Allocating Sampling Effort to Equalize Precision of Electrofishing Catch per Unit Effort [PDF]
North American Journal of Fisheries Management, 1998 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.

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 ...

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 (

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),

Target-based catch-per-unit-effort standardization in multispecies fisheries [PDF]
Canadian Journal of Fisheries and Aquatic Sciences, 2018 Standardized catch per unit effort (CPUE) is a fundamental component of fishery stock assessment. In multispecies fisheries, catchability can differ depending on which species is being targeted, and so the yearly trend extracted from the standardized CPUE is likely to be biased.

Seasonal Abundance Distribution and Catch Per Unit Effort of Fishes in the Swartkops Estuary [PDF]
South African Journal of Zoology, 1980 Catch per unit effort was obtained for the nekton of the Swartkops estuary near Port Elizabeth by means of gill netting. Fifty gill net catches were made in which 1 269 fish were caught in areas representative of the mouth, middle and upper reaches of the estuary.

Qarun Lake fisheries; Fishing gears, Species composition and Catch per unit effort
Egyptian Journal of Aquatic Biology and Fisheries, 2014 Qarun Lake is a closed salty basin located about 90km southern Cairo Egypt, cover an area of 230km 2 with annual production of about 3000 tonnes. The present study assessed the lake fishery for better management purpose. Data, information and samples were collected through 42 field trips and 311 fishermen interviews during fishing season (2010-2011 ...

Journal of Marine Science and Engineering, 2023 The Makassar Strait (MS) is characterized by water mass from the Pacific Ocean and is one of the ITF (Indonesia Throughflow) branches. It carries warm water masses from the Pacific Ocean to the Indian Ocean. This research aims to analyze the relationship

Growing Into Poverty: Reconstructing Peruvian Small-Scale Fishing Effort Between 1950 and 2018
Frontiers in Marine Science, 2020 Small-scale fisheries are globally marginalized by management institutions; thus, they have to endure the consequences of ineffective regulations, environmental uncertainty, social traps and market inequity.
