Estimating whole-lake fish catch per unit effort

Fisheries Research, 2015
Abstract The European standard for gillnet sampling to characterize lake fish communities stratifies sampling effort ( i.e. , number of nets) within depth strata. Nets to sample benthic habitats are randomly distributed throughout the lake within each depth strata.

Is catch-per-unit-effort proportional to abundance?

Canadian Journal of Fisheries and Aquatic Sciences, 2001
We compiled 297 series of catch-per-unit-effort (CPUE) and independent abundance data (as estimated by research trawl surveys) and used observation error and random effects models to test the hypothesis that CPUE is proportional to true abundance. We used a power curve, for which we were interested in the shape parameter (β).

Comparing three indices of catch per unit effort using Bayesian geostatistics

Fisheries Research, 2009
In 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, 2005
Abstract 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.

Catch per unit effort trends in the coastal fishery of Manzanillo, Colima, Mexico

Fisheries Management and Ecology, 1997
The 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, 1940
Two 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.
