SEAMAP Real-time Plots for the year 2017

Week 3

Below is the third preliminary data summary for the 2017 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 17 — July 4 by the Alabama vessel Alabama Discovery, Florida vessel Tommy Munro, the Louisiana vessel Point Sur, and the NOAA 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 92.1 lb/hr in 22 fm at 29° 07' N. lat. and 88° 56' W. long. The highest catch rate of white shrimp was 29.8 lb/hr in 10 fm at 28° 41' N. lat. and 90° 27' W. long. The highest catch rate of pink shrimp was 10.0 lb/hr in 11 fm at 27° 44' N. lat. and 83° 06' W. long. The maximum total catch rate excluding the three shrimp species was 1480 lb/hr in 28 fm at 27° 51' N. lat. and 84° 00' W. long.
