Among those with food items (n = 149), insects were most common and occurred in 66% of fish, followed by formulated feed (60%), diatoms (40%), cladocerans (36%), rotifers (35%), filamentous algae (32%), bryozoan statoblasts (19%), and copepods (12%; Table 1).
During the summer many species of cyanobacteria, diatoms such as Asterionella and Fragellaria, dinoflagellates, desmids, calanoid copepods, and cladocerans are present whereas in the winter there are centric diatoms, calanoid copepods, the cyanobacterium Anabacna, and small flagellated algae.
Although cladocerans made up such a small percentage of the zooplankton counted that they could not be accurately analyzed, this taxa is worth mentioning in context to this study as a majority of zooplankton-cyanobacteria studies use cladocerans.
Mass development of cladocerans starts in June when they make up about 30% of the total zooplankton biomass; they dominate in biomass in July (mainly the genus Daphnia) and account for about 50% of biomass in the autumn months (genus Bosmina).
Others, particularly cladocerans, have developed cyclomorphological features to prevent ingestion by vertebrate, or gape-limited predators (Wetzel 2001).
