Abstract

The potential hazards from water resources available for fish farming in Suez Canal area, Egypt were studied. The study was based on different water sources of three farms. The first, located in Ataa El Mataria, has Bahr El-Baqar (sewage water), as the main water source; the second farm is located in Nemra 3; there, the agricultural drainage is the main water source; the third farm is located in Kilo 11 and receives its water supply from treated sewage water. The total viable bacterial count  (TVB) , total coli form (TC ), fecal coliform (FC ), fecal streptococci (FS ) and Aeromonas spp.( Aero) and heavy metals (Cd, Cu, Pb and Zn) contaminations were investigated in biotic (fish) and a biotic compartment (sediments and water) of the fish farming ponds and water supplies. The results indicated that the commercial fish farming especially the one in Ataa El Mataria has higher levels of biological and chemical contamination in their aquatic environment and their production of finfish than those in Lake Timsah (this lake represents the main source of seafood supplied by fisheries in Ismailia area). The level of contamination is also higher than the international levels for public health and safety concerns. It can be concluded that the use of aquaculture

products in Suez Canal area may pose a potential health hazard.
