Abstract
As a sustainable method of farming, ecological aquaculture aims to balance economic benefits and maintain biodiversity. Reasonable breeding strategies can reduce resource waste and sustain the persistent survival of populations. In this paper, we present a novel ecological aquaculture model with impulsive harvesting and nonlinear releasing larval predators at different fixed moments. The global stability of the prey-vanishing periodic solution and the permanence of system are analyzed by theory of impulsive differential equations. In addition, the existence conditions for positive periodic solutions are obtained through bifurcation theory. Finally, our findings are verified through numerical simulations.
期刊介绍：
Computational Science is a rapidly growing multi- and interdisciplinary field that uses advanced computing and data analysis to understand and solve complex problems. It has reached a level of predictive capability that now firmly complements the traditional pillars of experimentation and theory.
The recent advances in experimental techniques such as detectors, on-line sensor networks and high-resolution imaging techniques, have opened up new windows into physical and biological processes at many levels of detail. The resulting data explosion allows for detailed data driven modeling and simulation.
This new discipline in science combines computational thinking, modern computational methods, devices and collateral technologies to address problems far beyond the scope of traditional numerical methods.
Computational science typically unifies three distinct elements:
• Modeling, Algorithms and Simulations (e.g. numerical and non-numerical, discrete and continuous);
• Software developed to solve science (e.g., biological, physical, and social), engineering, medicine, and humanities problems;
• Computer and information science that develops and optimizes the advanced system hardware, software, networking, and data management components (e.g. problem solving environments).
