The physical growth of Oreochromis niloticus and three plant species on the aquaponic technology

The physical growth of Oreochromis niloticus fish and three types of plants consist of Ipomoea Aquatica, Brassica rapa, and Capsicum annuum on the aquaponic technology have been studied. The aquaponic technology system has been done with 200 fishes m^-3, water pump with 15 watts solar energy panel, physical and biological filter, and deep flow technique (DFT). In this study, we have reported that the specific growth rate (SGR), survival (SR), Feed conversion ratio (FCR), and Wet weight (W) are used as the physical growth indicator of Oreochromis niloticus fish, while the length and the number of leaves of plants are used as the physical growth indicator of plants. The physical growth of Oreochromis niloticus fish showed that SGR is 5,56% day^-1, SR is 97,67%, FCR is 0,92g and the wet weight is 1220g. The physical growth of the plant in aquaponic technology systems has been compared with the hydroponic treatment systems as controls. Analysis with t-test shows that physical growth of Ipomoea Aquatica and Brassica rapa has no significant difference respectively, whereas Capsicum annuum has significant differences compared with controls. Also, Brassica rapa in the aquaponic technology system shows a more yellow leaf color than the control. Based on these results, we conclude that aquaponic technology system provides effective results for the physical growth of Oreochromis niloticus with Ipomoea Aquatica, while additional nutrients for the both Brassica rapa and Capsicum annuum are required.
