Egg yolk: what's the particle size?

[Mean_Chlorine]

Often one hear the suggestion to use boiled egg yolk as feed for
egglayer fry, e.g. by dipping it in water and squeezing out "juice"
through a fine cloth.
However, I can find no estimate on the size of the particles produced.
It's obviously very small, but how small? Does anyone know
approximately what size particles you get with "egg-yolk-juice"?

IMO, Does it actually matter? Taking into account that egg-yolk is very
soft, I think that counts more than what size would. Its really how
'available' the food is to the fry. Obviously the smaller and softer the
particle size is the better. I'm sure that even if a big piece (compared to
the fry) were to be used they would still have access to it as it will be
soft and eventually small flakey particles would be available from the
bigger piece. This would be havoc on water quality though! Unless of course
you're a compulsive water changer :)
Would'nt it be less bother to just culture some 'green water'? Or plop in an
algae covered rock?

I gotta agree with happycamper. Green water is better and safer.
If you OD on egg yolk it goes bad REALLY quickly and will kill
your fry.
Baby brineshrimp is also a fav of fry. You can get powdered fry foods
too

Yes, it does if you're trying to feed young mussels.

Well you should have said so, you mentioned fry so I thought that in context
of your message...
Maybe you can put some egg yolk into a syringe mixed with tank water, shake
it all around and 'target feed' the mussel with the syringe?
