Abstract

This study was performed in order to determine the Cladocera and Copepoda living on Typha spp., Ceratophyllum spp. and Nymphaea spp. constituting the dominant species in Gala Lake National Park and to reveal their macrophyt preferences. 8 Cladocera and 5 Copepoda species were determined on these plants. The cladoceran Chydorus sphaericus was found on all macrophytes while C. latus preferred Ceratophyllum spp., Pleuroxus aduncus preferred Nymphaea spp. and Alona guttata, A.costata, A. rectangula, A.guadrangularis and Oxyurella tenuicaudis preferred Typha spp. The Copepoda species Nitocra hibernica was found on all macrophytes while N. lacustris preferred Typha spp. and Ceratophyllum spp., Onychocamptus mohammed prefered Nymphaea spp. and Horsiella breviconis and H.trisetosa prefered Typha spp.
