SEAMAP Real-time Plots for the year 2002


Week 5

This is the fifth preliminary data summary for the 2002 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from July 1 through July 7 by the NOAA Ship OREGON II off the Texas and Louisiana coasts. Catch data from the OREGON II were taken with a 40-ft trawl.

Catch rates have been converted to pounds per hour for a 40-ft trawl. Shrimp counts are heads-off. Catch rates for finfish are given in the charts divided by 10; e.g., a charted catch rate of 19 means 190 lb/hr. The squares on the charts are 10-minute grids and contain an average catch or count from one or more sampling stations within a particular grid. The sampling stations were located randomly by depth zone.

No samples were taken east of the Mississippi River during this sampling period. The catch data west of the River indicated that the highest brown shrimp catch rate was 10.9 lb/hr of 71-count shrimp at 29°12.8' N. lat. and 93°35.9' W. long., in 9 fm. The highest white shrimp catch rate was 1.6 lb/hr of 10-count shrimp at 29°28.6' N. lat. and 92°55.9' W. long., in 7 fm. The highest pink shrimp catch rate was 0.6 lb/hr of 19-count shrimp at 29°01.2' N. lat. and 92°43.0' W. long., in 13 fm. The highest finfish catch rate west of the River was 242 lb/hr reported at 29°28.6' N. lat. and 92°55.9' W. long., in 7 fm, with Atlantic bumper being the predominant finfish species.

The catch data for Texas indicated that the highest brown shrimp catch rate was 38 lb/hr of 86-count shrimp at 29°12.5' N. lat. and 94°52.6' W. long., in 5 fm. The highest white shrimp catch rate was 29.7 lb/hr of 19-count shrimp at the same location. The highest pink shrimp catch rate was 13.0 lb/hr of 31-count shrimp at 28°55.2' N. lat. and 94°05.1' W. long., in 11 fm. The highest finfish catch rate for Texas was 1,492 lb/hr reported in 5 fm at 29°12.5' N. lat. and 94°52.6' W. long., with Atlantic croaker being the predominant finfish species.
