SEAMAP Real-time Plots for the year 2022

Week 1

Attached is the first preliminary data summary for the 2022 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 4-7 by Mississippi and Alabama on the vessel Tommy Munro and from June 7-9 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 73.6 lb/hr in 9 fm at 29° 51' N. lat. and 88° 28' W. long. The highest catch rate of white shrimp was 43.1 lb/hr in 5 fm at 28° 59' N. lat. and 90° 43' W. long. The highest catch rate of pink shrimp was 1.9 lb/hr in 28 fm at 30° 04' N. lat. and 86° 48' W. long. The maximum total catch rate excluding the three shrimp species was 515 lb/hr in 10 fm at 30° 07' N. lat. and 86° 12' W. long.
