Predicted relationships between global yield and fishing mortality.

Modelled changes in global yield as a function of F (expressed as a proportion of F_MMSY for all consumers of body mass > 100g) and selectivity. Each column presents results for one selectivity scenario (A to D, Table 3) and panels show yields by consumer for (a) all individuals of any body mass, (b) body mass < 1 kg (small), (c) 1 kg to 10 kg (medium) and (d) > 10 kg (large).
