. long. The maximum total catch rate excluding the three shrimp species was 2,063 lb/hr in 14 fm at 28° 33' N. lat. and 90° 42' W. long.
