Outline of Final Research Achievements |
Feeding activity and egg production in the neritic copepods were investigated using nine microalgae (four dinoflagellates, one cryptophyte, haptophyte, prasinophyte, raphidophyte and diatom) as food. The fatty acid composition of these microalgae was measured, and the intake of each fatty acid in the copepod was also determined. Copepod clutch sizes were increased with increaing an intake of n-3 poly-unsaturated fatty acids, especially, 22:6(n-3) fatty acid (docosahexaenoic acid). Field incubation experiments to examine the feeding activity on microplankton assemblage and the egg production of neritic ccopepod revealed that there was a significant positive correlation between ingestion rate on dinoflagellates/oligotrich ciliates and spwning number of copepods.
