Marine reserve benefits and recreational fishing yields: The winners and the losers.
Marine reserves constitute effective tools for preserving fish stocks and associated human benefits. However, not all reserves perform equally, and predicting the response of marine communities to management actions in the long run is challenging.

ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

Catch per unit effort (CPUE) and water level variations in the lower reaches of the White Volta River were studied at three landing sites namely, Pataplapei (upstream), Porturto (midstream), and Aglassipei (downstream) from October 2011 to March 2012 to ...

In order to determine the factors governing the spatial distribution of effort, it is essential to better understand the relationship between CPUE and abundance.

Using Catch Data to Estimate Changes in Global Commercial Abalone Abundance
ABSTRACT Changes in global wild capture production of abalone are explored to infer potential changes in biological stocks. The study found that 77% (or 10 out of the 13) of the countries that reportedly caught abalone in the wild have experienced declines in catches between 1980 and 2023, and on aggregate catch declined by almost 83% between 1980 and ...

In this study it is aimed that determining effect of some social and demographic properties on Catch Per Unit Effort (CPUE) in Uluabat Lake anglers. A total of 375 interview applied with angler from April 2015 to May 2016 monthly period. Mean CPUE values of each angler was estimated as 1.36 fish/hr (0.08-5.67).

Estimating whole-lake fish catch per unit effort
The European standard for gillnetsampling to characterize lake fish communities stratifies sampling effort (i.e., number of nets) within depth strata. Nets to sample benthic habitats are randomly distributed throughout the lake within each depth strata.

ABSTRACT Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab (Callinectes sapidus) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections ...

The aim of this study was to determine the exploitation of 7 freshwater species, Freshwater bream ( Abramis brama Linnaeus, 1758), Vimba bream ( Vimba vimba Linnaeus, 1758), Wels catfish ( Silurus glanis Linnaeus, 1758), Roach ( Rutilus rutilus Linnaeus, 1758), European perch ( Perca fluviatilis Linnaeus, 1758), Prussian carp ( Carassius gibelio Bloch,

Comparison between CPUE (vessel-day fishing effort) for individual areas sampled using non-retention and retention techniques. Difference in CPUE was evaluated using a log-linear negative binomial model, rejecting the null hypothesis of no difference ...
