Rotifers are smaller than newly hatched brineshrimp and vital as a first feed for many small fish species.
As a basic guide for culturing marine rotifers: aim for a salinity of 20-22+ppt (approx 1.015 SG), light of 500-2000 lux, temperature of around 25 deg. C
DAY 0: setup a new culture with 1 part mature culture and 3 parts new water. Aerate very gently to avoid stripping the eggs off the females. Add 10ml phyto or 1 drop of Roti-rich per litre of culture per day.
DAY 1-6: continue to feed at 10 ml phyto or 1 drop of Roti-rich per litre of culture per day.
DAY 7: harvest 3/4 of the mature culture for feeding and use a 53 micron strainer to concentrate the rotifers prior to feeding. Use the remaining mature culture to set up a new culture.
If you can establish 7-8 rotifer cultures you should have sufficient numbers to harvest on a daily basis.
An alternate culture technique requiring less effort is: 2 part rotifer culture and 3 parts phytoplankton and simply harvest once the phytoplankton has been consumed and water becomes clear.
