Evaluating the value of the Internet for the collection of scientific data (use, harvest and attitudes) from anglers


January 2012 - December 2014


Fishery managers have long recognized the need for and value of human dimensions information for managing the fisheries resources. Collecting good scientific data representative of the angling population is very expensive and takes months to collect and analyze. However, recent advances in computer technology and widespread use of the Internet by the public have generated considerable interest in using Internet-based survey methodology. The main advantages of using the Internet are speed and cost savings. However, two major factors that reduce the validity of Internet-based survey methodology are non-response bias and sample validity resulting from incomplete coverage of the target population. The main objective of this study is to identify the nature and extent of these two possible sources of bias and develop a relatively inexpensive process to correct biases associated with an Internet survey.
