effects of water Quality on Aquaponic system AThesis submitted in partial Fulfillment of the Requirement of

Abstract

The main target of this study was to design the aquaponic system and to evaluate its capability to produce more than one crop (plant and fish) in integrated system production with soil less and without use of verminous or chemical pesticide also to determine ability of plants to uptake the ammonia after converted it to nitrate and effects of aquaponic on water quality. The experiment was conducted for 60 days; from June/ 9/ 2016 to August/ 8/ 2016 and an aquaponic system was developed at the fish hatchery, Department of fisheries science and wildlife, college of animal production Science and technology, Sudan University of science and technology. Forty aquaponic fish were distributed in 2 fiber glass tanks at a density of 20 fish/tank; fish were fed on 3% of body weight twice a day. Ten days after experimental stared there’s no mortality on fish and no replacement but mortality started 13 days later and no replacement was done. The percentage of mortality at the end of the experimental was 17.5%. Statistical analysis was performed using the Analysis of variance one way (ANOVA) and Duncan’s multiple Range Test, to determine differences between parameters means at significance rate of P < 0.05. All statistics was carrying out using Statistical Analysis program (SPSS, 16). The result of water quality obtained from this study shown significant difference in all parameters measured during this study were (p≤0.05) between T.A, T.B and plat tray treatment. Key words: aquaponic, Nile tlapia,Water qualty , Nitrate ,Ammonia.
