SEAMAP Real-time Plots for the year 2003

Week 2

This is the second preliminary data summary for the 2003 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling on June 10 by the Alabama Vessel A.E. VERRILL east of the Mississippi River. Catch data from the A.E. VERRILL 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.

Shrimp catches were generally low for this sampling period. The catch data east of the River indicated that the highest brown shrimp catch rate was 8.0 lb/hr of 56-count shrimp at 30°05.9' N. lat. and 88°07.0' W. long., in 14 fm. The highest white shrimp catch rate east of the river was 4.8 lb/hr of 18-count shrimp at 30°08.1'N. and 88°03.3'W in 9 fm. The catch data east of the River indicated that the highest pink shrimp catch rate was 5.8 lb/hr of 28-count shrimp at 29°58.0' N. lat. and 88°08.4' W. long., in 14 fm. The highest finfish catch rate east of the River was 73 lb/hr reported in 18 fm at 29°54.6' W. lat. and 88°08.5' W. long., with no predominant finfish species.
