Special protist needed

[M.Q.Benedict at iaea.org]

Dear Colleagues,
I am involved in a project that requires development of a living
larval mosquito diet.  Larvae are opportunistic feeders consuming
particles from 5-50 microns.  I would like to identify a protist with
the following qualities:

Essentials
5-50 micron diameter
free-swimming
viable in fresh water
easily digestible
can be axenically cultured relatively inexpensively

Desirable
tends to accumulate in the top 1 cm of the water
axenic culture media is inexpensive
can be freeze-dried

Thanks,
Mark Benedict
