Abstract
A comparison of diary and mail methodologies for a cohort of anglers who fished Lake Ontario was used to examine biases associated with 12-month recall from mail questionnaires. Significant differences in estimates were found between estimates reported by respondents in diaries (1992) versus mail questionnaires (1991) for number of days fished and fish consumption, but not for fishing expenditures and catch. After the data were adjusted for a decline in fishing on Lake Ontario between 1991 and 1992, it was found that angler-days were overestimated by 44–45% on the 12-month recall mail questionnaire. This percentage can serve as an initial estimate of a correction factor for future studies. Lower average annual fish consumption rates were reported in the diary year compared with the mail questionnaire year. However, because of the lower percentage of meals of sport-caught fish during the diary year and the knowledge that sportfishing declined in 1992 for Lake Ontario anglers, it is not clear what ...Keywords
