Length-Dry Weight Relationships of Some Freshwater Zooplankton^a

Abstract

Abstract Biomass of zooplankton can be estimated from the relation between length and weight by measuring the appropriate dimension of length on individual zooplankton. Length-dry weight relationships for 15 species of freshwater crustacean zooplankton collected from the Connecticut River were determined. Length-weight equations can be used to rapidly determine the biomass of zooplankton species when it is impractical to directly measure their weights.
