Summary of biomass variations as a function of fishing selectivity and intensity when target size is (a) log₁₀(w_f/w₀) = 2 or (b) log₁₀(w_f/w₀) = 4. The x-axis spans fishing intensity measured by expected catch C₀ that is, the catch that would be produced by applying the fishing effort to the unfished spectrum (C₀ is used to calculate the fishing mortality multiplier a). The y-axis spans fishing selectivity s. Each bar shows: minimum (dark grey), median (light grey), and maximum (black) biomass (over simulated years 130–150). Median biomass ≈0.07 g m⁻³ for C₀ = 0.00125. Empty cells correspond to total extinction of biomass in the system.
