The paper describes the role of simplest crustaceans in the food of f shes in the Khojahasan lake of the Absheron peninsula. In the course of the research 57 fish samples belonging to two species [Europian carp (Cyprinus carpio) and golden carp (Carassius auratus gibelio)] from the Khojahasan lake were studied. Eight types of food components [chironomus larvaes (Procladius sp., Stempellina sp., Tanytarsus sp.), oligochaetes (Nais sp., Limnodrilus sp., Tubifex sp.), rotators (Brachionus sp., Keratella sp.), simplest crustaceans (Daphnia sp., Acanthocyclops sp.), other insect larvaes, detrit, plant residues, algae] are found in the gastrointestinal tract of mature individuals of Europian carp, six types of food components [chironomus larvaes (Psectrocladius sp., Tanypus sp.), oligochaetes (Limnodrilus sp., Tubifex sp.), rotators, simplest crustacean, plant residues, algae] are found in the gastrointestinal tract of golden carp in spring and summer. The result of the analysis of the gastrointestinal tract of juveniles of Europian carp show that zooplankton is the main and starting food from beginning of April until end of June.
