Harnessing fishery independent indicators to aid management of data-poor fisheries: weighing habitat and fishing effects
State indicators, e.g., mean size and trophic level of the fish assemblage, can provide importantinsights into the effects of fishing on ecosystems and the resource potential of the fishery. On coral reefs, few studies have examined the relative effects of fishing and other drivers, such as habitat, on these indicators.In light of habitat heterogeneity and increasing habitat degradation, this lack of understanding limits the usefulness of indicators for monitoring the effect of fishery management actions. Identifying thresholds or nonlinearities in relationships between fishing pressure and state indicators has been suggested as a basis for biomass-based targets to support management efforts in low research capacity contexts.
