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 ...

Characterizing fishing effort and spatial extent of coastal fisheries. [PDF]
PLoS ONE, 2010 Biodiverse coastal zones are often areas of intense fishing pressure due to the high relative density of fishing capacity in these nearshore regions.

Mapping Fishing Effort through AIS Data. [PDF]
PLoS ONE, 2015 Several research initiatives have been undertaken to map fishing effort at high spatial resolution using the Vessel Monitoring System (VMS). An alternative to the VMS is represented by the Automatic Identification System (AIS), which in the EU became ...

Optimal fishing effort benefits fisheries and conservation [PDF]
Scientific Reports, 2021 The ecosystem effects of all commercial fishing methods need to be fully understood in order to manage our marine environments more effectively. The impacts associated with the most damaging mobile fishing methods are well documented leading to such ...

Seasonal variability in global industrial fishing effort.
PLoS ONE, 2019 Human beings are the dominant top predator in the marine ecosystem. Throughout most of the global ocean this predation is carried out by industrial fishing vessels, that can now be observed in unprecedented detail via satellite monitoring of Automatic ...

The Social Aspects of Fishing Effort
Human Ecology, 2007 While economic literature inspired by the “tragedy of the commons” has emphasised people’s tendency to increase fishing effort beyond desirable levels, sociologists and anthropologists who have studied the social aspects of fishing have often emphasised the capacity of these factors to restrict fishing effort.

Optimal spatial distribution of the fishing effort in a multi fishing zone model
Ecological Modelling, 2006 This work presents a stock-effort dynamical model of a fishery subdivided on several fishing zones. The stock corresponds to a fish population moving between different zones, on which they are harvested by fishing fleets. The bio-economical model is a set of ODE’s governing the fishing efforts and the stocks on the different fishing zones.

Recreational fishing effort and how management actions can affect it—Part 1: Theory
EDIS, 2023 Recreational fishing is especially important to Florida’s economy and ecosystems. One of the most important metrics of recreational fisheries is “effort”—defined as the number of trips taken during a time and place.

Estimating fishing effort from highly resolved geospatial data: Focusing on passive gears
Ecological Indicators, 2023 Increasing competition for marine space requires the appropriate development of indicators to best represent the use of marine areas and the value (whether economic, social and/or cultural) derived from such use.
