Abstract
We studied the zooplankton community structure in a set of 2 small shallow ponds in integrated fish and duck
production system in Bié province, Angola. The objective was to evaluate quality of natural food resources
for farmed fish. We present the results in the percentage of the occurrence of respective groups or species.
Dominant component of the zooplankton was small cladoceran Moina macrocopa that represents 95% resp. 93% of all
sampled specimens. Other identified species of cladocerans were Ceriodaphnia setosa and Chydorus sphaericus.
Rotifers were represented by species Brachionus falcatus and Asplanchna priodonta. Copepods were not classified.
