Comparison between the unexploited system from figure 2 (dashed lines) and one with industrial fishing on life histories with (a) an asymptotic size smaller than 0.5 kg, or (b) ecosystem-wide fishing. Solid lines: normalized size spectra: Nc(F)/Nc(F = 0); dotted lines: resource. Fishing mortality is 0.35 yr−1 (grey lines) and 0.70 yr−1 (black lines).
