Effect of progesterone on sexual reproduction of Brachionus manjavacas ...
WebRotifers ( Brachionus spp.) are extensively used as first feed in marine larviculture. They are quite small (50 μm–2 mm), slow swimming, and are relatively easy to culture ( Lavens and Sorgeloos, 1996 ). Rotifers can be used for both freshwater and saltwater larvae, as different rotifer species can tolerate a wide range of salinities (0–50 ppt). Brachionus species can normally reproduce sexually and asexually (cyclical parthenogenesis). Sexual reproduction (termed Mixis) is usually induced when population density increases. Mixis in Brachionus plicatilis has been shown to be induced by a density-dependent chemical cue.
