SEAMAP Real-time Plots for the year 2001


Week 5

This is the fifth preliminary data summary for the 2001 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from July 11 through July 14 by the National Marine Fisheries Service aboard the TOMMY MUNRO, and sampling from July 11 through July 14 by the OREGON II. Catch data from the TOMMY MUNRO and 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.

The catch data west of the River indicate that the highest brown shrimp catch rate was 12.8 lb/hr of 22-count shrimp at 28°34.9' N. lat. and 92°42.1' W. long., in 20 fm. Pink shrimp catch rates were generally low west of the River. The catch data west of the River indicate that the highest white shrimp catch rate was 0.3 lb/hr of 16-count shrimp at 28°42.1' N. lat. And 90°36.7' W. long., in 9 fm.

The highest finfish catch rate west of the River was 110 lb/hr at 28°53.8' N. lat. And 92°39.4' W. long. in 14 fm. Longspine porgy was the dominant finfish species

The catch data for Texas indicated that the highest brown shrimp catch rate was 178.0 lb/hr of 49-count shrimp at 26°51.5' N. lat. and 97°14.4' W. long., in 13 fm. The highest catch rate of white shrimp in Texas was 0.5 lb/hr of 12-count shrimp at 26°52.4' N. lat. and 97°15.4' W. long., in 12 fm. The catch data for Texas indicated that the highest pink shrimp catch rate was 28.0 lb/hr of 31-count shrimp at 26°58.0' N. lat. and 97°18.6' W. long., in 9 fm.

The highest finfish catch rate off Texas was 380 lb/hr reported in 10 fm at 26°07.3' W. lat. and 97°04.3' W. long.
