SEAMAP Real-time Plots for the year 2010


Week 3

Enclosed is the third 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 16 - 17 by Texas vessels. Catch data from the Texas vessels were taken 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 29.3 lb/hr in 6 fm at 29° 36' N. lat. and 93° 47' W. long. The highest catch rate of white shrimp was 14.1 lb/hr in 9 fm at 28° 21' N. lat. and 96° 17' W. long. The maximum total catch rate excluding the three shrimp species was 240 lb/hr in 9 fm at 28° 21' N. lat. and 96° 17' W. long.

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