Angler Characteristics and Management Implications in a Large, Multistock, Spatially Structured Recreational Fishery

Abstract

Management of recreational fisheries involves understanding how anglers interact with the fishery resource. Managers must understand the source (spatial distribution), efficiency, and behavior of angler effort in order to develop optimal management strategies in a social–ecological framework. We interviewed anglers (n = 1,956) and assessed fish populations in 21 lakes that are part of a multistock, spatially structured fishery for Rainbow Trout Oncorhynchus mykiss in the interior of British Columbia, Canada. Our objective was to assess the spatial behavior, harvest behavior, and catch efficiency of anglers and to understand the strengths of interactions between anglers and fish populations in three regions within this large fishery. Our results suggest a diverse angler population that varied in its behavior and its impact on the fishery. Using a hierarchical cluster analysis, we identified four distinct angler groups based on three variables that directly described how anglers interacted with the fishery (spatial distribution, catchability, and harvest behavior). Angler characteristics varied between groups, and the relative proportions of the four discrete angler groups varied among management regions. Substantial variation in angler characteristics across groups and variation in the relative distribution of the groups across regions imply that a “one size fits all” management approach is not optimal for this fishery. Instead, strategies that are attuned to angler characteristics would constitute a better approach for managing this large, spatially structured fishery.Received April 18, 2012; accepted March 10, 2013

Smartphones Reveal Angler Behavior: A Case Study of a Popular Mobile Fishing Application in Alberta, Canada

“…Our finding that anglers visited lakes that were within a reasonable driving distance of large population centers is nothing new; it is consistent with conventional data from Alberta and well established in the literature (e.g., Post et al 2008;Ward et al 2013). However, the fact that we observed angler preferences (and movement networks) by applying fairly basic analyses to data from the uncoordinated use of an app that was not developed for research demonstrates the enormous potential of this technology.…”

Imputing recreational angling effort from time-lapse cameras using an hierarchical Bayesian model

“…; Johnston et al, 2010) and fish species (Post et al, 2002). Managing these fisheries is challenging due to the complex inter-dependence of management options, population dynamics and the distribution of anglers (Cox et al, 2003;Parkinson et al, 2004;Post et al, 2002Post et al, , 2008Ward et al, 2013b). The quantity of angling effort is often used by managers to evaluate the success of various management options (Lester et al, 2003;Parkinson et al, 1988;Shuter et al, 1998).…”
