Electrofishing eel, salmon and trout: impact of waveform and frequency on capture-per-unit-effort and spinal damage

Knowledge and Management of Aquatic Ecosystems, 2020
Performing fish survey protocols with different electrofishing equipment and settings can lead to difficulties in comparing the data obtained. In this study, we captured two fish taxa (i.e. the European eel and salmonids: Atlantic salmon and brown trout)

Fishing Effort and Associated Catch per Unit Effort for Small-Scale Fisheries in the Mozambique Channel Region: 1950–2016

Frontiers in Marine Science, 2021
The Mozambique Channel region in East Africa has diverse marine ecosystems and serves as a migratory corridor for economically important species. Local and foreign industrial fisheries operate in the Mozambique Channel, but regional small-scale fisheries

REPORT OF THE WORKSHOP ON MODELLING CATCH-PER-UNIT-EFFORT (WKCPUE)

, 2021
Standardized Catch-Per-Unit-Effort (CPUE), i.e., data from commercial fisheries that have been statistically modelled to remove fishery dependant effect, are often used in stock assessments as indicators of abundance and biomass. Here we report the outcomes of the workshop on modeling CPUEs that took place virtually on the 3-5 November 2020 and 6-7 ...

Regional and gendered patterns in Madagascar’s small-scale fisheries

Frontiers in Marine Science
Small-scale fisheries play an essential role in supporting food security and economic resilience in Madagascar’s coastal communities. These fisheries are diverse, ranging from offshore net and line fishing, often dominated by men, to nearshore gleaning ...

Analyse des statistiques de pêche aux engins dans le bassin du Rhône. Deuxième partie : étude des captures

Knowledge and Management of Aquatic Ecosystems, 1993
En confrontant les captures déclarées et les autorisations délivrées sur le Rhône et la Saône en 1988 et 1989, on estime pour ces deux années les prélèvements de la pêche aux engins à 238 t/an et 273 t/an. Les captures sont essentiellement constituées de

Temporal and seasonal influences concerning the carbon footprint of pelagic fisheries [PDF]

Global Journal of Environmental Science and Management
BACKGROUND AND OBJECTIVES: Pelagic fisheries play a vital role in sustaining coastal livelihoods and food security in the Eastern Indian Ocean, yet they also contribute to greenhouse gas emissions due to fuel-intensive operations.

STANDARDIZATION OF CATCH‐PER‐UNIT‐EFFORT FOR SHORT‐TERM TRENDS IN CATCHABILITY

Natural Resource Modeling, 1987
Examination of daily catch–per–unit–effort (CPUE) information on Pacific halibut revealed sharp declines that could not be explained by natural and fishing mortality. Catchability may have decreased during a fishing period because of local depletions of fish, changes in fish behavior, and other causes.

Coarse woody habitat use by local fish species and structural integrity of enhancements over time in a shallow northern boreal lake assessed in a Bayesian modelling approach

Ecological Solutions and Evidence, 2023
The introduction of coarse woody habitat has been a widely adopted management practice for restoring and enhancing freshwater aquatic ecosystems. Although responses of aquatic fish and invertebrate communities have largely been documented for lotic ...
