  abstract = {{T}rophic level ({TL})-based indicators have been widely used to examine fishing impacts in aquatic ecosystems and the induced biodiversity changes. {H}owever, much debate has ensued regarding discrepancies and challenges arising from the use of landings data from commercial fisheries to calculate {TL} indicators. {S}ubsequent studies have started to examine survey-based and model-based indicators. {I}n this paper, we undertake an extensive evaluation of a variety of {TL} indicators across 9 well-studied marine ecosystems by making use of model- as well as survey- and catch-based {TL} indicators. {U}sing detailed regional information and data on fishing history, fishing intensity, and environmental conditions, we evaluate how well {TL} indicators are capturing fishing effects at the community level of marine ecosystems. {O}ur results highlight that the differences observed between {TL} indicator values and trends is dependent on the data source and the {TL} cut-off point used in the calculations and is not attributable to an intrinsic problem with {TL}-based indicators. {A}ll 3 data sources provide useful information about the structural changes in the ecosystem as a result of fishing, but our results indicate that only model-based indicators represent fishing impacts at the whole ecosystem level.},
