The nauplii production was 272.0±22.7 (±SE), 727.3±60.6, 267.6±22.3, 147.0±12.3, 25.0±2.1 and 33.6±2.8 ind./L and copepodit production was 124.3±10.4, 311.3±25.9, 183.0±15.3, 59.0±4.9, 14.3±1.2, and 17.6±1.4 ind./L fed algae, algae+soil, vegetable, vegetable+soil, manure, and manure+soil, respectively. Correspondingly, the adult production was 51.6±40.3, 208.5±17.5, 192.7±16.1, 91.7±7.6, 8.7±0.7 and 8.7±0.7 ind./L, respectively. The maximum body length (663.8±29.1 µm) and width (526.2±23.7 µm) of A. robustus were recorded when fed with vegetable+soil and vegetable, respectively. Results showed that D. magna fed on manure and vegetable had Acinetobacter bacteria and with Scenedesmus by Aeromonas bacteria while A. robustus fed on manure, vegetable and Scenedesmus dominated by Neisseria , Enterobacteria and Alcaligenes , respectively. The highest bacteria density was obtained in D. magna culture medium fed on Scenedesmus (5×10 4 cell/ml) and the lowest fed on manure (9×10 3 cell/ml). In addition, at A. robustus cultures the highest and lowest bacteria density were obtained 1.4×10 4 and 5.0×10 3 cell/ml, respectively. The maximum BOD was recorded in A. robustus fed on vegetable (90 mg/l) and the minimum in D. magna fed on manure (28 mg/l). The maximum COD (313 mg/l) and minimum (43 mg/l) were recorded in A. robustus fed on vegetable and Scenedesmus , respectively. The study illustrated that animal and plant organic matters can be used as suitable replacement for microalgae for growth and production of Zooplankton.
