WebDec 16, 2008 · Both B. plicatilis and B. rotundiformis are used as live food for aquaculture, but the two species have different properties for population growth and other traits. The highest population growth was observed at 30°C and 35°C for B. plicatilis (so-called L type) and B. rotundiformis (SS type), respectively [ 17 ]. WebA detailed study of the life history of the rotifer Brachionus plicatilis was done at 20 °C, 20 ppt salinity, and 90 mg C 1 −1 food concentration. Rotifers were grown individually in culture plate wells (150 µl culture volume) and fed Isochrysis galbana Tahiti, Tetraselmis sp., Nannochloris atomus, or a l : 1 mixture (weight) of two of the algae.

Ecological genetics of Brachionus sympatric sibling species
WebJan 27, 2014 · Several localities were screened for the presence of the B. plicatilis species complex in Iran; the species complex was found in six water bodies located in the West Azarbaijan and Hormozgan provinces, described in Malekzadeh-Viayeh (2010) ( Table 1, Supporting Information Appendix S1 ). WebB. plicatilis has a mating recognition system different from those of either B. rotundiformis SM or SS, whereas the two B. rotundiformis groups had partially differentiated mating preferences. Cross-mating experiments performed in the laboratory failed to produce any detectable hybrids. Brachionus plicatilis is a euryhaline (tolerate a wide range of salinity) rotifer in the family Brachionidae, and is possibly the only commercially important rotifer, being raised in the aquaculture industry as food for fish larvae. It has a broad distribution in salt lakes around the world and has become a model system for … See more Brachionus species can normally reproduce asexually and sexually (cyclical parthenogenesis). Sexual reproduction (termed Mixis) is usually induced when population density increases.
