Figure 2From: Dynamical analysis of a stochastic toxin-producing phytoplankton–fish system with harvestingThe global asymptotical stability of the positive equilibrium \(E_{*}(3.8, 0.55)\) in deterministic system (1). (a) Time series diagram. (b) Phase diagram. The parameters are \(\alpha=0.8\), \(\beta =0.6\), \(\gamma=4\), \(\rho=0.5\), \(d_{2}=0.8\), \(d_{1}=0.2\), \(\mu_{1}=0.8\), \(r=1.5\), \(h_{1}=0.3\) and \(h_{2}=0.8\)Back to article page
