Statistical Models for Estimating CPUE from Catch and Effort Data
Canadian Journal of Fisheries and Aquatic Sciences, 1992Catch-per-unit-effort (CPUE) provides one of the most commonly used abundance indices in fishery research. The literature, however, offers no unique method of estimating CPUE and its variance from catch and effort data. In this paper we develop two models (univariate and bivariate) that generalize previous approaches and remain valid under management ...

A multispecies approach to subsetting logbook data for purposes of estimating CPUE
Fisheries Research, 2004Abstract An initial step in catch and effort analysis is determination of what subset of the data is relevant to the analysis. We propose an objective approach to subsetting trip records of catch and effort data when fishing locations are unknown; the species composition taken on a fishing trip is used to infer if that trip's fishing effort occurred ...

A re-analysis of the squid jig CPUE data
2006The catch per unit effort (CPUE) indices from the squid jig fishery have to date been expressed in terms of catch per man-hour (Roel, 1998). Industry has for many years questioned the use of man-hours as the unit of effort since it is alleged that the information contained in the database regarding the number of hours fished is unreliable.

Coastal community CPUE standardization in the Galician Small-Scale Fishery
2015No abstracts are to be cited without prior reference to the author.Small-scale fisheries (SSFs) are usually under-attended despite being a large contributor to globalcatches, and of relevance for local economies and society. This is in part due to the paucity ofappropriate information preventing the assessment and management of key species.

Analysis of CPUE data time-series for Latvian fishing fleet.
2013No abstracts are to be cited without prior reference to the author. Latvian fishery in the Baltic Sea is based on three main species – cod, sprat and herring. Sprat is one of the most abundant and commercially important fish species for Latvian fishermen. Sprat landings during 2000-2012 contributed about 60% to total Latvian catch.

Nominal longline CPUE from Gough and Nightingale lobster fisheries
2008This document reports the nominal longline CPUE values available for Gough and Nightingale Islands from the summary sheet records. Exponential trends are fitted to the more recent data, and estimates of the annual rate of increase are presented.

GLM and GLMM standardisation of the commercial abalone CPUE for Zones A-D
2012This paper presents an update of the standardisation of the abalone CPUE using the conventional GLM approach and adding new data for the 2010/2011 fishing in Zones A and B. A GLMM approach to standardising abalone CPUE data is also investigated.
