Functions to allow fisheries managers to simulate a bus route creel survey

This repository is no longer current. It will be kept in place because a question on refers to this repository, functions, and .Rd files, but this repository will not be updated. Please see the repository AnglerCreelSurveySimulation for the most updated version of this package.

===== Creel surveys allow fisheries scientists and managers the ability to sample anglers in a fishery and achieve statisticaly-valid estimates of catch rate, harvest rate, and in some cases, fish populations. Depending upon the size of the fishery, creel surveys can be challenging to implement correctly. Further, creel surveys can be costly. Much research has been spent on identifying methods for creel surveys. However, relatively little research time has been spent on answering the question what is the best creel-survey type to implement in my fishery? The package(s) and code contained in this repository include functions to allow fisheries managers the ability to simulate a creel survey with a priori data.

This package has been submitted to CRAN for publication on 4 Jan 2015. A manuscript is in progress for publication in the Journal of Statistical Software.

Additional information: meanTripLength and catchRate are estimated from the gamma distribution The Ratio of Means is used to estiate catch and effort (Malvestuto 1996; Jones and Pollock 2012) Creel surveys can be estimated as a 'one-off' or bus route-type surveys (e.g., multiple stops along a route) Simulations can be run to estimate >= 1 surveys * Resulting values for estimated catch and estimated effort can be plotted as a function of true catch and true effort to evaluate how accurately the survey reflects reality.
