RE: Daphnia, baker yeast and sugar & Confused Flour Beetles
Thanks Duane,
As I am a Daphnia challenged individual I really appreciate your input. I
have experimented with the 2 liter bottle method and just as I was about to
get lots of daphnia poof the culture died off. I have green water and I am
adding about 1.5 quarts of the stuff per day to my 10 gal daphnia tank and I
get a few dozen daphnia every day to feed to my fish. So far the culture has
been up for a few weeks and at least it has not crashed but a few dozen
daphnia per day make for a great appetizer for about 1% of my fish. But I
will consider trying yeast etc. I heard rabbit food pellets (alfalfa work a
treat too).
I hatched a few hundred hungry Nothos a few weeks ago. I have burned up
about a dozen white and grindle worm cultures harvesting about 50% either
daily or every other day. The cooler weather has not helped either.
I was hoping for help from the daphnia. But so far there has not been much
help there. Maybe 10 gal tanks are just too small.
I am supplementing with frozen BS and frozen blood worms. But I prefer live
foods.
I currently have
White worms
Grindle worms
Microworms
vinegar eels
Confused Flour beetles
daphnia/moena/cyclopse/osteocod mix
red worms
green water
paramecium
But I could use another high production food animal for Notho size fish. The
large fruit flies I had were not worth the bother as many of my fish would
not surface feed for them and/or they climbed up onto floating plants. Is
there anything I am missing which could produce a high volume of live food
at little cost in a small space?
Best regards,
~RJ~

RJ, I have a daphnia culture that has been producing very well for the last
three years and I`m sure that there are others out there that been up for
much longer than that. My success is directly related to the information in
the Plankton Culture Manual from Florida Aqua Farms. I`ve mentioned this
before on this list and I do not benefit in any way from these people, they
just have a terrific publication for any one who is interested in live food
for their fish. They state that Moina is the easiest to culture as it`s
requirements are more flexible, temp etc. My tank is in the basement , it`s
a Rubbermaid Rough Tote, 50 gal. that measures 42x21x16in. deep but don`t
get one of these, mine leaks. I can only maintain 7-8 in of depth and it
would be best at 12-15 in., but still I have what you might call an
automatic water change system of sorts. I have 2- 2 tube shop lights right
down on top of the tank that are on 14 hr. a day to supply algae, also I
have a continuous culture o!
f algae
that I add every day when I feed. The food is Fleischmann`s Active Dry
Yeast, 1/2 tsp in 8 0z. of RO water plus 1/8 tsp of sugar, 4 oz. a day seems
to support the culture as over feeding is a big problem that can cause
crashes. I add at the same times about a cup of the algae culture. Since the
water leaks down to a given point, I add the change water from my Diapteron
tanks about twice a week as they are unheated the same as my Daphnia tank. I
think that a good supply of algae is a must and they state that fact in
their publication. That`s what I do, it works for me. Regards, Duane
