SEAMAP Real-time Plots for the year 2018

Week 3

Below is the third 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 13-21 by the Florida vessel Tommy Munro and the Louisiana vessel Pelican. 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 48.5 lb/hr in 21 fm at 28° 39' N. lat. and 91° 54' W. long. The highest catch rate of white shrimp was 4.9 lb/hr in 6 fm at 28° 45' N. lat. and 91° 05' W. long. The highest catch rate of pink shrimp was 29.9 lb/hr in 10 fm at 25° 00' N. lat. and 81° 51' W. long. The maximum total catch rate excluding the three shrimp species was 2056 lb/hr in 20 fm at 29° 07' N. lat. and 85° 10' W. long.
