1. History of the Marine Recreational Fisheries Statistical Survey (MRFSS) in the United States Virgin Islands (USVI)
U.S. Virgin Islands Marine Recreational Information (MRIP) Program Workshop September 10-12, 2012
Southeast Regional Office
Sustainable Fisheries /Caribbean Branch
St. Petersburg, Florida

2. Background
Most species of fish in estuarine and inshore areas, as well as many in open waters, are harvested jointly by recreational and commercial fishermen.
Catches by the marine recreational fishery are a significant portion of the total landings of many marine species.
Passage of the Magnuson Fishery Conservation and Management Act in 1976 mandated collection of data for both commercial and recreational marine fisheries.

3. Background
NOAA Fisheries Glossary – MRFSS is an annual national survey conducted by the NMFS, in cooperation with the coastal states, to estimate the number, catch, and effort of recreational fishermen.
Implemented nationally in 1979 (except in Alaska) as mandated by the Sustainable Fisheries Act.
Following several years of testing, a standard method of data collection and statistical estimation was initiated in 1981

5. The MRFSS Program History in the USVI
: The MRFSS program was conducted in the U.S. Caribbean by personal interviews at individual homes, rather than by telephone surveys.
Insufficient funds caused the MRFSS program sampling to be discontinued in the U.S. Caribbean.
1986 – The USVI Department of Fish and Wildlife (DWF) carried out a telephone survey to evaluate the efficacy of the telephone sampling technique. The survey:
tried to collect fisheries data for the recreational non-charter boat fishery around the USVI .
found that telephone surveys by themselves may provide biased data on recreational fishing in the USVI.
concluded that mail surveys and limited creel surveys should
supplement the phone surveys.

6. The MRFSS Program History in the USVI Cont.
1999 – NOAA Fisheries and the USVI DFW reinitiate efforts to collect recreational data in the U.S. Caribbean.
1999 – In December, telephone sampling is reinitiated in the USVI as telephone ownership rates appeared adequate .
2000 – In March, intercept sampling begins in USVI.
2001 – Data collection stops.

7. Difficulties with Implementing the MRFSS Program in the USVI
Difficulty in recruiting, hiring, and retaining intercept samplers in the U.S. Caribbean, especially in the USVI, apparently because there is not much interest within the population for this type of part-time work.
Low efficiency because many fishing access sites are characterized by very low activity, making it more difficult and expensive to obtain samples.
Subsistence fishing is not being captured by the MRFSS program.

8. Difficulties with Implementing the MRFSS Program in USVI
In both PR and the USVI, there were problems in getting interviewers to report back in a timely fashion and to send in completed data forms.
Inexperience of the interviewers, especially with respect to identifying anglers to interview and convincing those anglers to submit to an interview.
More recent data information on household populations and phone ownership needs to be available. Data on household populations by island in the USVI is needed to improve sampling.

9. Revised Methodology (MRFSS to MRIP)
Traditional MRFSS:
Estimates from the Access Point Angler Intercept Survey (APAIS) were calculated using unweighted data that did not reflect the complex sampling design and contained some intercepts that were not obtained through probability sampling.
The resulting MRFSS estimates were design-biased and have been criticized by both the National Research Council (2006) and constituents.
To address this issue, several changes were made as part of the new MRIP APAIS estimation method:
First and foremost, a design-based method for estimating catch rate from the APAIS data was developed to calculate new MRIP estimates.
Additionally, all non-probability convenience sample data, previously included in the MRFSS APAIS, has been eliminated from MRIP APAIS estimation.
Lastly, a statistical adjustment has been applied to account for the fact that only a fraction of all the anglers were being observed at a selected site during a sampled day.
This improved method has been used to calculate revised Atlantic and Gulf coast catch and effort estimates back through Revisions have not yet been made for the U.S. Caribbean (Puerto Rico).
