Abstract
From October 1977 to October 1978, 429 planktonic samples were collected from Lake Gamelin. The analysis of these samples showed that Lake Gamelin contained 17 zooplanktonic species: 6 Rotifers, 5 Copepods, and 6 Cladoceran species. Cyclops scutifer and Keratella longispina composed the most important group and the subdominating species were Polyarthra vulgaris, Trichocerca cylindrica and Diaptomus minutus, the other species were scarce and Cladocera were never abundant. The zooplanctonic average density was 33.1 ind./l during the year with extremes of 20.8 to 53.0 ind./l obtained during the months of March and October. In terms of numeric abundance, Copepods represented 53 %, Rotifers 41 %, and Cladocera 6 % of the total zooplankton.
