Allocating Sampling Effort to Equalize Precision of Electrofishing Catch per Unit Effort [PDF]

North American Journal of Fisheries Management, 1998
We used a spatially explicit simulation model to examine the effects of lake shoreline length and lakewide fish density on electrofishing catch-per-unit-effort (CPUE) estimates of fish density.

The need for spatio-temporal modeling to determine catch-per-unit effort based indices of abundance and associated composition data for inclusion in stock assessment models

Fisheries Research, 2020
We describe and illustrate a spatio-temporal modelling approach for analyzing age- or size-specific catch-per-unit-effort (CPUE) data to develop indices of relative abundance and associated composition data.

Catch-per-unit-effort: which estimator is best? [PDF]

Brazilian Journal of Biology, 2010
In this paper we examine the accuracy and precision of three indices of catch-per-unit-effort (CPUE). We carried out simulations, generating catch data according to six probability distributions (normal, Poisson, lognormal, gamma, delta and negative ...

Target-based catch-per-unit-effort standardization in multispecies fisheries [PDF]

Canadian Journal of Fisheries and Aquatic Sciences, 2018
Standardized catch per unit effort (CPUE) is a fundamental component of fishery stock assessment. In multispecies fisheries, catchability can differ depending on which species is being targeted, and so the yearly trend extracted from the standardized ...

Catch Per Unit Effort (CPUE) of Bivalves in Northwestern Bohol, Philippines

International journal of Rural Development, Environment and Health Research, 2019
: Catch Per Unit Effort (CPUE) is a measure of status of marine resource in a given area. In this study, bivalve fishery information was gathered using the self-structured questionnaire.

Catch per Unit Effort Dynamic of Yellowfin Tuna Related to Sea Surface Temperature and Chlorophyll in Southern Indonesia

Fishes, 2020
Tuna fisheries are the most valuable fisheries in the world, with an estimated market value of at least US$42 billion in 2018. Indonesia plays an important role in the global tuna fisheries and has committed to improve its fisheries management; therefore,

Evaluation of the impacts of different treatments of spatio-temporal variation in catch-per-unit-effort standardization models

Fisheries Research, 2019
Many stock assessments heavily rely on indices of relative abundance derived from fisheries-dependent catch-per-unit-effort (CPUE) data. Therefore, it is critical to evaluate different CPUE standardization methods under varying scenarios of data ...

Gill net catch composition and catch per unit effort in Flag Boshielo Dam, Limpopo Province, South Africa

Water SA, 2017
Gill net surveys were conducted in 2013 to determine species composition and fisheries potential of Flag Boshielo Dam. Species contributing the most towards total biomass were Labeo rosae (40%), Oreochromis mossambicus (15%), Schilbe intermedius (10 ...

Large differences in catch per unit of effort between two minnow trap models [PDF]

BMC Research Notes, 2013
Background Little is known about variation in catch per unit of effort (CPUE) in stickleback fisheries, or the factors explaining this variation. We investigated how nine-spined stickleback (Pungitius pungitius) CPUE was influenced by trap model by ...
