SEAMAP Real-time Plots for the year 2018

Week 5

Below is the fifth preliminary data summary for the 2018 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from July 3-17 by the NOAA Fisheries 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 22.6 lb/hr in 32 fm at 28° 17' N. lat. and 93° 06' W. long. The highest catch rate of white shrimp was 3.2 lb/hr in 8 fm at 29° 17' N. lat. and 92° 54' W. long. The highest catch rate of pink shrimp was 20.32 lb/hr in 12 fm at 29° 25' N. lat. and 85° 07' W. long. The maximum total catch rate excluding the three shrimp species was 758 lb/hr in 53 fm at 28° 15' N. lat. and 90° 12' W. long.
