Abstract

Coral reef fisheries are of great importance both economically and for food security,
but many reefs are showing evidence of overfishing, with significant ecosystem level
consequences for reef condition. In response, ecological indicators have been
developed to assess the state of reef fisheries and their broader ecosystem-level
impacts. To date, use of fisheries indicators for coral reefs has been rather piecemeal,
with no overarching understanding of their performance with respect to
highlighting fishing effects. Here, we provide a review of multispecies fishery-independent
indicators used to evaluate fishing impacts on coral reefs. We investigate
the consistency with which indicators highlight fishing effects on coral reefs. We
then address questions of statistical power and uncertainty, type of fishing gradient,
scale of analysis, the influence of other variables and the need for more work to set
reference points for empirical, fisheries-independent indicators on coral reefs. Our
review provides knowledge that will help underpin the assessment of the ecological
effects of fishing, offering essential support for the development and implementation
of coral reef fisheries management plans.
