SEAMAP Real-time Plots for the year 2002


Week 4

This is the fourth preliminary sampling report for June 23 through July 1 by the NOAA Ship OREGON II off the Texas and Louisiana coasts, and sampling from Texas vessels on June 26. 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.

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 26.7 lb/hr of 36-count shrimp at 28°41.3' N. lat. and 93°21.2' W. long., in 17 fm. No white shrimp were caught west of the River during this sampling period. The highest pink shrimp catch rate was 3.1 lb/hr of 23-count shrimp at 28°43.2' N. lat. and 93°53.9' W. long., in 14 fm. The highest finfish catch rate west of the River was 240 lb/hr reported at the same station, with Atlantic bumper being the predominant finfish species.

The catch data for Texas indicated that the highest brown shrimp catch rate was 151.1 lb/hr of 57-count shrimp at 28°36.4' N. lat. and 94°43.4' W. long., in 16 fm. The highest white shrimp catch rate was 52.1 lb/hr of 7-count shrimp at 28°11.9' N. lat. and 96°38.3' W. long., in 5 fm. The highest pink shrimp catch rate was 21.8 lb/hr of 38-count shrimp at 28°46.2' N. lat. and 94°40.3' W. long., in 12 fm. The highest finfish catch rate for Texas was 1,370 lb/hr reported in 7 fm at 28°21.4' N. lat. and 96°20.1' W. long., with Atlantic croaker being the predominant finfish species.
