SEAMAP Real-time Plots for the year 2010
Week 2
Below is the second preliminary data summary for the 2010 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 2 - 11 by the Alabama vessel Alabama Discovery, the Louisiana vessel Pelican, and by Texas vessels. Catch data from the Alabama Discovery and the Pelican 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 indicated that the highest catch rate of brown shrimp was 49.9 lb/hr in 19 fm at 28° 43' N. lat. and 90° 12' W. long. The highest catch rate of white shrimp was 65.7 lb/hr in 9 fm at 28° 59' N. lat. and 89° 29' W. long. The highest catch rate of pink shrimp was 4.8 lb/hr in 6 fm at 26° 05' N. lat. and 97° 08' W. long. The maximum total catch rate excluding the three shrimp species was 1,639 lb/hr in 9 fm at 28° 59' N. lat. and 89° 29' W. long.
Sampling coverage for the next weekly report will be by the NMFS vessel Oregon II.
