SEAMAP Real-time Plots for the year 2017

Week 1

Below is the first preliminary data summary for the 2017 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from May 30 — June 1 by the Mississippi vessel Tommy Munro. 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 17.3 lb/hr in 28 fm at 29° 23' N. lat. and 88° 40' W. long. The highest catch rate of white shrimp was 53.2 lb/hr in 7 fm at 30° 11' N. lat. and 88° 25' W. long. The highest catch rate of pink shrimp was 1.5 lb/hr in 21 fm at 29° 44' N. lat. and 88° 20' W. long. The maximum total catch rate excluding the three shrimp species was 748 lb/hr in 7 fm at 30° 11' N. lat. and 88° 25' W. long.
