  • Description:
    "The Puget Sound Recreational Shellfishing Survey was administered in 2013 by the Northwest Fisheries Science Center to enable the estimation of changes in economic value associated with biotoxin- and pollution-related clam and oyster harvest closures in Puget Sound, Washington. In particular, data were collected in order to estimate econometric models of recreational demand. This Technical Memorandum describes the methodology used to administer the survey and some of the basic findings, including characteristics of harvest trips and harvester preferences, expenditures, and demographics. The survey was administered by mail, but included a telephone screener to identify license holders who had actively harvested clams or oysters in Puget Sound within the previous 12 months. Answers from this short telephone screener were also compared to answers from the mail survey to identify potential nonresponse bias. We found very little evidence of differences between respondents to the telephone screener and those who completed the mail survey. Clam and oyster harvesting in Puget Sound appears to be a regular, important recreational activity for many respondents. Respondents reported an average of 3.7 and 2.4 days harvesting clams and oysters, respectively. These harvesting days translated into a significant number of meals, as more than half of the respondents consumed at least four meals per year containing their harvest, with 18% consuming more than ten meals per year. Only 30% of Puget Sound clam and oyster harvesters also harvested razor clams on ocean beaches. Respondents also indicated that they would continue to take harvesting trips in the future, with more than half stating they would definitely harvest within the next 12 months and only 1% indicating that they would definitely not harvest. Most harvesters (64%) tended to use a single beach exclusively. Even harvesters who used more than one beach tended to use beaches that were in close proximity to one another. This suggests a unique importance at the individual harvester level for individual beaches, and clusters of beaches, across Puget Sound. These data provide shellfish managers with useful information about current harvesters. Future work will use these data to estimate models of recreational demand, in order to estimate the changes in economic value that result from changes in harvest closures"--Executive Summary.
