Identification of cultured Brachionus rotifers based on RFLP and SSCP screening.

The marine finfish industry worldwide depends greatly on the mass culture of Brachionus rotifers. Recently, molecular data have revealed a more complicated view about the species status of Brachionus rotifers than previous mainly morphological assessments. Under this view, Brachionus rotifers are comprised of many morphologically similar, albeit genetically differentiated, cryptic members of larger groups.
