Daphnia do not have contractile vacuoles. Contractile vacuoles are pretty much limited to some protists and sponges. Daphnia, being crustaceans in the Phylum Arthropoda (Kingdom Animalia), have a complex, kidney-like organ built upon basic units called metanephridia. I did a simple search on "daphnia osmoregulation" and came up with the following URL which has some good, basic information on osmoregulation in animals in general.

Hope this has been useful.
