SEAMAP Real-time Plots for the year 2006
Week 4
Below is the fourth preliminary data summary for the 2006 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling June 23 through July 3 by the NMFS vessel Oregon II and the Texas vessels. Catch data from the Oregon II were taken with a 40-ft trawl. Catch data from the Texas vessels were taken with 20-ft trawls.
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 off Texas indicated that the highest catch rate of brown shrimp was 135.1 lb/hr in 10 fm at 28° 35' N. lat. and 95° 38' W. long. The highest catch rate of white shrimp was 144.7 lb/hr in 5 fm at 29° 30' N. lat. and 94° 24' W. long. The highest catch rate of pink shrimp was 10.8 lb/hr in 8 fm at 26° 04' N. lat. and 97° 07' W. long. The maximum total catch rate excluding the three shrimp species was 4,540.1 lb/hr in 9 fm at 28° 16' N. lat. and 96° 24' W. long.
Sampling coverage for the next weekly report will be by the NMFS vessel Oregon II and the Mississippi vessel Tommy Munro.
