✦ Synopsis

Twenty species of planktonic rotifers were important in Lake Biel during 1978 . Eight species were present throughout the year, four species occurred only in spring and eight species in summer or autumn . Rotifer numbers attained two major maxima, one in May (19 .3 106 ind . m2) and one in August (16 .5 10 6 ind . M-2) . Predominant genera were Synchaeta, Polyarthra, Conochilus, Asplanchna and Keratella . Within the genus Synchaeta a succession of different species was observed .

Zooplankton samples from the middle reach of the Po River were collected daily from 27 July to 24 August 1988 from a station located near Viadana. Changes in the biocoenosis structure were analyzed in relation to variations in flow rate. Rotifers accounted for more than 99% of the total zooplankton
