SEAMAP Real-time Plots for the year 2014

Week 4

Below is the fourth preliminary data summary for the 2014 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from July 2 - 5 by the NOAA Vessel Oregon II. Catch data from the 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 indicated that the highest catch rate of brown shrimp was 54.0 lb/hr in 8 fm at 29° 18' N. lat. and 89° 01' W. long. The highest catch rate of white shrimp was 7.0 lb/hr in 14 fm at 28° 47' N. lat. and 91° 41' W. long. The highest catch rate of pink shrimp was 2.3 lb/hr in 11 fm at 28° 36' N. lat. and 90° 50' W. long. The maximum total catch rate excluding the three shrimp species was 1,232 lb/hr in 32 fm at 28° 17' N. lat. and 90° 44' W. long.
