| Abstract | ||
| Indoor fish ponds are an economic activity that helps to apply the needs of fish meat which also have the advantage of being conducted on many scales. The main objective of this study is to make evaluation of using micro-sprinkler as an alternate for traditional nozzle sprayer aerators to obtain advantages of ease of implementation and save energy for indoor fish ponds. The study has been carried out on homosexual Tilapia fish (Oreochromis niloticus) in a glass tank which was open from the top side and put in a closed room. The evaluation of water environment parameters showed that Ammonia concentration (NH3), Potential hydrogen (pH), Electric conductivity (EC), and Turbidity (Tur) were in acceptable limits to keep fish life. There was reverse proportional relationship between dissolved oxygen content (DO) and all of NH3, EC, and Tur. The proposed aeration system succeeds to apply oxygen demands when required with low energy consumption and standard aeration efficiency (SAE) value of 5.0 kg O2/kW. h which was near to the (SAE) of nozzle sprayer. Feed conversion ratio (FCR) by the end of growing season was 1.88 with an average of fish weight 180g. The study revealed the possibility of using micro-sprinklers for indoor fish ponds aeration and recommended to investigate other possible management strategies to improve the SAE of the system and obtain higher fish productivity | ||
