Efficacy of Using Data from Angler‐Caught Burbot to Estimate Population Rate Functions
Abstract The effective management of a fish population depends on the collection of accurate demographic data from that population. Since demographic data are often expensive and difficult to obtain, developing cost‐effective and efficient collection methods is a high priority. This research evaluat...
