| Abstract: | In 1996,The community structure of Liaocheng Round-city Lake was preliminarily studied. It was found there are 63 species of zooplankton in the lake,of which 40 belong to Protozoa, 15 to Rotifera, 3 to Cladocera, 5 to Copepoda. The Dominants are Askenasia volvox, Halteria grandinella, Strobilidium grans. Brachionus calyciflorus, Brachionus diversicornis. Tintinnidium fiuviatile, Strobidinopsis grans, Cylidium citryllys,and Asplanchna sp. are found constantly. The average density of zooplankton is 10754 individuals per litre of water,of which protozoa is 87.4% and rotifera 12.5%. |
