Catch composition, catch per unit effort (CPUE) and species selectivity of fishing gears on multi-species Kaptai Lake in Bangladesh [PDF]
HeliyonKaptai Lake, the largest artificial reservoir in Southeast Asia, is home to a diverse fish fauna that supports thousands of livelihoods and is distinguished by multi-species and multi-gear fisheries.

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

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.

Allocating Sampling Effort to Equalize Precision of Electrofishing Catch per Unit Effort [PDF]
North American Journal of Fisheries Management, 1998 Abstract We used a spatially explicit simulation model to examine the effects of lake shoreline length and lakewide fish density on electrofishing catch-per-unit-effort (CPUE) estimates of fish density. We also tested model predictions regarding the influence of shoreline length and fish density on precision of CPUE estimates by analyzing ...

On the standardization of the fishing effort [PDF]
Acta Amazonica, 2000 In this note we demonstrate that the use of an index to standardize the fishing effort using the cpue of a standard vessel or gear is mistaken, once the cpues- catch per unit of total effort after standardization is similar to cpues - catch per unit of ...
