SEAMAP Real-time Plots for the year 2021

Week 1

Attached is the first preliminary data summary for the 2021 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 1-4 by Mississippi and Alabama on the vessel Tommy Munro and from June 2-4 by Louisiana on the vessel Pelican. 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 78.8 lb/hr in 5 fm at 28° 57' N. lat. and 90° 23' W. long. The highest catch rate of white shrimp was 7.1 lb/hr in 6 fm at 28° 39' N. lat. and 91° 11' W. long. The highest catch rate of pink shrimp was 1.7 lb/hr in 15 fm at 29° 29' N. lat. and 85° 31' W. long. The maximum total catch rate excluding the three shrimp species was 841 lb/hr in 19 fm at 28° 89' N. lat. and 89° 39' W. long.
