Fish grabbing: Weak governance and productive waters are targets for distant water fishing.
PLoS ONE, 2022 Distant water fishing occurs worldwide as foreign fleets fish in the exclusive economic zones (EEZs) of other states. We test the hypothesis that host state governance performance is an explanatory factor in observed distant water fishing effort using ...

Changes of the eel fishery patterns in the Vistula Lagoon, Poland [PDF]
Acta Ichthyologica et Piscatoria, 2008 Background. The decline in the eel population is reflected in the decreased incomes of fishers. This has led to changes in the structure and size of the fishing effort. The fyke nets used in eel catches are multi-species gear.

Multiyear tagging studies incorporating fishing effort data [PDF]
Canadian Journal of Fisheries and Aquatic Sciences, 1998 The Brownie models for multiyear tagging studies can be used to estimate age- and year-specific annual survival rates and tag recovery rates. The latter are composites of the exploitation rates and rates of tag reporting, tag shedding, and tag-induced mortality.

Feedback control and its impact on generalist predator–prey system with prey harvesting
Nonlinear Analysis, 2019 This article examines the effectiveness of feedback control as a management policy on a generalist predator–prey system with prey harvesting. We discuss the result of implementing feedback control with respect to prey and predator separately.

Global fishing capacity and fishing effort from 1950 to 2012
Fish and Fisheries, 2016 AbstractGlobal marine wild‐capture landings have remained relatively stable for >20 years; however, there is a lack of credible fishing capacity and effort information required to assess the sustainability and efficiency of the global fleet. As such, we estimated global fishing capacity and effort from 1950 to 2012 using a relatively comprehensive ...
