Figure 4From: Stochastic optimization model of aquacultured fish for sale and ecological education The extinction time \(\pmb{T_{\mathrm{ex}}}\) computed with the optimal opening time \(\pmb{\tau^{*}}\) in the \(\pmb{\alpha^{ ( 1 )}}\) - \(\pmb{\alpha^{ ( 2 )}}\) 2-D parameter space. The grey line corresponds to \(T_{\mathrm{ex}}\) with \(\tau^{*} = 52\) (day).Back to article page
