SEAMAP Real-time Plots for the year 2018

Week 1

Below is the first preliminary data summary for the 2018 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 5-12 by the Mississippi vessel Tommy Munro and the NMFS 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 45.4 lb/hr in 14 fm at 27° 24' N. lat. and 97° 06' W. long. The highest catch rate of white shrimp was 5.1 lb/hr in 9 fm at 27° 19' N. lat. and 97° 16' W. long. The highest catch rate of pink shrimp was 4.7 lb/hr in 9 fm at 27° 19' N. lat. and 97° 16' W. long. The maximum total catch rate excluding the three shrimp species was 376 lb/hr in 8 fm at 29° 44' N. lat. and 88° 33' W. long.
