SEAMAP Real-time Plots for the year 2007
Week 3
Below is the third preliminary data summary for the 2007 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico . This week's summary includes sampling June 16 through June 24 by the NMFS vessel Oregon II and by 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 Texas indicated that the highest catch rate of brown shrimp was 114.4 lb/hr in 15 fm at 27° 59' N. lat. and 96° 31' W. long. The highest catch rate for white shrimp was 29.3 lb/hr in 6 fm at 28° 12' N. lat. and 96° 26' W. long. The highest catch rate of pink shrimp was 15.5 lb/hr in 9 fm at 28° 58' N. lat. and 94° 19' W. long. The maximum total catch rate excluding the three shrimp species was 858.6 lb/hr in 7 fm at 28° 15' N. lat. and 96° 29' W. long. Sampling coverage for the next weekly report will be by the NMFS vessel Oregon II.
