| Outline of Final Research Achievements |
In this subject, we could establish the two followings; 1) the enhancement of cultivation method of the marine copepod which could be a model for the feeding regime in the larviculture of marine finfish, 2) the clarification of feeding effect of cultivated copepod.
We could cultivate the marine copepod continuously in the 50-100L scale and feed them to finfish larvae and juveniles under laboratory condition. When the cultivated copepod was fed to finfish larvae with the rotifers which were used as the general feed for marine finfish larvae, those larvae ingested the copepod selectively.
As the result of fatty acid analysis, copepods included much amount of DHA in polar lipid. When rotifers were enriched DHA amount in the polar lipid modeled the fatty acid composition of copepod, the survival and growth of finfish larvae could be improved.
