SEAMAP Real-time Plots for the year 2010

Week 5

Below is the fifth preliminary data summary for the 2010 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 26 to July 5 by the NMFS vessel Oregon II. Catch data from the Oregon II were taken with a 40-ft 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 104.7 lb/hr in 18 fm at 26° 37' N. lat. and 97° 04' W. long. The highest catch rate of white shrimp was 48.3 lb/hr in 13 fm at 28° 28' N. lat. and 95° 45' W. long. The highest catch rate of pink shrimp was 11.8 lb/hr in 10 fm at 26° 27' N. lat. and 97° 10' W. long. The maximum total catch rate excluding the three shrimp species was 1,319 lb/hr in 26 fm at 28° 28' N. lat. and 90° 19' W. long.

Sampling coverage for the next weekly report will be by the NMFS vessel Oregon II.
