Stated preference choice experiment data were collected in 2012 from Massachuestts saltwater recreational fishermen. Saltwater anglers fishing in Massachusetts (MA) waters who obtained a 2012 saltwater recreational fishing permit during the first four months of 2012 were elgible for participation in the study. Potential survey respondents were drawn randomly each month beginning in February and ending in May of 2012. The study consisted of three separate sample groups. The first consisted of 700 anglers who received dichotomous choice contingent valuation mail questionnaires designed to elicit hypothetical WTA measures of the value of its licenses. A second sample group of 700 anglers received questionnaires developed to obtain hypothetical WTP valuations. For the third sample group we simulated an actual market for fishing licenses by offering 500 anglers cash in return for giving up their 2012 fishing license. In total, 1,900 questionnaires were mailed to anglers who obtained a license during the first four months of 2012 and 1,225 surveys were completed for an overall response rate of 64%.
