Contrasting stock status trends obtained from survey and fishery CPUE, taking Larimichthys polyactis in Yellow Sea Large Marine Ecosystem as an example

open access: yesEcological Indicators, 2023
Biological conservation of exploited fish species involves characterizing key aspects of their population dynamics using models as tools to estimate their biomass. The Bayesian state-space surplus production model in the open-source stock assessment tool

Application of the Tweedie distribution to zero-catch data in CPUE analysis [PDF]

open access: yesFisheries Research, 2008
Abstract We focus on the zero-catch problem of CPUE (catch per unit effort) standardization. Because the traditional CPUE model with a log-normal error structure cannot be applied in this case, three methods have often been utilized as follows: (1) Ad hoc method adds a small constant value to all response variables.

CPUE as an index of relative abundance for nearshore reef fishes

open access: yesFisheries Research, 2006
Using density measurements derived by SCUBA diving, we have verified that research angling catch per unit of effort (CPUE) is a useful measurement of the relative abundance of nearshore reef species when the appropriate habitat is targeted. We found a strictly proportional relationship between lingcod and copper rockfish CPUE and density using a ranged

CPUE retrieval from spaceborne lidar data: A case study in the Atlantic bigeye tuna fishing area and Antarctica fishing area

open access: yesFrontiers in Marine Science, 2022
The measurement of Catch Per Unit Effort (CPUE) supports the assessment of status and trends by managers. This proportion of total catch to the harvesting effort estimates the abundance of fishery resources.

The accuracy of capture per unit effort in predicting density of a cryptic snake was more sensitive to reductions in spatial than temporal coverage. [PDF]

open access: yesPLoS ONE
A critical component of monitoring wildlife populations is understanding changes in population size or abundance. However, for most populations a complete census is not possible; thus, trends or abundance need to be estimated through alternative means ...

Fish species composition and catch per unit effort in Nong Han wetland, Sakon Nakhon Province, Thailand [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2020
A study on fish species composition and catch per unit effort (CPUE) was conducted at the Nong Han wetland in Sakon Nakhon Province, Thailand. Fish were collected with 3 randomized samplings per season at 6 stations using 6 sets of gillnets. A total of

Tristan powerboat CPUE efficiency

open access: yes, 2022
This document aims to inform on how certain important factors related to the Tristan powerboat CPUE data could influence the recent CPUE trend. Here we explore the influence the individual fisherman may have on the annual CPUE index.

Catch Efficiency of Multi-Mesh Trammel Nets for Sampling Freshwater Fishes

open access: yesFishes, 2023
A multi-mesh trammel net has been developed and used for sampling freshwater fishes. However, little is known about the catch efficiency of the net. This research investigated the catch efficiency of a multi-mesh trammel net (nominal mesh size; 10.0, 30 ...
