Although Keratella sp. This food style has its influence with the Islamic community. Feeding studies with different algal types or with natural phytoplankton mixtures have established the importance of flagellated algal cells, such as cryptomonads and chrysomonads, in its diet ( Gilbert and Bogdan, 1981 ), although it may eat detritus, bacteria and picoplanktonic algae as an additional food resource ( Pourriot, 1965 ; Ronneberger, 1998 ).
