Imputation of missing count data of recreational boat retrievals from remote camera surveys in the Perth Metropolitan region, Western Australia
Abstract
In Western Australia (WA), remote cameras have been used to monitor boating activity at boat ramps since 2006 to assist in ongoing recreational fishing surveys. These monitoring schemes are useful tools to validate boating activity (defined here as the number of retrievals) and to corroborate estimates of recreational fishing effort obtained from other surveys. This is because remote cameras (also referred to as digital cameras) can provide complete coverage (i.e. 24 hours, 365 days) of boating activities. However, although efforts are continually made to service and maintain these cameras, outages (i.e. interruptions in camera operations) have been encountered and continue to occur. To provide accurate estimates of boating activity, an imputation process is required to adequately account for these gaps in the remote camera data.
