A Species persistence, defined as the ratio of surviving vs initial species count in a food web at the start of harvest; B Food-web biomass change, excluding harvested species, defined as the summed harvested biomass divided by the summed pristine biomass for non-harvested species in a food web; (C) Sustained total revenue, defined as the sustained revenue sum of all three fisheries; (D) Sustained total biomass catch, defined as the sum of biomass caught by all three fisheries and; (E) Overall effect indicator, defined as the mean of all self-scaled indicators. Each dot represents one food web. The dashed line at x = 0.5 is given for reference. The systematic linear patterns visible are a result of whether the middle species harvested is closer in trophic level to the smallest species (lower edge) or closer to the largest species (upper edge) (See Supplementary Fig. S15 for a visualisation of this effect).
