摘要：

Efficiency of hand sorting versus centrifugally floating benthic samples of high detritus composition was compared. Centrifugal flotation removed a large proportion (up to 90%) of the detritus, significantly increased recovery of several taxa (e.g. copepods, mites and chironomids), and decreased overall sorting time. Centrifugal flotation was effective for both live and preserved samples and was 3 to 10 times more efficient than hand sorting.
