Visual census methods underestimate density and diversity of cryptic reef fishes

Research output: Contribution to journal › Article › peer-review

Abstract

The diversity and density of small, benthic reef fishes were estimated using visual census and enclosed rotenone stations. Visual census underestimated the number of species present and the density of common species by up to 91%.
