Fish grabbing: Weak governance and productive waters are targets for distant water fishing.

open access: yesPLoS 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 ...

Feedback control and its impact on generalist predator–prey system with prey harvesting

open access: yesNonlinear 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.
