Northeast Groundfish Recreational demand survey of anglers, ME through NJ

Stated preference choice experiment data were collected in conjunction with NMFS’ Marine Recreational Fisheries Statistics Survey (MRFSS) along the coastal states of Maine through New Jersey during calendar year 2009. All anglers intercepted in Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, and New Jersey for the MRFSS were asked to participate in a voluntary follow-up mail survey. Anglers who agreed to participate in the follow-up were sent mail questionnaires using a modified Dillman Tailored Design. The choice experiment survey asked anglers that have targeted Gulf of Maine cod, haddock, or pollock to simultaneously compare features of different hypothetical fishing trips and then to choose the trip they liked best. The features or attributes varied across trips and included bag and size limits of each species, the number of legal-sized fish caught of each species, the number of sub-legal sized fish caught of each species, the number of other types of fish that were legally kept, the trip length in hours, and the total trip cost. Respondents were also permitted to choose an opt-out option which was “Do something other than saltwater fishing.” The collection of choice responses from the various choice scenarios allows for the examination of tradeoffs and behavioral responses to various biological and regulatory changes. A total of 4,577 surveys were mailed out and 1,491 completed mail surveys were returned for a response rate of 33%.
