SEAMAP Real-time Plots for the year 2013
Week 3
Below is the third preliminary data summary for the 2013 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 17-25 by the NOAA vessel Oregon II and Texas vessels. Catch data from the Oregon II were taken with a 40-ft trawl, while data from the Texas vessels were collected with 20-ft trawls.
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 80.1 lb/hr in 11 fm at 28° 57' N. lat. and 94° 08' W. long. The highest catch rate of white shrimp was 57.7 lb/hr in 7 fm at 29° 26' N. lat. and 94° 21' W. long. The highest catch rate of pink shrimp was 2.1 lb/hr in 11 fm at 28° 57' N. lat. and 94° 08' W. long. The maximum total catch rate excluding the three shrimp species was 639 lb/hr in 7 fm at 29° 26' N. lat. and 94° 21' W. long.
