SEAMAP Real-time Plots for the year 2015


Week 4

Below is the fourth preliminary data summary for the 2015 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 8 - 29 by the NOAA vessel Oregon II, the Florida vessel Tommy Munro, and the Alabama vessel, Alabama Discovery. 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 116.7 lb/hr in 21 fm at 28° 38' N. lat. and 93° 44' W. long. The highest catch rate of white shrimp was 36.9 lb/hr in 12 fm at 29° 00' N. lat. and 94° 32' W. long. The highest catch rate of pink shrimp was 45.2 lb/hr in 6 fm at 25° 49' N. lat. and 81° 48' W. long. The maximum total catch rate excluding the three shrimp species was 2,864 lb/hr in 15 fm at 26° 32' N. lat. and 82° 43' W. long.
