SEAMAP Real-time Plots for the year 2021

Week 3

Attached is the third 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 4-14 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 248.3 lb/hr in 20 fm at 26° 02' N. lat. and 96° 53' W. long. The highest catch rate of white shrimp was 32.0 lb/hr in 9 fm at 29° 09' N. lat. and 94° 19' W. long. The highest catch rate of pink shrimp was 9.0 lb/hr in 9 fm at 27° 05' N. lat. and 97° 20' W. long. The maximum total catch rate excluding the three shrimp species was 822 lb/hr in 9 fm at 27° 05' N. lat. and 97° 20' W. long.
