  abstract = {{W}e present the first representative and quantified overview of the indices used worldwide for assessing the biodiversity of coral reef fishes. {O}n this basis, we discuss the suitability and drawbacks of the indices most widely used in the assessment of coral fish biodiversity. {A}n extensive and systematic survey of the literature focused on coral reef fish biodiversity was conducted from 1990 up to the present. {W}e found that the multicomponent aspect of biodiversity, which is considered as a key feature of biodiversity for numerous terrestrial and marine ecosystems, has been poorly taken into account in coral reef fish studies. {S}pecies richness is still strongly dominant while other diversity components, such as functional diversity, are underestimated even when functional information is available. {W}e also demonstrate that the reason for choosing particular indices is often unclear, mainly based on empirical rationales and/or the reproduction of widespread habits, but generally with no clear relevance with regard to the aims of the studies. {A}s a result, the most widely used indices (species richness, {S}hannon, etc.) would appear to be poorly suited to meeting the main challenges facing the monitoring of coral reef fish biodiversity in the future. {O}ur results clearly show that coral reef scientists should rather take advantage of the multicomponent aspect of biodiversity. {T}o facilitate this approach, we propose general guidelines to serve as a basis for the selection of indices that provide complementary and relevant information for monitoring the response of coral reef fish biodiversity in the face of structuring factors (natural or anthropic). {T}he aim of these guidelines was to achieve a better match between the properties of the selected indices and the context of each study (e.g. expected effect of the main structuring factors, nature of data available).},
