| Abstract |
Newly released ephyrae of the scyphomedusa Cyanea capillata did not grow on either Artemia nauplii or copepod dominated mixed zooplankton, but grew with an average rate of 16.5 % day -1 (maximum of 30.6 % day -1 ) with a ctenophore as food. The two first food types did not generate medusae with normal development of tentacles and oral arms over a seven-week period, whereas the ctenophore food did. We suggest that availability of gelatinous prey for newly released ephyrae is a bottleneck in the development, making constraints on the population succession and at least partly explaining interannual variations in abundance of C. capillata. |
