In blue growth under map (25): Panel (a) µ = 1.5; Panel (b) µ = 0.2; Panel (c) µ = 0.05. The dashed line represents biomass X, and the solid black line is harvesting. Staircase diagram of trajectory starting at X0 = 4 is in magenta. Staircase diagram of trajectory starting at X0 = 3 is in cyan. Staircase diagram of trajectory starting at \(X_0=6.5\) is in gray. Equilibria are intersections between the curve of growth and the dashed line and are spotted by a black dot. Parameters are a = 0.9; ψ = 1.2; \(r=1.5a/\psi\); K = 4 and η = 1
