Atomic C:N ratios in calanoid copepods were generally below the Redfie
ld ratio (6.6), except for the fifth copepodid stage of Calanus sp. Th
e C:P ratios in copepods were generally close to, or higher than the R
edfield ratio of 106, but low C:P ratios were found in Acartia clausi
(63 +/- 7) and in the cladocerans (Podon sp.: 34 +/- 5 and Evadne sp.:
59 +/- 22).
