SEAMAP Real-time Plots for the year 2006

Week 5

Below is the fifth preliminary data summary for the 2006 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling July 3 through July 10 by the NMFS vessel Oregon II and 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 from west of the Mississippi River indicated that the highest catch rate of brown shrimp was 105.1 lb/hr in 16 fm at 28° 42' N. lat. and 94° 10' W. long. The highest catch rate of white shrimp was 23.8 lb/hr in 4 fm at 29° 10' N. lat. and 90° 15' W. long. The highest catch rate of pink shrimp was 0.66 lb/hr in 9 fm at 29° 13' N. lat. and 95° 58' W. long. The maximum total catch rate excluding the three shrimp species was 690 lb/hr in 10 fm at 29° 08' N. lat. and 92° 24' W. long.

Sampling coverage for the next weekly report will be by the NMFS vessel Oregon II.
