SEAMAP Real-time Plots for the year 2006

Week 6

Below is the six and final preliminary data summary for the 2006 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico . This week's summary includes sampling July 10 through July 16 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 from west of the Mississippi River indicated that the highest catch rate of brown shrimp was 81.2 lb/hr in 14 fm at 29° 04' N. lat. and 89° 40' W. long. The highest catch rate of white shrimp was 12.6 lb/hr in 11 fm at 28° 38' N. lat. and 91° 06' W. long. The highest catch rate of pink shrimp was 1.9 lb/hr in 12 fm at 29° 00' N. lat. and 92° 09' W. long. The maximum total catch rate excluding the three shrimp species was 1,247 lb/hr in 18 fm at 28° 33' N. lat. and 90° 31' W. long.
