Evaluating the impact of spatio-temporal scale on CPUE standardization

Chinese Journal of Oceanology and Limnology, 2013
This study focused on the quantitative evaluation of the impact of the spatio-temporal scale used in data collection and grouping on the standardization of CPUE (catch per unit effort). We used the Chinese squid-jigging fishery in the northwestern Pacific Ocean as an example to evaluate 24 scenarios at different spatio-temporal scales, with a ...

The positive effects of typhoons on the fish CPUE in the South China Sea

Continental Shelf Research, 2014
Due to the logistical difficulties associated with fish data sampling after typhoons, short-term effects of typhoons on fishery in the South China Sea (SCS) have not been well-understood. The present study is to evaluate the impacts on the fish catch per unit effort (CPUE) owing to the three typhoons Chanthu, Vicente, and Kai-tak in the northwestern ...

Standardisation of commercial CPUE

Fisheries Research, 2001
Abstract A model for standardisation of fishing power for individual vessels in a commercial fishing fleet is developed. Catch rates of vessels are compared when they are fishing close together in time and space, and their fishing power relative to a standard vessel is calculated.

Fitting fisheries models to standardised CPUE abundance indices

Fisheries Research, 2003
Abstract The observation error method of fitting fisheries models to abundance indices is described. The effects of differing within year coefficients of variation between individual abundance indices are investigated. Likelihoods which are specifically designed to be used with standardised abundance indices estimated from catch and effort data when ...

Demographics and Clinical Characteristics of Patients With CPUE

Journal of Clinical Gastroenterology
Goals: This study examines the demographic and clinical characteristics of patients with CPUE (colonic polyposis of unknown etiology) to determine who may benefit from increased surveillance. Background: CPUE refers to individuals with 10 or more colonic adenomas with no ...

An Experimental and Statistical Approach to the Question: Is CPUE an Index of Abundance?

Canadian Journal of Fisheries and Aquatic Sciences, 1986
Catch per unit effort (CPUE) is often assumed to be an index of stock abundance. Here we present an experiment and a general model for testing this assumption. We used the submersible Pisces IV to make visual estimates of reef-fish density in the Strait of Georgia, British Columbia. These density estimates were compared with CPUE estimates obtained by
