Simulate an angler population, sample the simulated population with a user-specified survey times, and calculate metrics from a bus route-type creel survey.
Functions to allow fisheries managers to simulate a bus route creel survey
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.
