Descrição/Abstract
The diet of Engraulicypris sardella (Cyprinidae) larvae was determined from the open waters of Lake Malawi, Africa. The guts of first-feeding larvae of 2-3 mm total length (TL) usually contained many cells of 5-9 um diameter tentatively identified as a non-colonial green alga (Chlorophyta). The number of these cells in the guts of larvae declined as larvae increased in size, and were not found in larvae greater than 9 mm TL. Other types of phytoplankton were rarely seen in the guts of larvae. Copepod nauplii were eaten by larvae greater than 4 mm TL, and copepodite copepods and cladoceans by larvae greater than 5 mm TL. The biomass of open water crustacean zooplankton and E.sardella larvae were determined over a 2-year sampling programme.
