Stability analysis of periodic Fox production models
(Applied Mathematics Institute, University of Alberta, 2006)
In this paper we introduce a nonlinear Fox surplus production model in a periodic environment. The existence and stability of the periodic solutions of nonautonomous nonlinear differential equation (A) are analyzed. ...
Harvesting fisheries management strategies with modified effort function [pre-print]
In traditional harvesting model, a fishing effort, E, is defined by the fishing intensity and does not address the inverse effect of fish abundance on the fishing effort. In this paper, based on a canonical differential ...
Stability of a time-varying fishing model with delay [pre-print]
We introduce a delay differential equation model which describes how fish are harvested (see Abstract Equation Image). In our previous studies we investigated the persistence of the equation and existence of a periodic ...
