Aponogeton fruit

My Ap. sp. (crispus x something, probably) has flowered and fruited.  There are
about 50 fruiting bodies on an inflorescence about 25 cm long.  In my
terrestrial plant experience, fruiting bodies are highly correlated with
fertile seeds, but I know NOTHING about Aps.

How should these fruits (which fertilized and developed underwater) be treated?
 Dried and opened?  Kept moist?  Cooled?    Please advise.  Dave
