From April 1992 lo May 1993, zooplankton samples were collected monthly by means of horizontal tows in nine sites of the lake. Prior to the towing, temperature of surface water, transparency (Secchi), pH and dissolved oxygen were evaluated. A total of 31 zooplankton forrns, inc\uding 14 species of rotifers, tbree copepods, five cladocerans and one ostracod, as well as protozoans (mainly vorticellids and ciliates), were detected. Rotifers were the dominant organisms, mainly Brachionus havanaensis (27.6 ind i-I), B. angularis (6.9 ind i-I), Keratella cochlearis (4.9 ind i-I), Conochilus unicornis (10.8 ind 1-1) and C. dossuarius ( 3.1 ind i-I).
