Linking catchability and fisher behaviour under effort management [PDF]
, 2008 Catchability is crucial for the economic performance of fisheries and their management. However, in many bio-economic simulation models it is assumed to be either constant or it is largely ignored, despite the fact that it is known to vary due to ...

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.

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.
