SEAMAP Real-time Plots for the year 2021

Week 4

Attached is the fourth preliminary data summary for the 2021 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from July 14-19 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 66.3 lb/hr in 30 fm at 28° 12' N. lat. and 94° 37' W. long. The highest catch rate of white shrimp was 14.2 lb/hr in 11 fm at 28° 56' N. lat. and 94° 05' W. long. The highest catch rate of pink shrimp was 3.1 lb/hr in 13 fm at 28° 58' N. lat. and 92° 52' W. long. The maximum total catch rate excluding the three shrimp species was 1,091 lb/hr in 32 fm at 28° 21' N. lat. and 93° 28' W. long.
