PRACTICAL USE OF ROTIFER CYSTS

The availability of marine rotifer Brachionus plicatilis cysts for aqu aculture has long been suggested. Only a few studies, however, reporte d trials of mass formation of rotifer cysts as well as their applicati on to aquaculture. The current paper summarizes our works relating to those topics, which are based on accumulated fundamental information o n B. plicatilis cyst formation. These include the selection of prefera ble rotifer clones, use of preserved diets for cyst formation, bacteri al effect on rotifer sexual reproduction, actual trials of cyst format ion and application of rotifer cysts for larval rearing practices.
