Comparing three indices of catch per unit effort using Bayesian geostatistics
Fisheries Research, 2009In assessing a fish stock, indices based on catch per unit effort (CPUE) are frequently used. Estimates of three indices of catch per unit effort were compared here (CPUE1, CPUE2 and CPUE3), considering the fitting of two models: (i) a bivariate geostatistical model for catch and effort; (ii) a bivariate model where catch and effort were considered ...

CATCH PER UNIT EFFORT FOR MOOSE: A NEW APPROACH USING WEIBULL REGRESSION
Journal of Wildlife Management, 2005Abstract The relationship between hunters and their environment is a key component in managing wildlife populations. Identifying hunter's characteristics, motivations, and efforts is crucial to understanding if a hunt will be successful. We predicted that landscape characteristics and moose (Alces alces) densities would affect success of hunts.

A comparison of methods for calculating Catch Per Unit Effort (CPUE) of gill net catches in lakes
Fisheries Research, 2008Abstract Fish constitute an important component of lake ecosystems and many different methods have been used for fish assessment. Based on gill net catches in two stratified (max depth = 14–22 m) eutrophic Danish lakes, relative fish abundance measured as Catch Per Unit Effort (CPUE) was calculated.

Catch per unit effort trends in the coastal fishery of Manzanillo, Colima, Mexico
Fisheries Management and Ecology, 1997The catch per unit effort (CPUE) values, expressed as kg trip–1 in a coastal fishery, were considered to be an index of resource abundance to explain changes through time. The trends in catch and effort for three commercial landing sites in Manzanillo and Santiago Bays in Colima, Mexico, were analysed for the period November 1982 to May 1991.

Relation of "Catch per Unit Effort" to Abundance and Rate of Exploitation
Journal of the Fisheries Research Board of Canada, 1940Two extreme types of fisheries are set up for analysis. In type I natural mortality and recruitment are negligible while fishing is in progress; in type II natural mortality, recruitment and fishing mortality all occur throughout the year at a uniform rate.

Summary Different types of fishing gear are known to vary in catch per unit effort (CPUE), but little is known regarding this in respect to the three-spined stickleback Gasterosteus aculeatus (Linnaeus 1758). The influence of the three-spined stickleback CPUE by trap model, baiting and visual attractors was investigated.

Using Frequency Distributions of Catch per Unit Effort to Measure Fish-Stock Abundance
Transactions of the American Fisheries Society, 1983Abstract Mean catch per unit effort often is used as an index of fish abundance, N. This index is often biased. Frequency distributions of catch per unit effort (C/f) and independent estimates of N from a headboat sport fishery for yellowtail snappers Ocyurus chrysurus off Islamorada, Florida, indicated that mean C/f underestimated changes in N ...

Abstract While catch per unit effort (CPUE) is the most widely used metric for expressing and comparing boat electrofishing catch data, “effort” has been inconsistently defined. Boat electrofishing guidelines refer to both time- and distance-based metrics, with little consensus about the appropriateness of one over the other.

Comparison of Two Methods of Combining Catch-Per-Unit-Effort Data from Geographic Regions
Canadian Journal of Fisheries and Aquatic Sciences, 1982We examined two methods of combining catch-and-effort data from small geographic regions into large regulatory areas to estimate catch-per-unit-effort (CPUE): (1) weighting regional CPUE by bottom area occupied by the population; (2) weighting by fishing effort.
