SEAMAP Real-time Plots for the year 2019

Week 4

Below is the fourth preliminary data summary for the 2019 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 27 - July 2 by NMFS on the 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 53.0 lb/hr in 20 fm at 28° 40' N. lat. and 92° 46' W. long. The highest catch rate of white shrimp was 14.8 lb/hr in 12 fm at 28° 58' N. lat. and 93° 28' W. long. The highest catch rate of pink shrimp was 0.3 lb/hr in 15 fm at 28° 48' N. lat. and 92° 58' W. long. The maximum total catch rate excluding the three shrimp species was 3,237 lb/hr in 13 fm at 29° 04' N. lat. and 93° 18' W. long.
