Macro zooplankton length-weight equations

Description

Length-weight equations for macro zooplankton to be used for biomass conversions. The equations relate length in mm to dry mass in milligrams. Dry mass can be converted to carbon mass by assuming 40 Uye, S. 1982. Length-weight relationships of important zooplankton from the Inland Sea of Japan. Journal of the Oceanographical Society of Japan 38:149–158.
