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 ...
