SEAMAP Red Snapper Real-time Plots |
| The following pdf file contains plots
describing research trawl effort and catch rates for juvenile red snapper
(Lutjanus campechanus) during the SEAMAP Fall Shrimp/Groundfish
Survey in the Gulf of Mexico, October 12 - December 5, 2002. The overall
sampling strategy of the survey is to work from the eastern Gulf to the
Texas/Mexico border. Alabama, Mississippi, Louisiana, Texas and the
National Marine Fisheries Service sampled 367 trawl stations and 59
plankton stations during the survey. The NOAA Ship OREGON II and R/V
TOMMY MUNRO sample offshore and inshore Gulf waters with 40-ft trawls.
Alabama's R/V VERRILL samples offshore Alabama waters with 40-ft trawls.
The R/V PELICAN samples both Louisiana state waters and offshore waters
with 40-ft trawls, and five Texas vessels sample Texas state waters and
offshore waters with 20-ft trawls. Survey areas and station locations are
depicted in Figure 1. Average catch per unit effort (number/hour) within
10 minute blocks of latitude and longitude, standardized to number of
individuals caught per hour for a 40ft trawl, are presented in Figure 2.
Average catch per unit effort (pounds/hour) within 10 minute blocks of
latitude and longitude are presented in Figure 3. Young red snapper taken
during this survey were primarily young-of-the-year. This fishery-independent
data summary is the fourth in the series of such reports for red snapper
and is provided for the use and information of fishery biologists, the
fishing industry, and other interested parties. If you would like more information
