Figure 8From: Global dynamics in a stochastic three species food-chain model with harvesting and distributed delaysSpecies \(x_{i}(t)\) (\(i=1,2,3\)) are also persistent in the mean. There is an optimal harvesting strategy \(H^{*}=(h_{1}^{*},h_{2}^{*},h_{3}^{*})^{T}=(0.0023,0.1414,0.0958)^{T}\), and the maximum of expectation of sustainable yield (MESY) is \(\frac{Y^{*}(H^{*})}{H_{3}}=0.3464\)Back to article page
