Abstract
AbstractPlacing preserved animals in the wide arm of a fluid-filled U-shaped open tube provides an accurate linear measure of biomass. Changes in fluid level are monitored by projecting an image of the tube into a dissecting microscope equipped with an ocular micrometer. Precision of the calibration curves is equivalent to length–weight regressions. However, only a single curve need be generated to predict wet weight of many taxa. Separate calibration curves are required to predict dry weights of hard- and soft-bodied taxa. The instrument is not suitable for measuring biomass of living individuals.
