Catch-per-unit-effort: which estimator is best? [PDF]
Brazilian Journal of Biology, 2010 In this paper we examine the accuracy and precision of three indices of catch-per-unit-effort (CPUE). We carried out simulations, generating catch data according to six probability distributions (normal, Poisson, lognormal, gamma, delta and negative ...

Modeling of Lake Malombe Annual Fish Landings and Catch per Unit Effort (CPUE) [PDF]
Forecasting, 2021 Forecasting, using time series data, has become the most relevant and effective tool for fisheries stock assessment. Autoregressive integrated moving average (ARIMA) modeling has been commonly used to predict the general trend for fish landings with ...

Analysis of the tendency of catch per unit effort in the mexican Pacific sailfish fishery
Ciencias Marinas, 1994 Information from the logbooks of the longline fleet operating under Mexican flag from 1980 to 1990 was analyzed to determine the tendency of the catch per unit effort (CPUE) of the sailfish fishery. Multivariate analysis techniques (principal components

Catch per unit effort and some water quality parameters of Lake Kalgwai Jigawa state, Nigeria. [PDF]
Food Sci Nutr, 2018 AbstractThis study investigated the catch per unit effort and water quality of Lake Kalgwai Jigawa state, Nigeria for the period of 10 month (July 2012‐June 2013). The man hours, gears used, and fish catches of the Lake was determined by assessing the fishermen operating on three major landing sites of the Lake, namely Marke (Site I), Dingare (Site II),

Fishery knowledge-guided machine learning for spatial prediction of catch-per-unit-effort
Ecological IndicatorsCatch per unit effort (CPUE) is a key indicator of fish stock abundance. However, CPUE estimates derived from fishery logbooks are highly susceptible to noise and missing entries, leading to systematic bias in abundance estimation. To address this issue,

Calibrating minimum counts and catch‐per‐unit‐effort as indices of moose population trend
Wildlife Society Bulletin, 2016 Monitoring wildlife population trends often involves indices assumed to correlate in proportion to abundance. We used aerial count data and harvest statistics for moose (Alces alces) populations in 16 hunting districts of Montana, USA, spanning 32 years (

ESTIMATION OF CATCH PER UNIT EFFORT OF FISHERS: A CASE STUDY IN HILONGOS LEYTE, PHILIPPINES [PDF]
Scientific Papers Series : Management, Economic Engineering in Agriculture and Rural Development, 2021 This study estimates the catch per unit effort (CPUE) among fishers in Hilongos, Leyte, Philippines. The identified efforts included in the study were fishing expenses, the presence of companions in fishing activity, fishing hours in a day, fishing days ...

Does harvest of the European grayling, Thymallus thymallus (Actinopterygii: Salmoniformes: Salmonidae), change over time with different intensity of fish stocking and fishing effort? [PDF]
Acta Ichthyologica et Piscatoria, 2020 Background. The European grayling, Thymallus thymallus (Linnaeus, 1758), is a fish species of high value in recreational fishing. The monitoring of changes in grayling populations is a high priority in fisheries.
