Predicting Catch-Per-Unit-Effort Using Semantic Trajectories and Machine Learning

, 2020
This work presents a framework for the prediction of catch-per-unit-effort (CPUE)—an important index in the assessment of fisheries resource exploitation—using three data sources from the North Adriatic region: fishing vessel tracking data (obtained from

Efficiency of fishing gears in the river Halda, Chittagong, Bangladesh

Journal of Fisheries, 2015
To determine the catch efficiency of fishing gears, catch per unit effort (CPUE) data were collected for two years during January 2007 to December 2008 from the river Halda.

Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Catch per unit of effort (CPUE) variation and sustainability of artisanal fishing in relation to environmental variables in Colombian Pacific

, 2023
Contextualization: artisanal fishing in the Colombian Pacific is positioned as one of the main sources of income for the communities settled on the coasts, therefore, there is strong pressure on fishing resources, with non-selective fishing gear such as the trammel netting and the hand linehook, capturing individuals that have not presented ...

Performance of Lacustrine Protected Areas (LPAs) on Lake Victoria: A Case of Bulago, Uganda

Aquaculture, Fish and Fisheries
The Bulago Lucustrine Protected Area (LPA) was established on Lake Victoria, Uganda, as a sanctuary for severely depleted fish stocks, a breeding and spawning ground and a biodiversity conservation zone. Despite its ecological importance, no studies have

Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea

Journal of Fish Biology, EarlyView.
Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

Journal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

Comparing three indices of catch per unit effort using Bayesian geostatistics

, 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 (CPUE(1), CPUE(2) and CPUE(3)), considering the fitting of two models: (i) a bivariate ...

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Use of different approaches to model catch per unit effort (CPUE) abundance of fish [PDF]

, 2016
Fish catch rates are expressed as Catch Per Unit Effort (CPUE) which is a performance index representing the success of fishing from commercial fishery statistics.
