SEAMAP Real-time Plots for the year 2010
Week 4
Enclosed is the fourth preliminary data summary for the 2010 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling on June 21 by Texas vessels. 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 indicated that the highest catch rate of brown shrimp was 3.8 lb/hr in 15 fm at 25° 58' N. lat. and 97° 00' W. long. The highest catch rate of white shrimp was 0.9 lb/hr in 3 fm at 29° 17' N. lat. and 94° 45' W. long. The highest catch rate of pink shrimp was 3.8 lb/hr in 15 fm at 26° 09' N. lat. and 97° 00' W. long. The maximum total catch rate excluding the three shrimp species was 839 lb/hr in 2 fm at 29° 14' N. lat. and 94° 51' W. long.
