An attempt was made to measure body length, dry weight and chemical composition of the principal planktonic copepod species in the Cananeia Lagoon estuarine system, Sao Paulo, Brazil. Individual dry weight of the copepods increased logarithmically with increasing body size (prosome and total body lengths), and species-specific regression equations of the length-weight relationships were obtained for Acartia lilljeborgi, A. tonsa, Pseudodiaptomus acutus, Paracalanus crassirostris, P. quasimodo, Temora turbinata, Labidocera fluviatilis, Oithona hebes, O. oswaldocruzi and Euterpina acutifrons. Carbon, nitrogen and hydrogen content of these copepods was 44.2-46.4%, 10.9-12.1% and 6.7-7.2% of dry weight, respectively.
