 For illustration the panels E and F are included in See Figure 3.10. Biomass over time (lines) for ‘large piscivores’ in the Gulf of Thailand. ''P/B'' is the production/biomass ratio (equals ''Z'', the total mortality) for the group, while v is the vulnerability setting describing how the group interacts with each of its prey groups.  Dots represent CPUE from surveys." to show the effect of using a high vulnerability (v=100) for the interactions between the large piscivores and each of its prey groups. It is apparent that this does not result in any improvement in fit between model and CPUE, but in fact in the opposite. The best fit in the example is thus obtained using the parameter settings of panel D.

 '''Figure 3.9''' The solid line shows the predicted mortality calculated as Z ·B, and the dotted line the population growth estimated as a function of the consumption. The area between the lines can be considered ‘surplus production’.
