Abstract
The investigation of fish farm discharge effect on drainage network in Kafer El-Sheikh Governorate, three fish farms near by the three drains (near by El-Hax, El-Far and El-Canal drains) with three different production capacities were studied by examining water physicochemical criteria and natural wetland system. Water and plant samples were collected once during summer and winter using a quantitative technique. Results showed a significant increase in oxidizabile organic materials, Total Suspended Solids (TSS) concentrations, a decline in dissolved oxygen (D.O) concentration and pH in the outflow compared to Egyptian Environment Law 9/2009. Rhizofiltration application as one of phytoremediation technology included the emergent plants (Boos - Phragmites australis), Eichhornia crassipes and Canna indica were utilized to extract, sequester, and/or detoxify pollutants as in-stream wetland system at downstream fish farms sites that improved drainage water quality. In conclusion, the results have important consequences for future monitoring strategies of watershed and management of their gradual ecological improvement.
