SEAMAP Real-time Plots for the year 2007

Week 2

Below is the second preliminary data summary for the 2007 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico . This week's summary includes sampling June 11 through June 18 by the Mississippi vessel Tommy Munro and the NMFS vessel Oregon II. Catch data from the Tommy Munro and 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 east of the Mississippi River indicated that the highest catch rate of brown shrimp was 69.4 lb/hr in 25 fm at 29° 16' N. lat. and 88° 52' W. long. The highest catch rate of white shrimp was 9.3 lb/hr in 25 fm at 29° 16' N. lat. and 88° 52' W. long. The highest catch rate of pink shrimp was 2.8 lb/hr in 11 fm at 29° 22' N. lat. and 88° 54' W. long. The maximum total catch rate excluding the three shrimp species was 489 lb/hr in 41 fm at 29° 16' N. lat. and 88° 29' W. long.

The catch data from Texas indicated that the highest catch rate of brown shrimp was 110.7 lb/hr in 11 fm at 26° 47' N. lat. and 97° 15' W. long. The highest catch rate for white shrimp was 0.9 lb/hr in 6 fm at 27° 24' N. lat. and 97° 17' W. long. The highest catch rate of pink shrimp was 51.2 lb/hr in 11 fm at 26° 47' N. lat. and 97° 15' W. long. The maximum total catch rate excluding the three shrimp species was 313 lb/hr in 11 fm at 26° 47' N. lat. and 97° 15' W. long.

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