Tristan powerboat CPUE efficiency

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.

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 ...

GLM-standardised rock lobster (Jasus tristani) vessel CPUE at Tristan

2022
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 2017 seasons.

Improving comparisons between models for CPUE

Fisheries Research, 2009
In a recent article published in this journal, Shono (2008) discuss an issue of great relevance in fisheries: how to model catch per unit effort (CPUE). CPUE data are non-negative and severely skewed right, suggesting gamma or log-Normal models. However, often no fish are caught, which produces exact zeros in the data and neither a gamma or log-Normal ...
