Abstract: A process for preserving and storing nematodes having an increased feeding value for later use as needed in the feeding of aquaculture organisms. In this process, nematodes are enriched with an additive such as essential fatty acids, vaccines, hormones, immunostimulants, attractants, nutrients and pigments. Liposomes can serve as a medium for feeding the additives to the nematodes. The enriched nematodes are then desiccated by inducing a quiescent anhydrobiosis (dehydration) and stored for off-the-shell use as needed. When required for feeding, the desiccated enriched nematodes are rehydrated and fed to the aquaculture organisms.
