  Author(s): Ahmed M.M. Heneash and Ahmed E. Alprol*
  
  The objective of this study assess the effects of physico-chemical parameters and dietary active commercial wood charcoal (CWC) levels on the zooplankton standing crop in addition to growth and biochemical of red tilapias in fifteen fish cement ponds for period an eight weeks feeding trial during 2019. The results declared that, water temperature, pH and salinity didn´t show any major differences among wood charcoal treatments when measured inside fish ponds, while dissolved oxygen, ammonia, moisture, ash and total lipid are significantly (P<0.05) enhancement affected by the increment in (CWC) levels. Mean range of physico-chemical factors were: temperature 28.1°C (Week 7) to 30.9°C (Week 0), salinty 8.4 ppt (Week 3) to 5 ppt (Week 6 & 7), pH 8.4 (Week 4) and 9 (Week 3), Dissolved oxygen 4.44 mg/l (Week 4) to 7.80 mg/l (Week 0) and ammonia 0.01-00.04 μg/l (Week..
