. In a postal survey of 13750 anglers holding licences for a variety of waters in South Wales, a response rate of 51‐8% was achieved. Reasons for non‐response bias were investigated. Response rates varied throughout the 13‐month study, suggesting response was enhanced by prior publicity and in winter, but reduced in the summer holiday period. There was also a progressive loss of potential respondents through deaths and relocation. Salmon anglers provided a higher response rate than trout and coarse anglers. Anglers who had purchased a season licence gave a higher response than those holding a short‐term licence. Receipt of questionnaires mid‐week produced a lower rate of response. Young and infrequent anglers are likely to be underrepresented in a postal sample. The importance of such non‐response bias to parameters estimated by the survey such as catch, expenditure or fishing frequency is discussed. Recommendations are made for increasing response in future surveys.
