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.

Comparison of catch per unit effort of invasive European green crab (Carcinus maenas) across four bait types

, 2020
Restoration of marine ecosystems impacted by invasive, non-native species usually depends on reducing the density of the invader through a targeted cull.

The development of spatio-temporal models of fishery catch-per-unit-effort data to derive indices of relative abundance

, 2020
Spatio-temporal models are increasingly used to develop indices of population abundance from fishery-dependent and –independent data. Developments in spatio-temporal index standardization were discussed at a workshop hosted by The Center for the ...

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 standardization using spatio-temporal models for Australia’s Eastern Tuna and Billfish Fishery

ICES Journal of Marine Science, 2019
The majority of catch per unit effort (cpue) standardizations use generalized linear models (GLMs) or generalized additive models (GAMs). We develop geostatistical models that model catch locations as continuous Gaussian random fields (GRFs) and apply ...

Using Frequency Distributions of Catch per Unit Effort to Measure Fish‐Stock Abundance

Transactions of the American Fisheries Society, 1983
Abstract 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 ...

A comparison of methods for calculating Catch Per Unit Effort (CPUE) of gill net catches in lakes

Fisheries Research, 2008
Abstract 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, 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.

Factors influencing three-spined sticklebackGasterosteus aculeatus(Linnaeus 1758) catch per unit effort

Journal of Applied Ichthyology, 2015
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.
