SEAMAP Real-time Plots for the year 2023
Week 4
Below is the fourth preliminary data summary for the 2023 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from July 11 – 15 by NMFS on the vessel Oregon II. Catch data were taken with a 40-ft trawl.
Plotted catch rates have been converted to pounds per hour for a 40-ft trawl. 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 95.1 lb/hr in 16 fm at 28° 50' N. lat. and 92° 07' W. long. The catch data indicated that the highest catch rate of white shrimp was 6.8 lb/hr in 7 fm at 29° 01' N. lat. and 91° 41' W. long. The highest catch rate of pink shrimp was 0.9 lb/hr in 10 fm at 28° 41' N. lat. and 90° 37' W. long. The maximum total catch rate excluding the three shrimp species was 341 lb/hr in 16 fm at 28° 50' N. lat. and 92° 07' W. long. Back to 2023
