SS-ROTIFERS
Question:
Can anyone recommend a reliable source for some true
ss-rotifers for
marine finfish larvae? I am looking for some starter cultures with rotifers
sized below 180-200 microns.

I can highly recommend using Micromonas pusilla as a
food source for Brachionus rotundiformis.
From my research, Micromonas pusilla increased the initial population by
1400% compared to 250% for Nannochloropsis salina.

We are currently using one SS rotifer strain at the
CCMAR ; the mean size is 180µm, but juveniles are even smaller (~100µm).
We get this strain (Brachionus rotdundiformis var. Tschugunoff ; cf.
the paper from Hagiwara, 1995) from the Artemia Research Center
(Ghent-BELGIUM). It is one of the best place to get all kind of rotifer
strain, at last in Europe. Regarding to the culture, we grow them at 28-30°C
and low salinity (around 12ppm). With these parameters, we have got the best
results.
