SEAMAP Real-time Plots for the year 2000


Week 6

This is the sixth preliminary data summary for the 2000 SEAMAP Summer Shrimp/Groundfish Survey in the northern Gulf of Mexico. This week's summary includes sampling from July 9 through July 16 by the NOAA Ship OREGON II off the Louisiana coast. 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.

Only two 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 38.5 lb/hr of 34-count shrimp at 28°46.8' N. lat. and 91°49.4' W. long., in 15 fm. The catch data west of the River indicated that the highest white shrimp catch rate was 1.4 lb/hr of 24-count shrimp at 29°19.6' N. lat. and 92°42.1' W. long., in 9 fm. The catch data west of the River indicated that the highest pink shrimp catch rate was 2.0 lb/hr of 20-count shrimp at 28°59.8' N. lat. and 92°02.3' W. long., in 11 fm.

The highest finfish catch rate west of the River was 522 lb/hr reported in 7 fm at 29°22.4' N. lat. and 93°17.2' W. long., with Atlantic croaker being the predominant finfish species.

We anticipate mailing updated data from the SEAMAP survey every Wednesday. Sampling coverage for the next weekly period will be in Louisiana waters by the R/V PELICAN and TOMMY MUNRO, and offshore Mississippi and Alabama waters by the OREGON II.
