Evaluation Performance of Three Standardization Models to Estimate Catch-per-Unit-Effort: A Case Study on Pacific Sardine (Sardinops sagax) in the Northwest Pacific Ocean

Fishes, 2023
Catch-per-unit-effort (CPUE) standardization in fisheries is a critical foundation for conducting stock assessment and fishery conservation. The Pacific sardine (Sardinops sagax) is one of the economically important fish species in the Northwest Pacific ...

Relationships of catch-per-unit-effort metrics with abundance vary depending on sampling method and population trajectory.

PLoS ONE, 2020
Catch-per-unit-effort (CPUE) is often used to monitor wildlife populations and to develop statistical population models. Animals caught and released are often not included in CPUE metrics and their inclusion may create more accurate indices of abundance.

Compatibility of the hake model with the longline CPUE data

, 2022
CPUE data for the longline fishery for hake (which are not used in the model-fitting) are superimposed on the corresponding Reference case model-predicted values. Though agreement is reasonable in many instances, it is a concern that the most recent data are much lower than the model predicted values in a number of cases.

Generalized linear Bayesian models for standardizing CPUE: an application to a squid-jigging fishery in the northwest Pacific Ocean

Scientia Marina, 2011
Generalized linear Bayesian (GLBM) non-hierarchical and hierarchical models were developed for standardization of catch per unit effort (CPUE). The GLBM containing the covariates of month, latitude, sea surface temperature (SST), sea surface salinity ...

A multivariate statistical analysis to determine catch intention in the pink cusk-eel (Genypterus blacodes) longline fishery in southern Chile

Scientia Marina, 2020
The definition of catch intention in multispecies fisheries is a key step toward building abundance indexes based on commercial fishing data. Previous analysis to determine catch intention in the pink cusk-eel (Genypterus blacodes) has been based on the ...

GLM-standardised lobster vessel CPUE at Tristan

, 2021
A GLM method is described which is used to standardise the vessel CPUE data at Tristan. The vessel CPUE provides a more optimistic indication of stock status than the powerboat CPUE for the last three seasons. The 2018-2019 vessel GLM 2020 values are slightly above the Jtar target CPUE value, whereas the 2018-2019 powerboat GLM values are slightly ...

Estimation of the maximum sustainable yield of giant grenadier Albatrossia pectoralis (Macrouridae) in the Russian Far East using Bayesian surplus production model JABBA

Известия ТИНРО, 2023
Statistical estimates for the exploitable stock of giant grenadier are determined, by fishing zones in the Russian Far East, and interannual dynamics of the species biomass is considered using historical data on catches and abundance.

Characterization of the dolphinfish (Coryphaenidae) fishery of the United States western north Atlantic Ocean

Scientia Marina, 1999
Fishery dependent data from various commercial and recreational sampling programs form the basis for characterizing the fishery for dolphinfish (Coryphaenus hippurus) in the waters of the Gulf of Mexico and off the southeastern U.S. coast.

Features of distribution and efficiency of saury fishery in dependence on oceanographic conditions in the South-Kuril Region on data of satellite observations in August-November of 2002-2014

Известия ТИНРО, 2017
Oceanographic conditions influence on saury fishery in the South-Kuril Region is considered on the SST satellite data and fisheries information obtained in August-November of 2002-2014. The SST spatial distribution patterns are compared between the years
