Abstract

We studied the effect of a developing Skeletonema marinoi/Phaeocystis spp. bloom on Calanus finmarchicus hatching success, early naupliar survival and metabolism. Our focus was (1) on the development of reproductive rates during a bloom initiation, peak and decline in relation to the production of potentially toxic algal metabolites and (2) on the proportional importance of female nutrition versus naupliar food environment for the production of viable nauplii. Despite polyunsaturated aldehyde (PUA) production by both S. marinoi and Phaeocystis sp., we did not observe any harmful effects on hatching success or naupliar survival and condition in any stages of the short-term (<1 week) algal bloom. Hatching success appeared to be controlled by egg lipid composition, while the beneficial effect of a high food concentration was reflected in naupliar RNA: DNA ratio, protein content and total production of viable nauplii. The egg lipids reflected seston lipids, indicating that the egg fatty acid composition was not modified by the females. Our results suggest that unselective feeding and/or retention of specific lipids can induce qualitative food limitation, although recruitment during the S. marinoi/Phaeocystis sp. bloom was high.
