A simple device for culturing marine calanoid copepods is described. Calanus helgolandicus Pacificus, Acartia clausi Giesbrecht, Temora longicornis Muller, and Eurytemora hirundoides Nordquist, were reared in this device. The latter had been bred in the laboratory for several generations. Antibiotics were used only once when the experiment was started. Filtered seawater was used, with a salinity of about 29,5 approx. 0,5 per thousand. Skeletonema costatum, Isochrysis galbana, Chlamydomonas sp., Phaeodactylum tricornutum, Monochrysis sp., and Dunaliella sp. were used as food ( none of the media used was bacteria-free). The effect of temperature on the life cycle of Eurytemora hirundoides has also been studied. |
