This paper presents biochemical content such as fatty acids, sterols, total protein, lipophilic vitamins, and antioxidant parameters of mixed cladoceran samples (Daphnia sp., Diaphanosoma brachyurum) in the freshwater ecosystem. Results indicated that predominant fatty acids were 20:5n3 (19.85%), 16:1n7 (17.29%), 16:0 (13.1%), 24:0 (12.55%), 18:0 (10.68%) and 18:1n9 (7.99%). Cholesterol was the principal sterol (194.1 µg/g) in cladocerans. Total protein was calculated as 52.26 µg/g in cladocerans. α-tocopherol (vitamin E) was the most important vitamin (4.6 µg/g) among lipophilic vitamins. Glutathione (GSH) was quite high (450µg/g) than MDA (11.5 nmol/g).
