SEAMAP Real-time Plots for the year 2000

Week 2

This is the second data summary of catch rate information from the 2000 SEAMAP Summer Shrimp/Groundfish Surveys in the northern Gulf of Mexico. This week's summary includes sampling from June 13 through June 18 by the NOAA Ship OREGON II east of the Mississippi River and sampling from Texas vessels from June 1 through June 13. 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 east of the River indicated that the highest brown shrimp catch rate was 12.8 lb/hr of 38-count shrimp at 29°18.2' N. lat. and 88°51.5' W. long., in 25 fm. The highest catch rate of white shrimp east of the River was 7.2 lb/hr of 21-count shrimp at 29°18.0' N. lat. and 88°57.7' W. long., in 12 fm. The catch data east of the River indicated that the highest pink shrimp catch rate was 9.5 lb/hr of 28-count shrimp at 29°57.9' N. lat. and 88°11.4' W. long., in 16 fm.

The highest finfish catch rate east of the River was 1,365 lb/hr reported in 30 fm at 29°25.5' W. lat. and 88°03.7' W. long., with longspine porgy being the predominant finfish species.

The catch data west of the River indicated that the highest brown shrimp catch rate was 4.3 lb/hr of 108-count shrimp at 29°35.5' N. lat. and 93°50.9' W. long., in 4 fm. The highest catch rate of white shrimp west of the River was 6.6 lb/hr of 22-count shrimp at 29°38.3' N. lat. and 93°02.8' W. long., in 3 fm. No pink shrimp were caught west of the River.

The highest finfish catch rate west of the River was 124 lb/hr reported in 6 fm at 29°33.5' W. lat. and 93°52.3' W. long., with gulf menhaden being the predominant finfish species.

The catch data for Texas indicated that the highest brown shrimp catch rate was 21.4 lb/hr of 69-count shrimp at 25°59.5' N. lat. and 97°05.5' W. long., in 10 fm. The highest catch rate of white shrimp in Texas was 8.5 lb/hr of 20-count shrimp at 29°25.6' N. lat. and 94°36.4' W. long., in 4 fm. The catch data for Texas indicated that the highest pink shrimp catch rate was 8.5 lb/hr of 52-count shrimp at 25°59.5' N. lat. and 97°05.5' W. long., in 10 fm.

The highest finfish catch rate west of the River was 357 lb/hr reported in 7 fm at 29°19.6' W. lat. and 94°40.4' 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 Texas offshore waters by the OREGON II and Texas' vessels and waters off Mississippi by the TOMMY MUNRO.
