SEAMAP Real-time Plots for the year 2012


Week 2

Below is the second preliminary data summary for the 2012 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 5 through June 10 by the NOAA vessel Oregon II, Louisiana vessel Pelican, and three Texas vessels. Catch data from the Oregon II and Pelican were taken with a 40-foot trawl while data from Texas were collected with a 20-foot trawl

Plotted catch rates have been converted to pounds per hour for a 40-ft trawl (20-ft trawl x 2) 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 124.3 lb/hr in 10 fm at 28° 47' N. lat. and 90° 49' W. long. The highest catch rate of white shrimp was 17.7 lb/hr in 7 fm at 29° 24' N. lat. and 94° 31' W. long. The highest catch rate of pink shrimp was 0.13 lb/hr in 9 fm at 28° 45' N. lat. and 90° 58' W. long. The maximum total catch rate excluding the three shrimp species was 506 lb/hr in 13 fm at 28° 38' N. lat. and 90° 25' W. long.
