Methods for standardizing CPUE and how to select among them

چکیده
A number of methods for estimating trends in relative abundance based on standardized catch-per-unit-effort (CPUE) are discussed, including general linear and additive models, habitat-based standardization, neural networks, and regression trees. Methods and criteria for testing among various standardization techniques are presented and recommendations for future research are presented. Authors’

Model selection and multimodel inference for standardizing catch rates of bycatch species: a case study of oceanic whitetip shark in the Hawaii-based longline fishery
One key issue for standardizing catch per unit effort (CPUE) of bycatch species is how to model observations of zero catch per fishing operation. Typically, the fraction of zero catches is high, and catch counts may be overdispersed. In this study, we develop a model selection andmultimodel inference approach to standardize CPUE in a case study of oceanic whitetip shark (Carcharhinus longimanus...

Catch per unit efforts and impacts of gears on fish abundance in an oxbow lake ecosystem in Eastern India
Background: Oxbow lakes are abundant in indigenous fishes, but they are subject to unsustainable fishing practices, potential overexploitation, and indiscriminate use of fine-meshed fishing gear. To quantify the catch per unit effort (CPUE) and impact of fishing gears on fish abundance, a survey was carried out in an oxbow lake in eastern India. Methods: The gear-wise CPUE for fish caught in...
