Downloads
Documents and data are available for download after the data are declared "final". When downloads are separated by coasts, combined Atlantic and Gulf of Mexico data are annotated with "AG", Gulf-only data with "GU", and Pacific data with "PC". Some downloads may have been produced in the past, but are not currently available.
MRFSS Datasets
MRFSS estimates and survey data are currently available through 2003 and do not include revised estimates produced under the MRIP program.
MRIP Datasets and Template Programs
The MRIP template programs should be used with the MRIP survey datasets. MRIP survey datasets are optimized for use by the MRIP programs, and other files available on our website are not compatible with these programs.
For more information on each type of file, see MRIP Read Me.doc. Variable formats and descriptions can be found in MRIP_Estimates_Variables.xls (estimate dataset variables) or MRIP_Survey_Variables.xls (survey dataset variables).
MRIP Datasets
** UPDATE **
TRIP_YYYYW datasets within PS_YYYYW.zip files were updated on October 24th, 2012. It is recommended that users download the new files and replace previously downloaded files. We have added a few fields and corrected a minor issue with the placeholder records for FHS effort in cells with no intercepted trips. None of the updates should impact point estimates for the primary domains of interest.
Each survey data zip file, PS_YYYY.zip, contains three files per year/wave.
Trip level data (analogous to MRFSS i1 dataset) and variables required for use in estimation. Contains one record per angler-trip interview (identified by id_code).
Catch level data and variables required for use in estimation. Contains one record per species for every angler-trip interview.
Fish level length and weight data and variables required for use in estimation. Contains one record per fish caught and measured or weighed by interviewer.
MRIP Template Programs
MRIP catch estimation for custom domains.
This is a template program for estimating catch totals using the MRIP public-use datasets.
The program is setup to use information in the trip_yyyyw dataset to define custom domains. The catches are estimated within the domains by merging the trip information onto the catch_yyyyw datasets. See program for additional information.
MRIP directed angler-trips (effort) for custom domains.
This is a template program for estimating directed trips using the MRIP public-use datasets.
The program is setup to use trip_yyyyw datasets to define custom domains and estimate total angler-trips within domains. Catch information can be used in defining the domains by merging the catch_yyyyw datasets onto the trip_yyyyw datasets. See program for additional information.
MRIP length frequencies for single species within custom domains.
This is a template program for estimating length frequencies using the MRIP public-use datasets.
The program is setup to calculate length frequencies (in numbers of fish and as proportions) using the size_yyyyw datasets. Custom estimation domains may be defined by merging trip information from the trip_yyyyw datasets onto the size datasets. See program for additional information.
Domain: a defined sub-level, geographic or otherwise, of the stratified estimation design. Typically, these are sub-state geographic divisions based on county groups, or even sampled site groups if the domain cannot be defined by county boarders.
