碩士 / 高苑科技大學 / 化工與生化工程研究所 / 104 / In this study, the aquaponic system was set up outdoors and adopted sunlight as the light source to save energy. The processed fish feed and mixed natural fish feed (Sesame dregs, soybean dregs, rice bran: 1:1:1) were supplied for the fish (Zhu Wenjin). The ceramic ring and oyster shell provided the bio media for the transfer of ammonia-nitrogen to nitrate-nitrogen which could be assimilated by vegetables. Moreover, the water quality of the aquaponic system,the growth of vegetables (Oilseed Rape,Chinese Cabbage, Garland Chrysanthemum) , and the nitrate of vegetables were investigated.
The results showed that bio media and food of fish affected the water quality and the nitrate amount for vegetables. The most fast and steady growth was Edible Rape on the combination of oyster shell medium and mixed natural fish feed. However, the water containsed a lot of turbidity. It was due to the oyster shell and mixed natural fish feed and the post-filter was not efficient. Further, the Edible Rape still could grow fast by the combination of ceramic ring and processed fish feed. However, the Chinese Mustard and Crown Daisy grew slowly and the effluent water was very clear after the combination process of ceramic ring and processed fish feed.
On the other hand, the water quality of dissolved oxygen (DO) was 7.48-8.68 mg/L. It indicated that the DO provided the growth of fish effectively. Moreover, the combination of ceramic ring with processed fish feed resulted in low pH of water and no correlation with the growth of fish. On the other hand, the amounts of nitrate of all the harvested vegetables were lower than the EU nitrate regulation No. 563/2002 summer criteria of 2500ppm. The combination of oyster shell and mixed natural fish feed contained lower nitrate for vegetables.
