Notes on some Cladocera from Iran

Abstract

The material with which the following notes are concerned was taken by Dr. Goiti NAKATA, FAO Expert, Razi Institute in Teheran, Iran. It was collected with a small tow-net hauling in a marsh at Balan-Abad near Teheran on August 15, 1965. The temperature of water of that marsh was 20°C at an atmospheric temperature 22°C. The sample was abundant in minute diatoms and remains of an ostracod. There were found five species of Cladocera, all of which belong to the family Chydoridae living among aquatic vegetation. No typical planktonic forms occurred. The writer is grateful to Dr. NAKATA for providing this meterial.
