Brachionus

about 30 [1] Schizocerca Daday, 1883 Brachionus is a genus of planktonic rotifers occurring in freshwater, alkaline and brackish water.

However, the composition of rotifers generally does not satisfy the nutritional requirements of fish larvae,[3] and large amounts of research have been invested in improving the lipid, vitamin and mineral composition of rotifers to better meet the requirements of fish larvae[4][5][6] Brachionus species can normally reproduce sexually and asexually (cyclical parthenogenesis).

In this species, obligate parthenogenesis can be inherited by a recessive allele, which leads to loss of sexual reproduction in homozygous offspring.

[8][9] In Brachionus manjavacas rotifers, offspring's survival and its cell's ability to growth and division decrease with advancing age of mother.
