SEAMAP Real-time Plots for the year 2003
This is the third preliminary data summary for the 2003 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from June 16 through June 22 by the OREGON II and Texas vessels. Catch data from the OREGON II were taken with a 40-ft trawl. Catch data from the Texas vessels were taken with 20-ft trawls.
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.
The catch data west of the Mississippi River indicated that the highest brown shrimp catch rate was 2.6 lb/hr of 80-count shrimp at 29°38.5' N. lat. and 93°46.8' W. long., in 5 fm. The highest white shrimp catch rate was 0.8 lb/hr of 23-count shrimp at 29°40.5' N. lat. and 93°45.9' W. long., in 5 fm. No pink shrimp were caught west of the River during this sampling period. The highest finfish catch rate west of the River was 167 lb/hr reported in 6 fm at 29°37.6' W. lat. and 93°36.9' W. long., with trout being the dominant finfish species.
The catch data for Texas indicated that the highest brown shrimp catch rate was 108.1 lb/hr of 79-count shrimp at 27°49.9' N. lat. and 96°44.1' W. long., in14 fm. The highest white shrimp catch rate was 32.8 lb/hr of 18-count shrimp at 27°47.6' N. lat. and 97°01.8' W. long., in 7 fm. The highest pink shrimp catch rate was 236.8 lb/hr of 93-count shrimp at 26°09.3' N. lat. and 97°02.2' W. long., in 12 fm. The highest finfish catch rate for Texas was 1,465 lb/hr reported at 27°47.6' N. lat. and 97°01.8' W. long., in 7 fm., with Atlantic croaker being the dominant finfish species.Back to 2003
