Decapsulated Brine Shrimp Eggs. Hydrate them or just toss them in the tank?

I have Decapsulated brine shrimp eggs from another site(Sorry Cory). The directions say to rehydrate them and then feed them to marine or freshwater fish. I only have fresh water tanks. Is there any need to rehydrate them? I imagine they will rehydrate in the tank just fine. Maybe fish eat them dry and then the food hydrates would that be bad?    

Thanks!

Decapsulated Artemia nauplii are often mixed with a brine solution + aeration for ca. 12-16 hrs. and  the cysts actually _hatch_ into live brine shrimp. It just occurs much faster.

There may be some practice of feeding the decapsulated shrimp right away too. In that case, I assume the concern is just about softening the serving for tiny fry.

Interesting. These are listed as non-hatching I could always experiment with hatching them.
