Validating Matches of Electronically Reported Fishing Trips to Investigate Matching Error

Recently, researchers have developed methods for combining probability samples and non-probability samples. In recreational fisheries management, data from probability samples are typically counts of catch from a random sample of trips intercepted by …

The Impact of Nonsampling Errors on Estimators of Catch from Electronic Reporting Systems

The National Marine Fisheries Service is the agency charged with estimating the number of fish removed from US oceans by recreational anglers. Two surveys produce data for these estimates; one measures number of angler trips and the other fish caught …
