Re: [Killietalk] moina, Japanese daphnia



Paul,

Moina are indeed smaller than other daphnia, but the adults are much larger that baby brine shrimp. The newly "hatched" Moina may well be smaller than bbs, but I know of no way to harvest them. It is possible to put some Moina adults in a fry tray with modest numbers of fry, which can eat the baby Moina as they are produced, but I think that any significant number of fry will consume more than are produced.

In other words, I don't think Moina will allow us to do away with hatching brine shrimp.

Has anyone ever tried raising the daphnia, moina?  They are very small in
size, a smidge smaller than brine shrimp.  They are excellent food for
annual killie fry.  I hear that the Asians use them for food for fry.  It
sounds also that they would be cheaper and more economical than buying
brine shrimp.  One can raise thousands in a one gallon container and do
this the entire year without much trouble.  They are easier to raise than
raising magna daphnia.  They are very nutritious - just think you can feed
these daphnia all sorts of good foods (carrots, peas, yeast, whole wheat
flour - all mixed with water and only a few drops a day will produce a lot
of daphnia.  And all the time and money you will save from hatching out
brine shrimp.  Or you could use brine shrimp as an extra nutritious food.
Just think, these little critters will even multiply in the fry tank.  You
will never have to worry about overfeeding.
I thought that I would bring this to your attention.  You may want to try
them as good food for you killies.
   Sincerely,
Bro. Paul
