Notes

The rotifer Brachionus calyciflorus can utilize the cyanobacterium Anabaena flos-aquae as either a sole or complementary food source in laboratory culture. Positive population growth rates accompany food densities 0 or 100 ug dry weight/ml, but slightly negative rates are found at a lower density (1.0 ug/ml). These are consistent survivorship and reproduction with the latter food. A 1:1 mixture (by dry weight) of Euglena gracilis and A. flos-aquae (NRC-44-1) produces survivorship comparable to that of control rotifer fed E. gracilis alone, but elicits significantly greater fecundity and population growth rates than and with the control food suspension at the same biomass density.
