Twelve thousand fries of Nile Tilapia (Oreochromas niloticus) were stocked in 6 ponds, three ponds were supplemented with chicken-manure and others with artificial diet. The Aeromonas. and Pseudomonas spps. were isolated from all ponds while the Salmonella and Enterococcus spps. were isolated from the manure supplemented ponds. As a General observation, the antimicrobial resistance of the isolated bacteria was high with oxytetracyclin, low with ciprofloxacin. The Pseudomonas spp. seemed to be the highest resistant to the used antimicrobials, while the Enterococcus spp. was the lowest. The total psychrotrophic counts /g of fish-flesh, collected from the fish of manure supplemented pond, showed significantly higher mean value than that of fish supplemented with artificial diet. The psychrotrophic strains were isolated from all ponds with varied frequency and percentage at both 0 time and after 168 h of ice storage, however, Coliform, Enterococcus spp., Flavobacterium spp., Staphylococcal spp. and Moraxella spp. were only isolated from fish-flesh samples from manure supplemented ponds. It could be concluded that, using of the chicken manure supplement for aquaculture may transfer some food-borne or zoonotic bacteria to the aquaculture and consequently to the consumer. Moreover, may create multidrug- resistant bacterial strains and decrease the fish quality and shelf-life.
