The HUFAs and other nutrients are rapidly metabolized
bye the nauplii (they are racing to get past the first
moults so they can eat!). This starts the moment that
percieve they have been wet. bbs are at their best right
after they have hatched---unless you can get your fry to
eat the decapsulated bs.
With every moult they become less usefull till they can
eat. Then their guts can be loaded with spirulina
etc...(the supplent of your choice). Then they can be
very useful again however, they are then too big for
small (newly hatched) fry.

If your eggs are hatching within in 48 hours then the
bbs are still good for another 12 to 24 hrs in theory.
If you have a look you will be able to see if the bbs
have moulted or not (there is a visible change in
shape). If they mostly have then it may be a good idea
to seive them and only take the newly hatched bbs for
the new borns and the rest given to older fry whose diet
can be supplemented.
On average bbs are good food regardless of age. While
their is a massive degredation in quality they still
maintain alot of useful nutrients.

I'm too lazy to use my spell checker.
